The Hudson River Watershed, including the Hudson and Mohawk rivers
The Hudson River is a 315-mile (507 km) river that flows from north to south primarily through eastern New York in the United States. The river originates in the Adirondack Mountains of Upstate New York, flows southward through the Hudson Valley to the Upper New York Bay between New York City and Jersey City. It eventually drains into the Atlantic Ocean at New York Harbor. The river serves as a political boundary between the states of New Jersey and New York at its southern end. Further north, it marks local boundaries between several New York counties. The lower half of the river is a tidal estuary, deeper than the body of water into which it flows, occupying the Hudson Fjord, an inlet which formed during the most recent period of North American glaciation, estimated at 26,000 to 13,300 years ago. Tidal waters influence the Hudson's flow from as far north as the city of Troy.
The river is named after Henry Hudson, an Englishman sailing for the Dutch East India Company, who explored it in 1609, and after whom Hudson Bay in Canada is also named. It had previously been observed by Italian explorer Giovanni da Verrazzano sailing for King Francis I of France in 1524, as he became the first European known to have entered the Upper New York Bay, but he considered the river to be an estuary. The Dutch called the river the North River – with the Delaware River called the South River – and it formed the spine of the Dutch colony of New Netherland. Settlements of the colony clustered around the Hudson, and its strategic importance as the gateway to the American interior led to years of competition between the English and the Dutch over control of the river and colony.
During the eighteenth century, the river valley and its inhabitants were the subject and inspiration of Washington Irving, the first internationally acclaimed American author. In the nineteenth century, the area inspired the Hudson River School of landscape painting, an American pastoral style, as well as the concepts of environmentalism and wilderness. The Hudson was also the eastern outlet for the Erie Canal, which, when completed in 1825, became an important transportation artery for the early-19th-century United States.
The source of the Hudson River is Lake Tear of the Clouds in the Adirondack Park at an altitude of 4,322 feet (1,317 m). However, the river is not cartographically called the Hudson River until miles downstream. The river is named Feldspar Brook until its confluence with the Opalescent River, and then is named the Opalescent River until the river reaches Calamity Brook, flowing south from the outlet of Henderson Lake. From that point on, the stream is cartographically known as the Hudson River. The U.S. Geological Survey (USGS) uses this cartographical definition.
The longest source of the Hudson River as shown on the most detailed USGS maps is the "Opalescent River" on the west slopes of Little Marcy Mountain,originating two miles north of Lake Tear of the Clouds, several miles, past the Flowed Lands, to the Hudson River. and a mile longer than "Feldspar Brook", which flows out of that lake in the Adirondack Mountains. Popular culture and convention, however, more often cite the photogenic Lake Tear of the Clouds as the source.
Using river names as seen on maps, Indian Pass Brook flows into Henderson Lake, and the outlet from Henderson Lake flows east and meets the southwest flowing Calamity Brook. The confluence of the two rivers is where maps begin to use the Hudson River name. South of the outlet of Sanford Lake, the Opalescent River flows into the Hudson.
The Hudson then flows south, taking in Beaver Brook and the outlet of Lake Harris. After its confluence with the Indian River, the Hudson forms the boundary between Essex and Hamilton counties. In the hamlet of North River, the Hudson flows entirely in Warren County and takes in the Schroon River. Further south, the river forms the boundary between Warren and Saratoga Counties. The river then takes in the Sacandaga River from the Great Sacandaga Lake. Shortly thereafter, the river leaves the Adirondack Park, flows under Interstate 87, and through Glens Falls, just south of Lake George although receiving no streamflow from the lake. It next goes through Hudson Falls. At this point the river forms the boundary between Washington and Saratoga Counties. 200 feet (61 m). Just south in Fort Edward, the river reaches its confluence with the Champlain Canal, which historically provided boat traffic between New York City and Montreal and the rest of Eastern Canada via the Hudson, Lake Champlain and the Saint Lawrence Seaway. Further south the Hudson takes in water from the Batten Kill River and Fish Creek near Schuylerville. The river then forms the boundary between Saratoga and Rensselaer counties. The river then enters the heart of the Capital District. It takes in water from the Hoosic River, which extends into Massachusetts. Shortly thereafter the river has its confluence with the Mohawk River, the largest tributary of the Hudson River, in Waterford. The river then reaches the Federal Dam in Troy, marking an impoundment of the river. At an elevation of 2 feet (0.61 m), the bottom of the dam marks the beginning of the tidal influence in the Hudson as well as the beginning of the lower Hudson River.Here the river has an elevation of
South of the Federal Dam, the Hudson River begins to widen considerably. The river enters the Hudson Valley, flowing along the west bank of Albany and the east bank of Rensselaer. Interstate 90 crosses the Hudson into Albany at this point in the river. The Hudson then leaves the Capital District, forming the boundary between Greene and Columbia Counties. It then meets its confluence with Schodack Creek, widening considerably at this point. After flowing by Hudson, the river forms the boundary between Ulster and Columbia Counties and Ulster and Dutchess Counties, passing Germantown and Kingston. The Delaware and Hudson Canal meets the river at this point. The river then flows by Hyde Park, former residence of Franklin D. Roosevelt, and alongside the city of Poughkeepsie, flowing under the Walkway over the Hudson and the Mid-Hudson Bridge. Afterwards, the Hudson passes Wappingers Falls and takes in Wappinger Creek. The river then forms the boundary between Orange and Dutchess Counties. It flows between Newburgh and Beacon and under the Newburgh Beacon Bridge, taking in the Fishkill Creek. In this area, between Gee's Point at the US Military Academy and Constitution Island, an area known as "World's End" marks the deepest part of the Hudson, at 202 feet (62 m). Shortly thereafter, the river enters the Hudson Highlands between Putnam and Orange Counties, flowing between mountains such as Storm King Mountain, Breakneck Ridge, and Bear Mountain. The river narrows considerably here before flowing under the Bear Mountain Bridge, which connects Westchester and Rockland Counties.
Afterward, leaving the Hudson Highlands, the river enters Haverstraw Bay, the widest point of the river at 3.5 miles (5.6 km) wide. Shortly thereafter, the river forms the Tappan Zee and flows under the Tappan Zee Bridge, which carries the New York State Thruway between Tarrytown and Nyack in Westchester and Rockland Counties respectively. At the state line with New Jersey the west bank of the Hudson enters Bergen County. The Palisades are large, rocky cliffs along the west bank of the river; also known as Bergen Hill at their lower end in Hudson County. Further south the east bank of the river becomes Yonkers and then the Riverdale neighborhood of the Bronx in New York City. South of the confluence of the Hudson and Spuyten Duyvil Creek, the east bank of the river becomes Manhattan. The river is sometimes still called the North River at this point. The George Washington Bridge crosses the river between Fort Lee and the Washington Heights neighborhood of Manhattan. The Lincoln Tunnel and the Holland Tunnel also cross under the river between Manhattan and New Jersey. South of the Battery, the river proper ends, meeting the East River to form Upper New York Bay, also known as New York Harbor. Its outflow continues through the Narrows between Brooklyn and Staten Island, under the Verrazzano Bridge, and into Lower New York Bay and the Atlantic Ocean.
The lower Hudson is actually a tidal estuary, with tidal influence extending as far as the Federal Dam in Troy. There are about two high tides and two low tides per day. As the tide rises, the tidal current moves northward, taking enough time that part of the river can be at high tide while another part can be at the bottom of its low tide.
Strong tides make parts of New York Harbor difficult and dangerous to navigate. During the winter, ice floes may drift south or north, depending upon the tides. The Mahican name of the river represents its partially estuarine nature: muh-he-kun-ne-tuk means "the river that flows both ways." 17,400 cubic feet (490 m3) per second on average. The mean fresh water discharge at the river's mouth in New York is approximately 21,900 cubic feet (620 m3) per second.Due to tidal influence from the ocean extending to Troy, NY, freshwater discharge is only about
The Hudson River is 315 miles (507 km) long, with depths of 30 feet (9.1 m) for the stretch south of the Federal Dam, dredged to maintain the river as a shipping route. Some sections there are around 160 feet deep, and the deepest part of the Hudson, known as "World's End" (between the US Military Academy and Constitution Island) has a depth of 202 feet (62 m).
The Hudson and its tributaries, notably the Mohawk River, drain an area of 13,000 square miles (34,000 km2), the Hudson River Watershed. It covers much of New York, as well as parts of Connecticut, Massachusetts, New Jersey, and Vermont.
Parts of the Hudson River form coves, such as Weehawken Cove in the towns of Hoboken and Weehawken in New Jersey.
New York Harbor, between the Narrows and the George Washington Bridge, has a mix of fresh and ocean water, mixed by wind and tides to create an increasing gradient of salinity from the river's top to its bottom. This varies with season, weather, variation of water circulation, and other factors; snowmelt at winter's end increases the freshwater flow downstream.
The salt line of the river varies from the north in Poughkeepsie to the south at Battery Park in New York City, though it usually lies near Newburgh. 11:
The Hudson is sometimes called, in geological terms, a drowned river. The rising sea levels after the retreat of the Wisconsin glaciation, the most recent ice age, have resulted in a marine incursion that drowned the coastal plain and brought salt water well above the mouth of the river. The deeply eroded old riverbed beyond the current shoreline, Hudson Canyon, is a rich fishing area. The former riverbed is clearly delineated beneath the waters of the Atlantic Ocean, extending to the edge of the continental shelf.As a result of the glaciation and the rising sea levels, the lower half of the river is now a tidal estuary that occupies the Hudson Fjord. The fjord is estimated to have formed between 26,000 and 13,300 years ago.
Along the river, the Palisades are of metamorphic basalt, or diabases, the Highlands are primarily granite and gneiss with intrusions, and from Beacon to Albany, shales and limestones, or mainly sedimentary rock. 13:
The Narrows were most likely formed about 6,000 years ago at the end of the last ice age. Previously, Staten Island and Long Island were connected, preventing the Hudson River from terminating via the Narrows. At that time, the Hudson River emptied into the Atlantic Ocean through a more westerly course through parts of present-day northern New Jersey, along the eastern side of the Watchung Mountains to Bound Brook, New Jersey and then on into the Atlantic Ocean via Raritan Bay. A buildup of water in the Upper New York Bay eventually allowed the Hudson River to break through previous land mass that was connecting Staten Island and Brooklyn to form the Narrows as it exists today. This allowed the Hudson River to find a shorter route to the Atlantic Ocean via its present course between New Jersey and New York City.
Suspended sediments, mainly consisting of clays eroded from glacial deposits and organic particles, can be found in abundance in the river. The Hudson has a relatively short history of erosion, so it does not have a large depositional plain near its mouth. This lack of significant deposits near the river mouth differs from most other American estuaries. Around New York Harbor, sediment also flows into the estuary from the ocean when the current is flowing north.
The river was called Ca-ho-ha-ta-te-a ("the river")by the Iroquois, and it was known as Muh-he-kun-ne-tuk ("river that flows two ways" or "waters that are never still" ) by the Mohican tribe who formerly inhabited both banks of the lower portion of the river. The meaning of the Mohican name comes from the river's long tidal range. The Delaware Tribe of Indians (Bartlesville, Oklahoma) considers the closely related Mohicans to be a part of the Lenape people, and so the Lenape also claim the Hudson as part of their ancestral territory, also calling it Muhheakantuck.
The first known European name for the river was the Rio San Antonio as named by the Portuguese explorer in Spain's employ, Estêvão Gomes, who explored the Mid-Atlantic coast in 1525.Another early name for the Hudson used by the Dutch was Rio de Montaigne. Later, they generally termed it the Noortrivier, or "North River", the Delaware River being known as the Zuidrivier, or "South River". Other occasional names for the Hudson included: Manhattes rieviere "Manhattan River", Groote Rivier "Great River", and de grootte Mouritse reviere, or "the Great Mouritse River" (Mourits is a Dutch surname). The translated name North River was used in the New York metropolitan area up until the early 1900s, with limited use continuing into the present day. The term persists in radio communication among commercial shipping traffic, especially below the Tappan Zee. The term also continues to be used in names of facilities in the river's southern portion, such as the North River piers, North River Tunnels, and the North River Wastewater Treatment Plant. It is believed that the first use of the name Hudson River in a map was in a map created by the cartographer John Carwitham in 1740.
In 1939, the magazine Life described the river as "America's Rhine", comparing it to the 40-mile (64 km) stretch of the Rhine in Central and Western Europe.
Various stretches of the river have their own historical names, many created by early Dutch explorers and settlers. The stretches all have similar sailing conditions, and the names were commonly used until the early common use of the steamboat. These names include, from south to north: the Great Chip Reach, Tappan Reach, Haverstroo Reach, Seylmakers' Reach, Crescent or Cook's Reach, Hoge's or High Reach, Martyr's or Martelaire Reach, Fisher's Reach, Lange Rack or Long Reach, Vasterack or Vaste Reach, Kleverack or Claverack, Backerack or Baker's Reach, Jan Playsier's Reach, and Hart's or Hunter's Reach. 10:
The area around Hudson River was inhabited by indigenous peoples ages before Europeans arrived. The Lenape, Wappinger, and Mahican branches of the Algonquins lived along the river,mostly in peace with the other groups. The Algonquins in the region mainly lived in small clans and villages throughout the area. One major settlement was called Navish, which was located at Croton Point, overlooking the Hudson River. Other settlements were located in various locations throughout the Hudson Highlands. Many villagers lived in various types of houses, which the Algonquins called wigwams, though large families often lived in longhouses that could be a hundred feet long. At the associated villages, they grew corn, beans, and squash. They also gathered other types of plant foods, such as hickory nuts and many other wild fruits and tubers. In addition to agriculture, the Algonquins also fished in the Hudson River, focusing on various species of freshwater fish, as well as various variations of striped bass, American eels, sturgeon, herring, and shad. Oyster beds were also common on the river floor, which provided an extra source of nutrition. Land hunting consisted of turkey, deer, bear, and other animals.
The lower Hudson River was inhabited by the Lenape,while further north, the Wappingers lived from Manhattan Island up to Poughkeepsie. They traded with both the Lenape to the south and the Mahicans to the north. The Mahicans lived in the northern part of the valley from present-day Kingston to Lake Champlain, with their capital located near present-day Albany.
John Cabot is credited for the Old World's discovery of continental North America, with his journey in 1497 along the continent's coast. In 1524, Florentine explorer Giovanni da Verrazzano sailed north along the Atlantic seaboard and into New York Harbor,however he left the harbor shortly thereafter, without navigating into the Hudson River. In 1598, Dutch men employed by the Greenland Company wintered in New York Bay. Eleven years later, the Dutch East India Company financed English navigator Henry Hudson in his search for the Northwest Passage. During the search, Hudson decided to sail his ship up the river that would later be named after him. His travel up the ever-widening river led him to Haverstraw Bay, leading him to believe he had successfully reached the Northwest Passage. He landed on the western shore of the bay and claimed the territory for the Netherlands. He then proceeded upstream as far as present-day Troy before concluding that no such strait existed there.
The Dutch subsequently began to colonize the region, establishing the colony of New Netherland, including three major fur-trading outposts: New Amsterdam, Wiltwyck, and Fort Orange.New Amsterdam was founded at the mouth of the Hudson River, and would later become known as New York City. Wiltwyck was founded roughly halfway up the Hudson River, and would later become Kingston. Fort Orange was founded on the river north of Wiltwyck, and later became known as Albany. The Dutch West India Company operated a monopoly on the region for roughly twenty years before other businessmen were allowed to set up their own ventures in the colony. In 1647, Director-General Peter Stuyvesant took over management of the colony, and surrendered it in 1664 to the British, who had invaded the largely-defenseless New Amsterdam. New Amsterdam and the colony of New Netherland were renamed New York, after the Duke of York.
Under British colonial rule, the Hudson Valley became an agricultural hub. Manors were developed on the east side of the river, and the west side contained many smaller and independent farms.In 1754, the Albany Plan of Union was created at Albany City Hall on the Hudson. The plan allowed the colonies to treaty with the Iroquois and provided a framework for the Continental Congress.
During the American Revolutionary War, the British realized that the river's proximity to Lake George and Lake Champlain would allow their navy to control the water route from Montreal to New York City.British general John Burgoyne planned the Saratoga campaign, to control the river and therefore cut off the patriot hub of New England (to the river's east) from the South and Mid-Atlantic regions to the river's west. The action would allow the British to focus on rallying the support of loyalists in the southerly states. As a result, numerous battles were fought along the river and in nearby waterways. These include the Battle of Long Island, in August 1776 and the Battle of Harlem Heights the following month. Later that year, the British and Continental Armies were involved in skirmishes and battles in rivertowns of the Hudson in Westchester County, culminating in the Battle of White Plains.
Also in late 1776, New England militias fortified the river's choke point known as the Hudson Highlands, which included building Fort Clinton and Fort Montgomery on either side of the Hudson and a metal chain between the two. In 1777, Washington expected the British would attempt to control the Hudson River, however they instead conquered Philadelphia, and left a smaller force in New York City, with permission to strike the Hudson Valley at any time. The British attacked on October 5, 1777 in the Battle of Forts Clinton and Montgomery by sailing up the Hudson River, looting the village of Peeksill and capturing the two forts.In 1778, the Continentals constructed the Great West Point Chain in order to prevent another British fleet from sailing up the Hudson.
Hudson River School paintings reflect the themes of discovery, exploration, and settlement in America in the mid-19th century.The detailed and idealized paintings also typically depict a pastoral setting. The works often juxtapose peaceful agriculture and the remaining wilderness, which was fast disappearing from the Hudson Valley just as it was coming to be appreciated for its qualities of ruggedness and sublimity. The school characterizes the artistic body, its New York location, its landscape subject matter, and often its subject, the Hudson River. In general, Hudson River School artists believed that nature in the form of the American landscape was an ineffable manifestation of God, though the artists varied in the depth of their religious conviction. Their reverence for America's natural beauty was shared with contemporary American writers such as Henry David Thoreau and Ralph Waldo Emerson. The artist Thomas Cole is generally acknowledged as the founder of the Hudson River School, his work first being reviewed in 1825, while painters Frederic Edwin Church and Albert Bierstadt were the most successful painters of the school.
At the beginning of the 19th century, transportation from the US east coast into the mainland was difficult. Ships were the fastest vehicles at the time, as trains were still being developed and automobiles were roughly a century away. In order to facilitate shipping throughout the country's interior, numerous canals were constructed between internal bodies of water in the 1800s.One of the most significant canals of this era was the Erie Canal. The canal was built to link the Midwest to the Port of New York, a significant seaport during that time, by way of the Great Lakes, the canal, the Mohawk River, and the Hudson River. The completion of the canal enhanced the development of the American West, allowing settlers to travel west, send goods to markets in frontier cities, and export goods via the Hudson River and New York City. The completion of the canal made New York City one of the most vital ports in the nation, surpassing the Port of Philadelphia and ports in Massachusetts. After the completion of the Erie Canal, smaller canals were built to connect it with the new system. The Champlain Canal was built to connect the Hudson River near Troy to the southern end of Lake Champlain. This canal allowed boaters to travel from the St. Lawrence Seaway, and then British cities such as Montreal to the Hudson River and New York City. Another major canal was the Oswego Canal, which connected the Erie Canal to Oswego and Lake Ontario, and could be used to bypass Niagara Falls. The Cayuga-Seneca Canal connected the Erie Canal to Cayuga Lake and Seneca Lake. Farther south, the Delaware and Hudson Canal was built between the Delaware River at Honesdale, Pennsylvania, and the Hudson River at Kingston, New York. This canal enabled the transportation of coal, and later other goods as well, between the Delaware and Hudson River watersheds. The combination of these canals made the Hudson River one of the most vital waterways for trade in the nation.
During the Industrial Revolution, the Hudson River became a major location for production, especially around Albany and Troy. The river allowed for fast and easy transport of goods from the interior of the Northeast to the coast. Hundreds of factories were built around the Hudson, in towns including Poughkeepise, Newburgh, Kingston, and Hudson. The North Tarrytown Assembly (later owned by General Motors), on the river in Sleepy Hollow, was a large and notable example. The River links to the Erie Canal and Great Lakes, allowing manufacturing in the Midwest, including automobiles in Detroit, to use the river for transport. pp71–2) With industrialization came new technologies for transport, including steamboats for faster transport. In 1807, the North River Steamboat (later known as Clermont), became the first commercially successful steamboat. It carried passengers between New York City and Albany along the Hudson River.(
The Hudson River valley also proved to be a good area for railroads. The Hudson River Railroad was established in 1849 on the east side of the river as a way to bring passengers from New York City to Albany. The line was built as an alternative to the New York and Harlem Railroad for travel to Albany, and as a way to ease the concerns of cities along the river. The railroad was also used for commuting to New York City.Further north, the Livingston Avenue Bridge was opened in 1866 as a way to connect the Hudson River Railroad with the New York Central Railroad, which goes west to Buffalo. Smaller railroads existed north of this point. On the west side of the Hudson River, the West Shore Railroad opened to run passenger service from Weehawken, New Jersey to Albany, and then Buffalo. In 1889, the Poughkeepsie Railroad Bridge opened for rail service between Poughkeepsie and the west side of the river.
Starting in the 20th century, the technological requirements needed to build large crossings across the river were met. This was especially important by New York City, as the river is fairly wide at that point. In 1927, the Holland Tunnel opened between New Jersey and Lower Manhattan. The tunnel was the longest underwater tunnel in the world at the time, and used an advanced system to ventilate the tunnels and prevent the build-up of carbon monoxide.The original upper level of the George Washington Bridge and the first tube of the Lincoln Tunnel followed in the 1930s. Both crossings were later expanded to accommodate extra traffic: the Lincoln Tunnel in the 1940s and 1950s, and the George Washington Bridge in the 1960s. In 1955, the original Tappan Zee Bridge was built over one of the widest parts of the river, from Tarrytown to Nyack.
The late 20th century saw a decline in industrial production in the Hudson Valley. In 1993, IBM closed two of its plants in East Fishkill and Kingston due to IBM losing $16 billion over the previous three years. The plant in East Fishkill had 16,300 workers at its peak in 1984, and had opened in 1941 originally as part of the war effort. In 1996, the North Tarrytown GM Plant closed. In response to the plant closures, towns throughout the region sought to make the region attractive for technology companies. IBM maintained a Poughkeepsie mainframe unit, and newer housing and office developments were built near there as well. Commuting from Poughkeepsie to New York City also increased. Developers also looked to build on the property of the old GM plant.
Around the time of the last factories' closing, environmental efforts to clean up the river progressed. For example, GE participated in cleanup efforts to remove PCBs from the site of its old factory in Hudson Falls. The cleanup is part of an EPA Superfund site, and consists of dredging a 40-mile stretch of the river the Troy Dam to Fort Edward in order to remove the probable carcinogen from the ecosystem.Other conservation efforts also occurred, such as when Christopher Swain became the first person to swim all 315 miles of the Hudson River in support of cleaning it up.
In conjunction with conservation efforts, the Hudson River region has seen an economic revitalization, especially in favor of green development. In 2009, the High Line was opened in the Chelsea neighborhood of Manhattan. This linear park has views of the river throughout its length.Also in 2009, the original Poughkeepsie railroad bridge, since abandoned, was converted into the Walkway Over the Hudson, a pedestrian park over the river. Emblematic of the increase in green development in the region, waterfront parks in cities like Kingston, Poughkeepsie, and Beacon were built, and several festivals are held annually.
Numerous places have been constructed along the Hudson that have since become landmarks. Following the river from its source to mouth, there is the Hudson River Islands State Park in Greene and Columbia counties, and in Dutchess County, there is Bard College, Staatsburgh, the Vanderbilt Mansion National Historic Site, Franklin D. Roosevelt's home and presidential library, and the main campus of the Culinary Institute of America, Marist College, the Walkway over the Hudson, Bannerman's Castle, and Hudson Highlands State Park. South of that in Orange County is the United States Military Academy. In Westchester lies Indian Point Energy Center, Croton Point Park, and Sing Sing Correctional Facility.
In New Jersey is Stevens Institute of Technology and Liberty State Park. In Manhattan is Fort Tryon Park with the Cloisters, and the World Trade Center. Ellis Island, partially belonging to both the states of New Jersey and New York, is located just south of the river's mouth in New York Harbor. The Statue of Liberty, located on Liberty Island, is located a bit further south of there.
A 30-mile (48 km) stretch on the east bank of the Hudson has been designated the Hudson River Historic District, a National Historic Landmark. The Palisades Interstate Park Commission protects the Palisades on the west bank of the river. The Hudson River was designated as an American Heritage River in 1997. The Hudson River estuary system is part of the National Estuarine Research Reserve System as the Hudson River National Estuarine Research Reserve.
The Hudson River is navigable by large steamers up to Troy, and by ocean-faring vessels to the Port of Albany. 11 The original Erie Canal, opened in 1825 to connect the Hudson with Lake Erie, emptied into the Hudson at the Albany Basin, just 3 miles (4.8 km) south of the Federal Dam in Troy (at mile 134). The canal enabled shipping between cities on the Great Lakes and Europe via the Atlantic Ocean. The New York State Canal System, the successor to the Erie Canal, runs into the Hudson River north of Troy. It also uses the Federal Dam as a lock.:
Along the east side of the river runs the Metro-North Railroad's Hudson Line, from Manhattan to Poughkeepsie.The tracks continue north of Poughkeepsie as Amtrak trains run further north to Albany. On the west side of the river, CSX Transportation operates a freight rail line between North Bergen Yard in North Bergen, New Jersey and Selkirk Yard in Selkirk, New York.
The Hudson is crossed at numerous points by bridges, tunnels, and ferries. The width of the Lower Hudson River required major feats of engineering to cross; the results are today visible in the George Washington Bridge and the 1955 Tappan Zee Bridge (replaced by the New Tappan Zee Bridge) as well as the Lincoln and Holland Tunnels and the PATH and Pennsylvania Railroad tubes. The George Washington Bridge, which carries multiple highways, connects Fort Lee, New Jersey to the Washington Heights neighborhood of Upper Manhattan, and is the world's busiest motor vehicle bridge.The new Tappan Zee Bridge is the longest in New York, although the Verrazzano-Narrows Bridge has a larger main span. The Troy Union Bridge between Waterford and Troy was the first bridge over the Hudson; built in 1804 and destroyed in 1909; its replacement, the Troy–Waterford Bridge, was built in 1909. The Rensselaer and Saratoga Railroad was chartered in 1832 and opened in 1835, including the Green Island Bridge, the second bridge over the Hudson south of the Federal Dam.
The Hudson River's sediments contain a significant array of pollutants, accumulated over decades from industrial waste discharges, sewage treatment plants, and urban runoff. The overall water quality in the river has improved significantly since the 1990s, however.
The most discussed pollution of the Hudson River is General Electric's contamination of the river with polychlorinated biphenyls (PCBs) between 1947 and 1977.This pollution caused a range of harmful effects to wildlife and people who ate fish from the river or drank the water. In response to this contamination, activists protested in various ways. A group of fishermen formed an organization in 1966 that would later become Riverkeeper, the first member of the Waterkeeper Alliance. Musician Pete Seeger founded the Hudson River Sloop Clearwater and the Clearwater Festival to draw attention to the problem. Environmental activism led to passage of the federal Clean Water Act in 1972 as well as federal government designation of the river as a Superfund site in 1984. Other kinds of pollution, including mercury contamination and sewage dumping, have also caused problems.
Extensive remediation actions on the river began in the 1970s with the implementation of wastewater discharge permits and consequent control or reduction of wastewater discharges, and sediment removal operations, which have continued into the 21st century.
Zooplankton are abundant throughout the fresh and saltwater portions of the river, and provide a crucial food source for larval and juvenile fish.
The benthic zone has species capable of living in soft bottom habitats. Within freshwater regions, there are animal species including larvae of chironomid flies, oligochaete worms, predatory fly larvae, and amphipods. In saline regions, there are abundant polychaete annelids, amphipods, and some mollusks such as clams. These species burrow in the sediment and accelerate the breakdown of organic matter. Atlantic blue crabs are among the larger invertebrates, at the northern limit of their range. The entire Hudson was once far more populated with native suspension-feeding bivalves. Freshwater mussels were common in the river's limnetic zone, but populations have been decreasing for decades, probably from altered habitats and the invasive zebra mussel. Oyster beds were once pervasive in the saltwater portion, but are now reduced through pollution and exploitation.
According to the NYSDEC Hudson River Estuary Program, about 220 species of fish, including 173 native species, currently are found in the Hudson River.Commercial fishing was once prominent in the river, although most were shut down in 1976 due to pollution; few survive today. American shad are the only finfish harvested for profit, though in limited numbers.
Species include striped bass, the most important game fish in the Hudson. Estimates of the striped bass population in the Hudson range to nearly 100 million fish.American eels also live in the river before reaching breeding age; for much of this stage they are known as glass eels because of the transparency of their bodies. The fish are the only catadromous species in the Hudson's estuary.
The Atlantic tomcod is a unique species that adapted resistance to the toxic effects of the PCBs polluting the river. Scientists identified the genetic mutation that conferred the resistance, and found that the mutated form was present in 99 percent of the tomcods in the river, compared to fewer than 10 percent of the tomcods from other waters.The hogchoker flatfish have been historically abundant in the river, where farmers would use them for inexpensive livestock feed, giving the fish its name. Other unusual fish found in the river include the northern pipefish, the lined seahorse, and the northern puffer.
The Atlantic sturgeon, a species about 120 million years old, enter the estuary during their annual migrations. The fish grow to a considerable size, up to 15 feet (4.6 m) and 800 pounds (360 kg). The fish are the symbol of the Hudson River Estuary. Their smoked flesh was commonly eaten in the river valley since 1779, and it was sometimes known as "Albany beef". The city of Albany was called "Sturgeondom" or "Sturgeontown" in the 1850s and 1860s, with its residents known as "Sturgeonites". The "Sturgeondom" name lost popularity around 1900. The fish have been off limits from fishing since 1998. The river's population of shortnose sturgeon have quadrupled since the 1970s, and are also off limits to all fishing as they are a federally endangered species.
Marine life is known to exist in the estuary, with seals, crabs, and some whales reported. On March 29, 1647, a white whale swam up the river to the Rensselaerswyck (near Albany). Herman Melville, author of Moby-Dick , lived in and near Albany from 1830 to 1847, and was known to have ancestry from New Netherland, leading some to believe stories of the whale sighting inspired his novel.
Non-native species often originate in New York Harbor, a center of long-distance commerce. Over 100 foreign species reside in the river and its banks. Many of these have had significant effects on the ecosystem and natural habitats. The water chestnut produces a vegetative mat that reduces oxygen content in the water below, enhances sedimentation, impedes small vessel navigation, and is a hazard to swimmers and walkers. The zebra mussel arrived in the Hudson in 1989 and has spread through the river's freshwater region, reducing photoplankton and river oxygen levels. Positively, the mussel clears suspended particles, allowing for more light to aquatic vegetation. In saltwater areas, the green crab spread in the early 20th century and the Japanese shore crab has become dominant in recent years.
The Hudson has a diverse array of habitat types. Most of the river consists of deep water habitats, though its tidal wetlands of freshwater and salt marshes are among the most ecologically important. There is strong biological diversity, including intertidal vegetation like freshwater cattails and saltwater cordgrasses. Shallow coves and bays are often covered with submarine vegetation; shallower areas harbor diverse benthic fauna. Abundance of food varies over location and time, stemming from seasonal flows of nutrients. The Hudson's large volume of suspended sediments reduces light penetration in the area's water column, which reduces photoplankton photosynthesis and prevents sub-aquatic vegetation from growing beyond shallow depths. The oxygen-producing phytoplankton have also been inhibited by the relatively recent invasion of the zebra mussel species.
The Hudson River estuary is the site of wetlands from New York City all the way up to Troy. It has one of the largest concentrations of freshwater wetlands in the Northeast. Even though the river can be considered brackish further south, 80 percent of the wetlands are outside the influence of the saltwater coming from the Atlantic Ocean. Currently, the river has about 7,000 acres (28 km2) acres of wetlands, and rising sea levels due to climate change are expected to lead to an expansion of that area. Wetlands are expected to migrate upland as sea level (and thus the level of the river) rises. This is different from the rest of the world, where rising sea levels usually leads to a reduction in wetland areas. The expansion of the wetlands are expected to provide more habitat to the fish and birds of the region.
Parkland surrounds much of the Hudson River; prominent parks include Battery Park and Liberty State Park at the river's mouth,Riverside Park in Manhattan, Croton Point Park, Bear Mountain State Park, Storm King State Park and the Hudson Highlands, Moreau Lake State Park, and its source in the High Peaks Wilderness Area.
Fishing is allowed in the river, although the state Department of Health recommends eating no fish caught from the South Glens Falls Dam to the Federal Dam at Troy. Women under 50 and children under 15 are not advised to eat any fish caught south of the Palmer Falls Dam in Corinth, while others are advised to eat anywhere from one to four meals per month of Hudson River fish, depending on species and location caught. The Department of Health cites mercury, PCBs, dioxin, and cadmium as the chemicals impacting fish in these areas.
Common native species recreationally fished include striped bass (formerly a major commercial species, now only legally taken by anglers), channel catfish, white catfish, brown bullhead, yellow perch, and white perch. The nonnative largemouth and smallmouth bass are also popular, and serve as the focus of catch-and-release fishing tournaments.
The Erie Canal is a canal in New York, United States that is part of the east–west, cross-state route of the New York State Canal System. Originally, it ran 363 miles (584 km) from the Hudson River in Albany to Lake Erie in Buffalo. It was built to create a navigable water route from New York City and the Atlantic Ocean to the Great Lakes. When completed in 1825, it was the second longest canal in the world and greatly enhanced the development and economy of New York, New York City, and the United States.
U.S. Route 9 is a north–south United States highway in the states of Delaware, New Jersey, and New York in the United States. It is one of only two U.S. Highways with a ferry connection ; the other is US 10. US 9 is signed east–west in Delaware and north–south on the rest of its route. The western terminus of the route is in Laurel, Delaware, at an intersection with U.S. Route 13, while the highway's northern terminus is at a junction with Interstate 87 (I-87) in Champlain, New York, where the roadway continues north as the unsigned NY 971B, which ends in a cul-de-sac just short of the Canada–US border.
Interstate 87 (I-87) is a 333.49-mile-long (536.70 km) north–south intrastate Interstate Highway located within the U.S. state of New York, and is most of the main highway between New York City and Montreal. The highway begins at exit 47 off I-278 in the New York City borough of the Bronx, just north of the Triborough Bridge and Grand Central Parkway. From there, the route runs northward through the Hudson Valley, the Capital District, and the easternmost part of the North Country to the Canadian border in the Town of Champlain. At its north end, I-87 continues into Quebec as Autoroute 15 (A-15). I-87 connects with several regionally important roads: I-95 in New York City, New York State Route 17 near Harriman, I-84 near Newburgh, and I-90 in Albany. The route is the longest intrastate Interstate Highway in the Interstate Highway System. The highway is not contiguous with I-87 in North Carolina.
Poughkeepsie is a city in the state of New York. It is the county seat of Dutchess County with a 2018 census-estimated population of 30,356. Poughkeepsie is in the Hudson River Valley region, midway between the core of the New York metropolitan area and the state capital of Albany. It is a principal city of the Poughkeepsie–Newburgh–Middletown metropolitan area which belongs to the New York metropolitan area. It is served by the nearby Hudson Valley Regional Airport and Stewart International Airport in Orange County, New York.
The New York Central Railroad was a railroad primarily operating in the Great Lakes and Mid Atlantic regions of the United States. The railroad primarily connected greater New York and Boston in the east with Chicago and St. Louis in the Midwest along with the intermediate cities of Albany, Buffalo, Cleveland, Cincinnati, Detroit, and Syracuse. New York Central was headquartered in New York City's New York Central Building, adjacent to its largest station, Grand Central Terminal.
North River is an alternative name for the southernmost portion of the Hudson River in the vicinity of New York City and northeastern New Jersey in the United States. The entire watercourse was known as the North River by the Dutch in the early seventeenth century; the term fell out of general use for most of the river's 300+ mile course during the early 1900s. However the name remains in very limited use as an artifact among history-inclined local mariners and others and on some nautical charts and maps. The term is also used for infrastructure on and under the river, such as the North River piers, North River Tunnels, and the North River Wastewater Treatment Plant.
The Hudson Valley comprises the valley of the Hudson River and its adjacent communities in the U.S. state of New York. The region stretches from the Capital District including Albany and Troy south to Yonkers in Westchester County, bordering New York City.
Upstate New York is the portion of the American state of New York lying north of the New York metropolitan area. The Upstate region includes most of the land area of the state of New York, but a minority of the state's population. Although the precise boundary is debated, Upstate New York excludes New York City and Long Island, and most definitions of the region exclude all or part of Westchester and Rockland counties. Major cities in Upstate New York, from east to west, include Albany, Utica, Binghamton, Syracuse, Rochester, and Buffalo.
The Capital District, also known as the Capital Region, is the metropolitan area surrounding Albany, the capital of the U.S. state of New York. In the 21st century, the Capital District emerged as a major anchor of Tech Valley, the moniker describing the technologically-focused region of eastern New York State. The Capital District was first settled by the Dutch in the early 17th century and came under English control in 1664. Albany has been the permanent capital of the state of New York since 1797. The Capital District is notable for many historical events that predate the independence of the United States, including the Albany Plan of Union and The Battles of Saratoga. Part of the Northern Capital District also covers the southern portion of the Adirondack Mountains.
The Hackensack River is a river, approximately 45 miles (72 km) long, in the U.S. states of New York and New Jersey, emptying into Newark Bay, a back chamber of New York Harbor. The watershed of the river includes part of the suburban area outside New York City just west of the lower Hudson River, which it roughly parallels, separated from it by the New Jersey Palisades. It also flows through and drains the New Jersey Meadowlands. The lower river, which is navigable as far as the city of Hackensack, is heavily industrialized and forms a commercial extension of Newark Bay. Once believed to be among the most polluted water courses in the United States, it staged a modest revival by the late 2000s.
Area codes 518 and 838 are telephone area codes serving the easternmost part of Upstate New York in the United States. 518 was established as one of the original area codes in 1947. 838 was added as an overlay in 2017. It covers 24 counties and 1,200 ZIP Codes. It has 493 landline and 100 wireless exchanges serviced by 47 carriers. It is the largest area code in size in New York, extending from the eastern Mohawk Valley to the Vermont border, and from the Canada–US border to south of Albany. The bulk of the area code's population is in the Capital District. Other major cities in the area code are Glens Falls, Plattsburgh, and Saratoga Springs.
Metro-North Railroad's Hudson Line is a commuter rail line running north from New York City along the east shore of the Hudson River. Metro-North service ends at Poughkeepsie, with Amtrak's Empire Corridor trains continuing north to and beyond Albany. The line was originally the Hudson River Railroad, and eventually became the Hudson Division of the New York Central Railroad, part of the Central's famed Water Level Route.
The Walkway over the Hudson is a steel cantilever bridge spanning the Hudson River between Poughkeepsie, New York, on the east bank and Highland, New York, on the west bank. Built as a double track railroad bridge, it was completed on January 1, 1889, and formed part of the Maybrook Railroad Line of the New Haven Railroad.
The Port of New York and New Jersey is the port district of the New York-Newark metropolitan area, encompassing the region within approximately a 25-mile (40 km) radius of the Statue of Liberty National Monument. It includes the system of navigable waterways in the New York–New Jersey Harbor Estuary, which runs along 650 miles (1,050 km) of shoreline in the vicinity of New York City and northeastern New Jersey, as well as the region's airports and supporting rail and roadway distribution networks. Considered one of the largest natural harbors in the world, the port is by tonnage the third largest in the United States and the busiest on the East Coast.
U.S. Route 9 (US 9) is a part of the U.S. Highway System that runs from Laurel, Delaware, to Champlain, New York. In New York, US 9 extends 324.72 miles (522.59 km) from the George Washington Bridge in Manhattan to an interchange with Interstate 87 (I-87) just south of the Canada–United States border in the town of Champlain. US 9 is the longest north–south U.S. Highway in New York; additionally, the portion of US 9 in New York accounts for more than half of the highway's total length.
The Amtrak Hudson Line, also known as the CSX Hudson Subdivision, is a railroad line owned by CSX Transportation and leased by Amtrak in the U.S. state of New York. The line runs from Poughkeepsie north along the east shore of the Hudson River to Rensselaer and northwest to Hoffmans via Albany and Schenectady along a former New York Central Railroad line. From its south end, CSX has trackage rights south to New York City along the Metro-North Railroad's Hudson Line. The Hudson Line junctions the Castleton Subdivision in Stuyvesant, Amtrak's Post Road Branch in Rensselaer, and the Carman Subdivision in Schenectady. Its northwest end is at a merge with the Mohawk Subdivision.
The Port of Albany–Rensselaer, widely known as the Port of Albany, is a port of entry in the United States with facilities on both sides of the Hudson River in Albany and Rensselaer, New York. Private and public port facilities have existed in both cities since the 17th century, with an increase in shipping after the Albany Basin and Erie Canal were built with public funds in 1825.
The Hudson River is a 315-mile (507 km) river in New York. The river is named after Henry Hudson, an Englishman sailing for the Dutch East India Company, who explored it in 1609, and after whom Canada's Hudson Bay is also named. It had previously been observed by Italian explorer Giovanni da Verrazzano sailing for King Francis I of France in 1524, as he became the first European known to have entered the Upper New York Bay, but he considered the river to be an estuary. The Dutch called the river the North River – with the Delaware River called the South River – and it formed the spine of the Dutch colony of New Netherland. Settlements of the colony clustered around the Hudson, and its strategic importance as the gateway to the American interior led to years of competition between the English and the Dutch over control of the river and colony.
The Hudson Valley comprises the valley of the Hudson River and its adjacent communities in the U.S. state of New York, from the cities of Albany and Troy southward to Yonkers in Westchester County. Depending upon the definition delineating its boundaries, the Hudson Valley encompasses a growing metropolis which is home to between 3 and 3.5 million residents centered along the north-south axis of the Hudson River.
