Unity Pond (Lake Winnecook) is the largest lake in Waldo County, Maine. It is within the towns of Unity, Burnham, and Troy. The main tributaries are Meadow Brook, Bithers Brook, and Carlton Stream. [1] The sole outflow is Twenty-Five Mile Stream, via a wetlands to the southwest of the lake, which in turn feeds into the Sebasticook River. The lake is surrounded by almost 300 residences, of which slightly more than half are seasonal. [1] It is also used for boating, fishing, camping, and swimming. Kanokolus Beach on the southwest shore and Burnham Town Beach are both open to the public. [1]
Europeans first settled Unity Pond in 1785. [3] By the early 1800s, sawmills were established along the three main tributaries to the lake. By 1830, however, deforestation caused most of the sawmills to close. [3] Deforestation made agriculture possible, which continued in the lands adjoining the lake well into the 20th century. Canneries were established in the area from the 1920s to the 1950s. As subsistence agriculture declined in the 1940s, it was replaced by poultry and dairy farming, [1] and seasonal camps were built along the lake shore. [3]
The lake has been subject to eutrophication caused historically by agricultural runoff and effluent from a canning factory, and is on the state Nonpoint Source Priority Watersheds list, owing to the occurrence of summer algal blooms caused by phosphorus nutrient addition by runoff water. [1] The watershed area surrounding the pond consists of 16.2% developed land, 71.7% non-developed land (consisting mostly of forest), and 12.1% surface water. [1] A total of 20 fish species are found in the lake, including 12 indigenous species. The lake is stocked with trout and alewife. [1]
Columbia is a town in Washington County, Maine, United States. The population was 486 at the 2010 census. According to the United States Census Bureau, the town has a total area of 36.61 square miles (94.82 km2), of which, 36.30 square miles (94.02 km2) of it is land and 0.31 square miles (0.80 km2) is water.
Fishkill Creek is a tributary of the Hudson River in Dutchess County, New York, United States. At 33.5 miles (53.9 km) it is the second longest stream in the county, after Wappinger Creek. It rises in the town of Union Vale and flows generally southwest to a small estuary on the Hudson just south of Beacon. Part of its 193-square-mile (500 km2) watershed is in Putnam County to the south. Sprout Creek, the county's third-longest creek, is its most significant tributary. Whaley and Sylvan lakes and Beacon Reservoir, its largest, deepest and highest lakes, are among the bodies of water within the watershed.
Wreck Pond is a coastal freshwater tidal pond located on the coast of the Atlantic Ocean in Monmouth County, New Jersey, United States. It is surrounded by Wall Township and the boroughs of Spring Lake, Spring Lake Heights, and Sea Girt. The pond was originally connected to the sea by a small inlet and got its name because sailors would mistake it, in the dark, for the Manasquan Inlet, which is further south. This was alleviated by the building of the Sea Girt Lighthouse and stopped by the eventual filling in of the inlet.
San Juan Creek, also called the San Juan River, is a 29-mile (47 km) long stream in Orange and Riverside Counties, draining a watershed of 133.9 square miles (347 km2). Its mainstem begins in the southern Santa Ana Mountains in the Cleveland National Forest. It winds west and south through San Juan Canyon, and is joined by Arroyo Trabuco as it passes through San Juan Capistrano. It flows into the Pacific Ocean at Doheny State Beach. San Juan Canyon provides a major part of the route for California State Route 74.
A stream is a body of water with surface water flowing within the bed and banks of a channel. The flow of a stream is controlled by three inputs – surface water, subsurface water and groundwater. The surface and subsurface water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls.
The Fish River is a 69.9-mile-long (112.5 km) river in northern Maine in the United States. It is a tributary of the Saint John River, which flows to the Bay of Fundy in New Brunswick, Canada.
The Moose River is an 83-mile-long (134 km) river in Maine. Its source is in Beattie, on the Canada–United States border, which runs along the height of land between the watersheds of the Kennebec River in Maine and the Chaudière River in Quebec. From there, the river runs east through Attean Pond and Wood Pond, past the town of Moose River, then through Long Pond and Brassua Lake. The Moose River empties into Moosehead Lake, the source of the Kennebec River, in Rockwood Strip. The International Railway of Maine was built along Moose River in 1889.
The Pleasant River is a 13.1-mile-long (21.1 km) tributary of the Presumpscot River in the U.S. state of Maine.
The Sebec River is a tributary of the Piscataquis River in Piscataquis County, Maine. From the outflow of Sebec Lake in Sebec, the river runs 10.0 miles (16.1 km) east and southeast to its confluence with the Piscataquis in Milo.
Harris Station Dam is a hydroelectric dam in Northeast Somerset, Somerset County, Maine. Also known as the Indian Pond Project, the dam was built from 1952 to 1954 as the largest hydroelectric dam in the state of Maine. It impounds the Kennebec River at the southern end of the natural Indian Pond, about 12 miles downstream from Moosehead Lake.
Enchanted Pond is a mountain pond in the U.S. state of Maine. Situated in the Western Maine Mountains in the Northwest Somerset Region, the pond is located in a deep mountain valley between Coburn Mountain and Shutdown Mountain. Near its southern end, the pond is distinguished by two rockslides from the exposed cliffs of these mountains that extend down into the water along both shores. Enchanted Pond is fed by mountain springs and Little Enchanted Pond, and is the primary source of Enchanted Stream which flows into the Dead River, a tributary of the Kennebec River. Development on the pond is limited to a small set of sporting camps at the northern end of the pond and one remote camp on the southwest shore, both a part of Bulldog Camps. There are no islands in the pond.
The West Branch Lackawanna River is a tributary of the Lackawanna River in Susquehanna County, Pennsylvania, in the United States. It is approximately 9.5 miles (15.3 km) long and flows through Ararat Township, Herrick Township, and Union Dale. The watershed of the river has an area of 16.8 square miles (44 km2). The river is not designated as an impaired stream and it has a high level of water quality. Lakes and wetlands in the river's watershed include Ball Lake, Fiddle Lake, Hathaway Lake, Lake Romobe, Lewis Lake, Lowe Lake, and Sink Hole Swamp. The river is also dammed by at least two dams: the Romobe Lake Dam and the Hathaway Pond Dam.
The Sebasticook Lake Fishweir Complex is a series of prehistoric fishing weir structures submerged in the waters of Sebasticook Lake in Newport, Maine. With radiocarbon dates as far back as 3000 BCE, it is one of the oldest structures of its type in North America, and the only one in eastern North America that has been directly dated. Its existence provides evidence of large-scale organization among Native Americans of the period in northeastern North America necessary to create structures of its complexity. The complex was listed on the National Register of Historic Places in 1994.
Chamberlain Lake is one of the largest and deepest lakes in the North Maine Woods. The lake originally drained north through Eagle Lake and Churchill Lake into the Allagash River tributary to the Saint John River. Nineteenth-century logging operations diverted the lake into the Penobscot River before designation of the Allagash Wilderness Waterway in 1966.
Caucomgomoc Lake is in the North Maine Woods at the corner of townships 6 and 7 in ranges 14 and 15. Loon Stream flows into the southern end of the lake from Loon Lake, Bear Pond, Big Hurd Pond, Little Hurd Pond, Bear Brook Pond, McDougal Pond, and tributaries from the southwest. Overflow from Little Shallow Lake through Shallow Lake, Daggett Pond, and Round Pond enters the east side of Caucomgomoc Lake through Ciss Stream. Smaller tributaries Avery Brook, Middle Brook, and Ramsell Brook flow into the north end of the lake. There is a dam at the lake outlet on the eastern shore a short distance south of Ciss Stream. Discharge through the dam flows down Caucomgomoc Stream through Black Pond and Chesuncook Lake to the West Branch Penobscot River at Ripogenus Gorge. White perch and yellow perch have largely replaced historic trout populations in the lake.
The Fish River chain of lakes is a series of five lakes in the North Maine Woods region of northern Maine, in a tributary stream to the Fish River. The lakes are an important northern Maine recreation area providing habitat for wildlife including rainbow smelt, brook trout, lake trout, and land-locked Atlantic salmon.
The Belgrade Lakes are a chain of lakes around Belgrade, Maine. The flow sequence is from East Pond to North Pond to Great Pond to Long Pond to Messalonskee Lake and thence via Messalonskee Stream to the Kennebec River at Waterville. The lakes have long been an important resort area for fishing, boating, and swimming; and shoreline development includes residences for individuals employed in the cities of Waterville and Augusta.
Hancock Brook is an east-bank tributary to the Saco River at Hiram, Maine. The brook originates in eastern Denmark and flows through a chain of ponds along the border between Hiram and Sebago. The narrow-gauge Bridgton and Saco River Railroad was built along the brook in 1882, and operated until 1941.
The Saint John Ponds are a chain of shallow lakes at the headwaters of the Baker Branch Saint John River in the North Maine Woods. The flow sequence is from the Upper First Saint John Pond, through the Lower First Saint John Pond, Second Saint John Pond, Third Saint John Pond, and Fourth Saint John Pond to the Fifth Saint John Pond. Flow from one pond to the next is sometimes called Baker Stream rather than the Baker Branch Saint John River. Great Northern Paper Company dug a canal from Fifth Saint John Pond 2 miles (3.2 km) eastward to the North Branch Penobscot River in 1939, and built a dam at the north end of Fifth Saint John Pond so pulpwood logs harvested in the upper Saint John River watershed could be floated down the Penobscot River to Millinocket, Maine. The canal and dam have fallen into disrepair so most drainage from the ponds again flows down the Saint John River. All upstream ponds with the exception of the first had dams to regulate discharge flow for log driving, but those dams have similarly fallen into disrepair. Moose use the ponds as summer refuge from heat and biting insects.
The Depot River is a tributary of the Big Black River, flowing in the townships T12 R17 Wels, T13 R16 Wels and T14 R15 Wels, in the Aroostook County in North Maine Woods in Maine, in United States.
