Lake Havasu is a large reservoir formed by Parker Dam on the Colorado River, on the border between California and Arizona. Lake Havasu City sits on the lake's eastern shore. The reservoir has an available capacity of 619,400 acre feet (764,000,000 m3). The concrete arch dam was built by the United States Bureau of Reclamation between 1934 and 1938. The lake's primary purpose is to store water for pumping into two aqueducts. Prior to the dam construction, the area was home to the Mohave Indians. The lake was named (in 1939) after the Mojave word for blue. In the early 19th century, it was frequented by beaver trappers.[ citation needed ] Spaniards also began to mine the areas along the river.[ citation needed ]
A reservoir is, most commonly, an enlarged natural or artificial lake, pond or impoundment created using a dam or lock to store water.
Parker Dam is a concrete arch-gravity dam that crosses the Colorado River 155 miles (249 km) downstream of Hoover Dam. Built between 1934 and 1938 by the Bureau of Reclamation, it is 320 feet (98 m) high, 235 feet (72 m) of which are below the riverbed, making it the deepest dam in the world. The dam's primary functions are to create a reservoir, and to generate hydroelectric power. The reservoir behind the dam is called Lake Havasu and can store 647,000 acre⋅ft (798,000,000 m3) or over 210 billion US gallons. The dam straddles the state border at the narrows the river passes through between the Whipple Mountains of California and the Buckskin Mountains of Arizona.
The Colorado River is one of the principal rivers in the Southwestern United States and northern Mexico. The 1,450-mile-long (2,330 km) river drains an expansive, arid watershed that encompasses parts of seven U.S. and two Mexican states. Starting in the central Rocky Mountains of Colorado, the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.
Mark Wilmer Pumping Plant pumps water into the Central Arizona Project Aqueduct. Whitsett Pumping Plant is located on the lake, and lifts the water 291 feet (89 m) for the Colorado River Aqueduct. Gene Pumping Plant is just south of Parker Dam, and gives the water an additional boost of 303 feet (92 m). The Colorado River Aqueduct has three more pumping plants: Iron Mountain (144 feet (44 m)), Eagle Mountain (438 feet (134 m)), and Julian Hinds (441 feet (134 m)). The total lift is 1,617 feet (493 m).
The Colorado River Aqueduct, or CRA, is a 242 mi (389 km) water conveyance in Southern California in the United States, operated by the Metropolitan Water District of Southern California (MWD). The aqueduct impounds water from the Colorado River at Lake Havasu on the California-Arizona border west across the Mojave and Colorado deserts to the east side of the Santa Ana Mountains. It is one of the primary sources of drinking water for Southern California.
The shorelines are in the ecotone (transition zone) of the higher Mojave Desert to the lower Sonoran Desert and its Californian Colorado Desert ecoregions.
An ecotone is a transition area between two biomes. It is where two communities meet and integrate. It may be narrow or wide, and it may be local or regional. An ecotone may appear on the ground as a gradual blending of the two communities across a broad area, or it may manifest itself as a sharp boundary line.
The Mojave Desert is an arid rain-shadow desert and the driest desert in North America. It is in the North American Southwest, primarily within southeastern California and southern Nevada, and it occupies 47,877 sq mi (124,000 km2). Very small areas also extend into Utah and Arizona. Its boundaries are generally noted by the presence of Joshua trees, which are native only to the Mojave Desert and are considered an indicator species, and it is believed to support an additional 1,750 to 2,000 species of plants. The central part of the desert is sparsely populated, while its peripheries support large communities such as Las Vegas, Barstow, Lancaster, Palmdale, Victorville, and St. George.
The Sonoran Desert is a North American desert which covers large parts of the Southwestern United States in Arizona and California and of Northwestern Mexico in Sonora, Baja California, and Baja California Sur. It is the hottest desert in Mexico. It has an area of 260,000 square kilometers (100,000 sq mi). The western portion of the United States–Mexico border passes through the Sonoran Desert.
The Havasu National Wildlife Refuge is located at the upper end and upriver. Lake Havasu State Park is along the eastern shore in Arizona. The Bill Williams River National Wildlife Refuge extends southeastward up the riparian zone of the Bill Williams River canyon from the southeastern end of the reservoir and dam.
Havasu National Wildlife Refuge is a U.S. National Wildlife Refuge on the lower Colorado River in Arizona and California. It preserves habitat for desert bighorn sheep to the endangered southwestern willow flycatcher, birds and other animals. The refuge protects 30 river miles - 300 miles (480 km) of shoreline - from Needles, California, to Lake Havasu City, Arizona. One of the last remaining natural stretches of the lower Colorado River flows through the 20-mile-long (32 km) Topock Gorge.
Lake Havasu State Park is a state park located on Lake Havasu in Mohave County, Arizona, USA. The park provides outdoor recreation opportunities such as camping, boating, and fishing. The Arroyo-Camino Interpretive Garden displays local desert flora.
The Bill Williams River National Wildlife Refuge protects the lower course of the Bill Williams River, to its mouth at Lake Havasu reservoir, in western Arizona. It is located within eastern La Paz and Mohave Counties, in the Lower Colorado River Valley region.
Lake Havasu is well known for its recreational fishing and boating, which bring in around 750,000 visitors a year.Fishing tournaments are often held on the lake, where bass are the main catch.
Bass is a name shared by many species of fish. The term encompasses both freshwater and marine species, all belonging to the large order Perciformes, or perch-like fishes. The word bass comes from Middle English bars, meaning "perch".
Fish list : Largemouth bass, Smallmouth bass, Striped bass, Carp, Catfish (Channel), Catfish (Flathead), Crappie, Razorback sucker, Redear Sunfish, Sunfish (Cetrarchidae).
The largemouth bass is a carnivorous freshwater gamefish in the Centrarchidae (sunfish) family, a species of black bass native to the eastern and central United States and northern Mexico, but widely introduced elsewhere. It is known by a variety of regional names, such as the widemouth bass, bigmouth bass, black bass, bucketmouth, largies, Potter's fish, Florida bass, Florida largemouth, green bass, bucketmouth bass, Green trout, gilsdorf bass, Oswego bass, southern largemouth and (paradoxically) northern largemouth, LMB. The largemouth bass is the state fish of Georgia and Mississippi, and the state freshwater fish of Florida and Alabama.
The smallmouth bass is a species of freshwater fish in the sunfish family (Centrarchidae) of the order Perciformes. It is the type species of its genus. One of the black basses, it is a popular game fish sought by anglers throughout the temperate zones of North America, and has been spread by stocking—as well as illegal introductions—to many cool-water tributaries and lakes in Canada and more so introduced in the United States. The maximum recorded size is approximately 27 inches and 12 pounds. The smallmouth bass is native to the upper and middle Mississippi River basin, the Saint Lawrence River–Great Lakes system, and up into the Hudson Bay basin. Its common names include smallmouth, bronzeback, brown bass, brownie, smallie, bronze bass, and bareback bass.
The striped bass, also called Atlantic striped bass, striper, linesider, rock or rockfish, is an anadromous Perciforme fish of the family Moronidae found primarily along the Atlantic coast of North America. It has also been widely introduced into inland recreational fisheries across the United States. Striped bass found in the Gulf of Mexico are a separate strain referred to as Gulf Coast striped bass.
White sturgeon were stocked in Lake Havasu in 1967 and 1968 from stock obtained from San Pablo Bay, California. While some dead sturgeon were found downstream from Havasu (probably killed during passage over dams), living fish have not been recorded, but may still exist along the southern end of Lake Havasu near Parker Dam.Sturgeon have been known to grow upwards of 20 feet (6 meters) and can live in excess of 100 years and many in and around Lake Havasu continue in their efforts to catch a glimpse of the majestic animal.
The California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for Lake Havasu based on levels of mercury found in fish caught from this water body.
Robert Paxton McCulloch was an American entrepreneur most notable for purchasing the old London Bridge and moving it to one of the cities he founded in Arizona. Lake Havasu sparked the imagination of McCulloch, who purchased 3,500 acres (1,400 ha) of lakeside property along Pittsburgh Point, the peninsula that eventually would be transformed into "the island".
Lake Powell is a reservoir on the Colorado River, straddling the border between Utah and Arizona, United States. Most of Lake Powell, along with Rainbow Bridge National Monument, is located in Utah. It is a major vacation spot that around two million people visit every year. It is the second largest man-made reservoir by maximum water capacity in the United States behind Lake Mead, storing 24,322,000 acre feet (3.0001×1010 m3) of water when full. However, due to high water withdrawals for human and agricultural consumption, and because of subsequent droughts in the area, Lake Mead has fallen below Lake Powell in size several times during the 21st century in terms of volume of water, depth and surface area.
Pyramid Lake is a reservoir formed by Pyramid Dam on Piru Creek in the eastern San Emigdio Mountains, near Castaic, Southern California. It is a part of the West Branch California Aqueduct, which is a part of the California State Water Project. Its water is fed by the system after being pumped up from the San Joaquin Valley and through the Tehachapi Mountains.
Diamond Valley Lake is a man-made off-stream reservoir located near Hemet, California, United States. It is one of the largest reservoirs in Southern California and also one of the newest. With a capacity of 800,000 acre feet (990,000,000 m3), the lake nearly doubled the area’s surface water storage capacity and provides additional water supplies for drought, peak summer, and emergency needs.
The Metropolitan Water District of Southern California is a regional wholesaler and the largest supplier of treated water in the United States. The name is usually shortened to "Met," "Metropolitan," or "MWD." It is a cooperative of fourteen cities, eleven municipal water districts, and one county water authority, that provides water to 19 million people in a 5,200-square-mile (13,000 km2) service area. It was created by an act of the California Legislature in 1928, primarily to build and operate the Colorado River Aqueduct. Metropolitan became the first contractor to the State Water Project in 1960.
The San Luis Reservoir is an artificial lake on San Luis Creek in the eastern slopes of the Diablo Range of Merced County, California, approximately 12 mi (19 km) west of Los Banos on State Route 152, which crosses Pacheco Pass and runs along its north shore. It is the fifth largest reservoir in California. The reservoir stores water taken from the San Joaquin-Sacramento River Delta. Water is pumped uphill into the reservoir from the O'Neill Forebay which is fed by the California Aqueduct and is released back into the forebay to continue downstream along the aqueduct as needed for farm irrigation and other uses. Depending on water levels, the reservoir is approximately nine miles long from north to south at its longest point, and five miles (8 km) wide. At the eastern end of the reservoir is the San Luis Dam, or the B.F. Sisk Dam, the fourth largest embankment dam in the United States, which allows for a total capacity of 2,041,000 acre feet (2,518,000 dam3).
The New Waddell Dam is an embankment dam on the Agua Fria River in Maricopa County, Arizona, 35 miles (56 km) northwest of Phoenix. It serves as part of the Central Arizona Project (CAP) while also providing water for the Maricopa Water District. The dam creates Lake Pleasant with water from the Agua Fria and also the CAP aqueduct. In addition, it affords flood protection, hydroelectric power production and recreational opportunities. Construction on the dam began in 1985 and ended in 1994. Its reservoir submerged the Old Waddell Dam which was completed in 1927 after decades of planning.
The Laguna Diversion Dam is a rock-filled diversion dam on the Colorado River. It is located 13 miles northeast of Winterhaven, CA–Yuma, AZ on Imperial County route S24. Constructed between 1903 and 1905, the dam was the first dam built on the Colorado River and subsequently ended boat travel to the north.
Castaic Lake is a reservoir formed by Castaic Dam on Castaic Creek, in the Sierra Pelona Mountains of northwestern Los Angeles County, California, United States, near the town of Castaic.
Folsom Lake is a reservoir on the American River in the Sierra Nevada foothills of California, United States.
Silverwood Lake is a large reservoir in San Bernardino County, California, United States, located on the West Fork Mojave River, a tributary of the Mojave River in the San Bernardino Mountains. It was created in 1971 as part of the State Water Project by the construction of the Cedar Springs Dam as a forebay on the 444-mile (715 km) long California Aqueduct, and has a capacity of 73,000 acre feet (90,000,000 m3).
The Lower Colorado River Valley ("LCRV") is the river region of the lower Colorado River of the southwestern United States in North America that rises in the Rocky Mountains and has its outlet at the Colorado River Delta in the northern Gulf of California in northwestern Mexico, between the states of Baja California and Sonora. This north–south stretch of the Colorado River forms the border between the U.S. states of California/Arizona and Nevada/Arizona, and between the Mexican states of Baja California/Sonora.
The Imperial Reservoir is an artificial lake formed by the construction of the Imperial Diversion Dam across the Colorado River in the Lower Colorado River Valley of Imperial County, California, and Yuma County, Arizona. A component of the Imperial National Wildlife Refuge, the reservoir is 16 miles (26 km) northeast of Yuma, Arizona.
O'Neill Forebay is a forebay to the San Luis Reservoir created by the construction of O'Neill Dam across San Luis Creek approximately 12 miles (19 km) west of Los Banos, California, United States, on the eastern slopes of the Pacific Coast Ranges of Merced County.
Bridge Canyon Dam, also called Hualapai Dam, was a proposed dam in the lower Grand Canyon of the Colorado River, in northern Arizona in the United States. It would have been located near Bridge Canyon Rapids in an extremely rugged and isolated portion of the canyon, 235 miles (378 km) downstream of Lee's Ferry and at the uppermost end of Lake Mead.
The Colorado River is a major river of the western United States and northwest Mexico in North America. Its headwaters are in the Rocky Mountains where La Poudre Pass Lake is its source. Located in north central Colorado it flows southwest through the Colorado Plateau country of western Colorado, southeastern Utah and northwestern Arizona where it flows through the Grand Canyon. It turns south near Las Vegas, Nevada, forming the Arizona–Nevada border in Lake Mead and the Arizona–California border a few miles below Davis Dam between Laughlin, Nevada and Needles, California before entering Mexico in the Colorado Desert. Most of its waters are diverted into the Imperial Valley of Southern California. In Mexico its course forms the boundary between Sonora and Baja California before entering the Gulf of California. This article describes most of the major features along the river.
The Marble Canyon Dam, also known as the Redwall Dam, was a proposed dam on the Colorado River in Arizona. The dam was intended to impound a relatively small reservoir in the central portion of Marble Canyon to develop hydroelectric power. Plans centered on two sites between miles 30 and 40 in the canyon. At one point a 38-mile (61 km) tunnel was proposed to a site just outside Grand Canyon National Park to develop the site's full power generation potential, reducing the Colorado River to a trickle through the park.
