A reservoir is, most commonly, an enlarged natural or artificial lake, pond or impoundment created using a dam or lock to store water. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or ...
an artificially-created body of water, by damming a source. Often used for flood control, as a drinking water supply (reservoir), recreation, ornamentation (artificial pond), or other purpose or combination of purposes. The process of creating an "impoundment" of water is itself called "impoundment". Ice cap
The new body of water was initially called a "reservoir," but in the 1960s it was renamed the Great Sacandaga Lake in an effort to promote tourism to the area. The reservoir is managed by the Hudson River–Black River Regulating District. Today, the local businesses benefit not only from the flood protection provided by the lake, but also from ...
Lake Mathews is a large reservoir in Riverside County, California, located in the Cajalco Canyon in the foothills of the Temescal Mountains. [1] [2] It is the western terminus for the Colorado River Aqueduct that provides much of the water used by the cities and water districts of the Metropolitan Water District of Southern California (MWD).
The dam's spillway is located in the center of its body and is 200 feet (61 m) wide, containing three main 40-foot-wide (12 m) and 30-foot-high (9 m) radial gates. Two smaller 8.5-foot (3 m) wide and tall gates on the outer edges of the spillway section maintain normal discharges. The normal elevation for the reservoir is 250 feet (76 m). [4]
Falls Lake is a 12,410 acre (50 km 2) reservoir located in Durham, Wake, and Granville counties in North Carolina, United States.It extends 28 miles (45 km) up the Neuse River to its source at the confluence of the Eno, Little, and Flat rivers, and has a shoreline of 175 miles (280 km).
The residence time of a reservoir within the hydrologic cycle is the average time a water molecule will spend in that reservoir (see table). It is a measure of the average age of the water in that reservoir. Groundwater can spend over 10,000 years beneath Earth's surface before leaving. [17] Particularly old groundwater is called fossil water ...
Most modern reservoirs have a specially designed draw-off tower that can discharge water from the reservoir at different levels, both to access water as the water level falls, and to allow water of a specific quality to be discharged into the downstream river as "compensation water": the operators of many upland or in-river reservoirs have ...
