Cows are natural reservoirs of African trypanosomiasis. In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival.
Kardzali Reservoir in Bulgaria is a reservoir in the Rhodope Mountains. Some reservoirs such as this in Argos, Peloponnese are made for recreational purposes, rather than storing fresh water. A reservoir ( / ˈ r ɛ z ər v w ɑːr / ; from French réservoir [ʁezɛʁvwaʁ] ) is an enlarged lake behind a dam , usually built to store fresh water ...
The list below largely ignores many natural lakes that have been augmented with the addition of a relatively minor dam. For example, a small dam, two hydroelectric plants, and locks on the outlet of Lake Superior make it possible to artificially control the lake level.
Below are the reservoirs (artificial lakes) in the world with a surface area exceeding 500 km 2 (190 sq mi). Reservoirs can be formed conventionally, by damming the outlet of a canyon or valley to form a lake; the largest of this type is Ghana's Lake Volta, with a water surface of 8,500 km 2 (3,300 sq mi).
A dam is a barrier that stops or restricts the flow of surface water or underground streams, or water reservoir resulting from placing such a structure. Delta: the location where a river flows into an ocean, sea, estuary, lake, or reservoir. Distributary or distributary channel: a stream that branches off and flows away from the main stream ...
Lake Powell, impounded by Glen Canyon Dam, is the second-largest reservoir in the U.S.. This is a list of largest reservoirs in the United States, including all artificial lakes with a capacity greater than or equal to 1,000,000 acre-feet (1.2 km 3).
This includes those formed by raising the level of natural lakes, such as at Lake Tahoe. Most large reservoirs in California are owned by the federal Bureau of Reclamation and to a lesser extent the Army Corps of Engineers , many serving the Central Valley Project or State Water Project .
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. Such reservoirs form when kerogen (ancient plant matter) is created in surrounding rock by the presence of high heat and pressure in the Earth's crust .
