Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
Tulare Lake was the largest of several lakes in its lower basin. Most of the Kern River's flow first went into Kern Lake and Buena Vista Lake via the Kern River and Kern River Slough southwest and south of the site of Bakersfield. If they overflowed, it was through the Kern River channel northwest through tule marshland and Goose Lake, into ...
Lake Tahoe is the second deepest lake in the U.S. In terms of area covered, the largest lake in California is the Salton Sea, a lake formed in 1905 which is now saline.It occupies 376 square miles (970 km 2) in the southeast corner of the state, but because it is shallow it only holds about 7.5 million acre⋅ft (2.4 trillion US gal; 9.3 trillion L) of water.

The overfishing list reflects species that have an unsustainably high harvest rate. NOAA also keeps a list of overfished stocks. Those are species that have a total population size that is too low.
In 1924, the Potter Valley Irrigation District (PVID) was formed to provide irrigation water to the farmers along the East Branch Russian River. The district currently serves 390 farmers with rights to 22,670 acre-feet (27,960,000 m 3 ) of project water per year, for the irrigation of 4,905 acres (1,985 ha) within a district boundary of 6,900 ...
The lake existed in the valleys of the Sacramento River and the San Joaquin River, [2] at least as far north as the Sutter Buttes. [3] If so, it might have had a size comparable to Lake Michigan. [4] An alternate view presumes that the lake covered only the southern parts of the Central Valley. [5] The total surface covered by the lake amounts ...
Mono Lake's ecosystem for migrating birds was threatened by dropping water levels. Between 1979 and 1994, David Gaines and the Mono Lake Committee engaged in litigation with Los Angeles. The litigation forced Los Angeles to stop diverting water from around Mono Lake, which has started to rise back to a level that can support its ecosystem.
The river ended in the Uinta Basin [6] [b] and Lake Uinta in present-day Utah [7] roughly where the Green River exits the basin, [8] forming a river delta that today comprises the voluminous Colton Formation [3] and with its sediment covering an area of over 3,000 square kilometres (1,200 sq mi).
