The 301,000 acre⋅ft (371,000,000 m 3) capacity reservoir was created by the construction of the Indian Valley Dam across the north fork of Cache Creek in 1975 (49 years ago) (). The 965 ft (294 m) long and 201 ft (61 m) high earth-fill dam was built for water storage, irrigation and flood control. [ 1 ]
The 213-foot (65 m) dam was to impound 50,000 acre-feet (0.062 km 3) in a 580-acre (230 ha) lake. Ten families would have been displaced and bout 300 acres (120 ha) of farmland would have been inundated. Cost-benefit ration was calculated at 1.7, largely on the basis of the potential project's prospects for "excellent fishing."
The side of a levee in Sacramento, California. A levee (/ ˈ l ɛ v i / or / ˈ l ɛ v eɪ /), [a] [1] dike (American English), dyke (British English; see spelling differences), embankment, floodbank, or stop bank is an elevated ridge, natural or artificial, alongside the banks of a river, often intended to protect against flooding of the area adjoining the river.
The project mainly utilizes water from the South Fork American River and its tributaries, although some water is drawn from the Rubicon River, a tributary of the Middle Fork American River. Project dams provide water storage of about 430,000 acre⋅ft (530,000 dam 3 ) and a total hydraulic head of 5,417 ft (1,651 m) from the highest reservoir ...
Olivenhain Dam is a gravity dam near Escondido, California, United States. The dam was constructed between 1998 and 2003 as part of San Diego's Emergency Storage Project with the primary purpose of water supply for municipal use. It does not sit on a river or stream but is supplied with water by a system of pumps and pipes.

Graham's 1999 study [65] of US dam failures resulting in fatalities from 1960 to 1998 concluded that the failure of dams between 6.1 and 15 m high (typical height range of smaller dams [66]) caused 86% of the deaths, and the failure of dams less than 6.1 m high caused 2% of the deaths.
Medlow Dam is a small water storage dam which utilises a thin-arch concrete wall under high stress. Its design capacity for the reservoir is 304.5 megalitres (10.75 × 10 ^ 6 cu ft), with a wall height (maximum) of 20.6 metres (68 ft). The radius of curvature for the dam wall is 18.5 metres (61 ft), the length of the wall is 38.2 metres (125 ft ...
