The acre-foot is a non- SI unit of volume equal to about 1,233 m 3 commonly used in the United States in reference to large-scale water resources, such as reservoirs, aqueducts, canals, sewer flow capacity, irrigation water, [1] and river flows. An acre-foot equals approximately an eight-lane swimming pool, 82 ft (25 m) long, 52 ft (16 m) wide ...
About 16.5 million acre-feet (20.4 km 3) of water entering the Delta in a typical year flows through the Delta into San Francisco Bay, including 6.3 million acre-feet (7.8 km 3) in governmentally mandated environmental flows; 22.4 million acre-feet (27.6 km 3) is used for other environmental purposes, and 1.6 million acre-feet (2.0 km 3 ...
statvolt (CGS unit) statV. ≘ c ⋅ (1 μJ/A⋅m) = 299.792458V. volt (SI unit) V. The difference in electric potential across two points along a conducting wire carrying one ampere of constant current when the power dissipated between the points equals one watt. [ 32 ] = 1 V = 1 W/A = 1 kg⋅m2/ (A⋅s3) = 1 J/C.

The San Diego County Water Authority signed a contract with the plant operator to purchase a minimum 48,000 acre-feet per year of water, but it can also demand up to a maximum of 56,000 acre-feet per year. [40] [41] This is equivalent to 43 million gallons per day (mgd), or about 86% of the plant's output.
CRA pumping expanded from about 16,500 acre-feet (20,400,000 m 3) of water in 1950 to about 1,029,000 acre-feet (1.269 × 10 9 m 3) by 1960. On August 9, 1962, the Metropolitan set an all-time delivery record of 1,316,000,000 gallons of water in just a 24-hour period. [citation needed]
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).
