As the name suggests, an acre-foot is defined as the volume of one acre of surface area to a depth of one foot.. Since an acre is defined as a chain by a furlong (i.e. 66 ft × 660 ft or 20.12 m × 201.17 m), an acre-foot is 43,560 cubic feet (1,233.5 m 3).
(An acre-foot is about 326,000 gallons — enough water to supply up to three homes for a year). ... state agencies permitted more than 1.2 million acre-feet of groundwater recharge — including ...
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 ...
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.
By 2050, California is expected to lose between 4.6 and 9 million acre-feet of its annual water supply. In other words, by 2050 at the latest, Californians would lose access to a volume of water ...
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). Figures given are for maximum storage capacity (flood pool) of reservoirs, not regular storage volume (conservation pool).
The state saw 4.1 million acre-feet of managed groundwater recharge in the water year ending in September, and an 8.7 million acre-feet increase in groundwater storage, California’s Department ...
The 456 billion gallons (1.4 million acre feet) of water is lifted by up to 2,900 feet by 14 pumps using 2.5 million MWh of electricity each year [285 MW], making CAP the largest power user in Arizona. Lake Pleasant is used as a buffer. [3] [4] The canal loses approximately 16,000 acre-feet (5.2 billion gallons) of water each year to evaporation.
