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). There has been two definitions of the acre-foot (differing by about 0.0006%), using ...

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 water has continued to stream into the reservoir, and by Jan. 17 it hit a high of 334,235 acre-feet, according to Monterey County. One acre-foot of water is equal to 325,851 gallons.
All this because of the lack in ability to do this simple calculation. I will illustrate here: 1 acre (1 foot thick) x # of gallons in a cubic foot. This is, simply 43560 (Cubic feet) x 7.48 gallons / cubic foot = 325,828.8 gallons - rounded to 325,829 gallons per acre foot (do it on a calculator!).

Lake Mead receives the majority of its water from snow melt in the Colorado, Wyoming, and Utah Rocky Mountains. Inflows to the lake are largely moderated by the upstream Glen Canyon Dam, which is required to release around 8.23 million acre-feet (10,150,000 Ml) of water each year to Lake Mead under the Colorado River Compact. Releases from ...
