Acre feet
An acre-foot is a unit of volume commonly used in the United States in reference to large-scale water resources, such as reservoir]]s, aqueducts, canals, sewer flow capacity, and river flows.

DefinitionEdit

It is defined by the volume of one acre of surface area to a depth of one Foot. Since the area of one acre is defined as 66 by 660 feet chain by a furlong then the volume of an acre-foot is exactly 43,560 cubic feet. Alternatively, this is approximately 325,851.4 U.S. gallons or 1,233.5 kL (or m³).

DiscussionEdit

As a rule of thumb in U.S. water management, one acre-foot is taken to be the planned water usage of a suburban family household, annually.[1] In the desert SouthWest, where water conservation is followed, a typical family uses only about 0.25 acre-feet of water per year.[2]

The acre-foot (or more specifically the time rate unit of acre-foot per year) has been used historically in the U.S. in many water-management agreements, for example the Colorado River Compact, which divides 15 million acre-feet per year (586 m³/s) among seven western U.S. states.
