An acre-foot is the amount of water it would take to cover an acre of land with water 1 foot (0.30 m) deep. One acre-foot of water is the same as 43,560 cubic feet (1,233 m3) of water. It is about the same amount of water as a 8-lane, 25 m long competition swimming pool.
The typical American family uses about 1 acre-foot of water in a year or about 892.72 US gallons (3,379.3 l; 743.34 imp gal) per day. In some places in the deserts of the Southwestern United States, water conservation is a rule. In these ares, a normal family only uses 0.25 acre-feet of water per year.
Large amounts of water can also be in thousands of acre-feet or TAF.
