convert pond surface area in square feet to surface area in acres. For example: Pond length 700 ft × pond width 300 ft = 210,000 ft2 Pond surface area of 210,000 ft2 ÷ 43,560 ft2 per acre = 4.82 acres The average depth of the pond must be calculated to determine its water volume in acre-feet (1 acre-foot is 1 acre of water, 1 foot deep).
