how much liquid per acre
1.0 acre foot = 325,851 gallons 0.7 acre foot = 228,095 gallons. On a daily basis, 0.7 acre foot works out to 625 gallons/day. According to Prof. Leipnik, the average suburban family with a lawn uses 0.3 acre foot/year or 267 gallons/day. So 0.7 acre foot is over twice the usage of the average suburban family. This is obviously a lot of water.
