Reported or measured water-use data for the domestic self-supplied user were not available for Oklahoma; therefore estimates of water use within this classification were derived. The total self-supplied population in Oklahoma during 1980 was estimated to be 343,615, which was 11.4 percent of the total 1980 State population. The rate of water use by this group was estimated to be 56 gallons per capita per day. The estimated annual domestic self-supplied water use by county ranged from 10 to 1,180 acre-feet, with a total statewide use of 21,610 acre-feet.
