I I I I I I I I I I I I I I I I I I I use data was analyzed, extending from October, 1988 through July, 1991 (Table IV-D). The average summer monthly use was 174,800 gpd or 141 gpcd; average winter use was 123,500 gpd or 100 gpcd. The Table also indicates that total water usage in 1991 was 180.8 acre feet and 152.3 acre feet in 1990. The 1989 usage is probably reflective of maximum year requirements because of the hot, dry weather in that period. If the Gurley Reservoir system is used, the 1989 numbers would be helpful in determining the amount of storage and direct flow water required. The higher summer use is obviously due to irrigation water Use. Winter* Monthly Daily Per Capita Summer** Monthly Daily Per Capita Annual Total Gal.

The average monthly water use is highest in May and June, and then drops off in July. July is normally the hottest month of the year and would typically have the greatest irrigation requirements; however, weather records indicate that normal average precipitation in July is almost double that in June. August precipitation is even higher (Table IV-E). IV-5
