Water Calc assists irrigators in the High Plains Underground Water Conservation District calculate their water use based on the alternative method established by the district. By entering beginning and ending fuel meter readings, the fuel type and county, a producer can calculate the acre inches applied for annual reporting purposes.

Additionally, by entering the acres covered, hours of operation and fuel cost per meter unit, the irrigator can also calculate the gallons per minute being pumped, the cost per acre and the acre-inches applied per acre.
