The CU model has the flexibility of changing the various coefficients used to estimate <br />consumptive use for agricultural and other uses. There are options for changing livestock consumptive <br />use coefficients, reservoir evaporation characteristics, etc. Default values are used unless a user chooses <br />to modify these parameters. <br />Counties and Hydrological Units (HU) were broken up to include each combination of the intersection of <br />a county and an HU (County-HU units). Therefore, the consumptive use can be estimated for counties <br />and HUs. The following categories are described as other uses in the U.S. Bureau of Reclamation?s <br />Colorado River System Consumptive Uses and Losses Report, 1981-1985 . <br />4 <br />A275 01.09.95 1.14-9 Lange <br />
