Lacking an <br /> <br />up-to-date inventory of incidental use lands, these percentage <br /> <br />adjustments may have to be retained for use in this study and <br /> <br />applied against the annual estimates of irrigation consumptive <br /> <br />uses. <br /> <br />(4) Stockpond and Livestock <br /> <br />Recent inventories or estimates of stockpond numbers and sizes <br /> <br />will be obtained from, BLM, SCS, Forest Service, and BIA. <br /> <br />Annual equations of net water surface evaporation will be <br /> <br />applied against the estimated average annual total surface area <br /> <br />of stockponds within a reporting area to yield the values of <br /> <br />stockpond evaporation. Net animal unit consumptive use will be <br /> <br />applied against the number of animals reported in the State <br /> <br />agricultural reports. <br /> <br />Municipal and Industrial <br /> <br />(1) Mineral <br /> <br />Water use rates per ton of production of various minerals <br /> <br />will be obtained from the Bureau of Mines along with reports of <br /> <br />annual production. <br /> <br />11 <br />
