CRDSS <br />TASK MEMORANDUM 2.09-11 <br />Consumptive Use Model <br />Non-Irrigation (Other Uses) Consumptive Uses and Losses <br />in the White River Basin <br />1.0 ISSUE <br />This task memorandum formalizes the computation of non-irrigation categories such as livestock, <br />stockpond, municipal, thermal electric, mineral res ource, export, fish and wildlife, and recreation <br />categories for the CRDSS consumptive use (CU) in the White River Basin for calendar years 1985 <br />to 1990. These categories are the same as those included in the USBR Colorado River System <br />Consumptive Uses and Losses Report (USBR, 1991) produced every five years. <br />2.0 DISCUSSION/ANALYSIS <br />The estimation of non-irrigation consumptive uses and losses from the entire White River basin can <br />be performed either by county (Garfield, Moffat and Rio Blanco) or by hydrologic unit HUC sub- <br />basin (14050005, 14050006 and 14050007). The US Bureau of Reclamation (USBR) used the <br />intersection of counties and Hydrologic Units as the subdivisions for the crop consumptive use in its <br />Colorado River System Consump tive Uses and Losses Report, 1981-1985 (USBR, 1991), but for <br />some of the other uses (e.g. thermoelectric, mine ral) they used either county or HUC depending on <br />the available data. <br />To preserve consistency with these published repor ts and the units of the source data, other use data <br />are reported in Hydrologic Units, County (calculated) , or the intersection of County and Hydrologic <br />Unit. County data are determined based on GIS data showing the percentage of each County <br />contained in the White River Basin. <br />2.1 Livestock <br />As in (USBR, 1991) three types of live stock are included: cattle, sh eep and hogs. Table 1 shows the <br />average daily water consumption of each livestock type. <br />For the years 1985 to the present, the County Agri cultural Statistics (CAS) no longer reports the <br />number of livestock by county, instead records th is information for the entire state of Colorado. <br />Therefore, the US Census of agriculture was used. <br />This census is conducted every five years. The census data for 1982, 1987, and 1992 were used. <br />These data can be obtained from the US Census world wide web page at <br />http://sasquatch.kerr.orst.edu/ag-stateis.html. <br />Using linear interpolation, values for the years 1985-1990 were calculated. The values for each <br />county were distributed by s ub-basin based on the area (obtai ned from GIS) of each county <br />contained in the White River Basin (Ga rfield 13%, Moffat 10%, and Rio Blanco 90%). <br />Table 2 shows the number of livestock type by County, and Table 3 shows a summary of the <br />estimated consumptive uses for 1985-1990. <br />1 <br />01.21.97 02.09-11 CSU/IDS <br />
