These state-wide projections of <br />diversions required and consumptive use are shown in Table 7-1. <br /> <br /> <br />TABLE 7~1 <br /> <br />PRESENT WATER USES AND PRELIMINARY PROJECTIONS OF WATER NEEDS IN UTAH <br /> <br /> ( In 1000 Acre~Feet) <br /> Projected <br /> Present Year 2000 <br /> Diverted Consumed Diverted Consumed <br />Marshlands, Mountain Meadows, etc. 2,499 2,377 2,329 2,100 <br />Irrigation 3,500 2,308 4,750 3,144 <br />Municipal and Industrial 479 146 1,615 477 <br />Water Surface Evaporation 544 544 579 579 <br />Total 7,022 5,375 9,273 6,300 <br /> <br />The apparent decrease in over~ll efficiency (ratio of consumption to <br />diversions) results from the increas~ in M&I use, which does not consume as <br />large a percentage of diversions as does agriculture. The amount of diver- <br />sions required does not represent a true requirement in terms of total water <br />supply, since reuse of water is often feasible. Consumption, however, does <br />prescribe a lower limit below which the supply may not fall. <br /> <br />Wasatch Front <br /> <br />General <br /> <br />The Wasatch Front has been divided into three hydrologic basins, <br />the Bear, Weber, and Jordan River systems. For this study, the headwater <br />regions have been ignored and data presented only for the heavily-populated <br />valley counties. These counties are Box Elder for the Bear River system; <br />Weber and Da~is in the Weber River System; and Salt Lake, Utah, and northern <br />Juab in the Jordan River system. The map, Figure 7-1, shows these areas <br />with the location of urban, agricultural, and marshland areas and their <br />relationship to the major rivers. <br /> <br />-20- <br /> <br />TABLE 7-1 <br />
