However, increased <br />snowfall raises costs for snow removal <br />and IrT8lllnche oontrol.increl'lses the <br />snow damage to orchards. reduce' <br />grazing potential for livestock and <br />wildlife in high pastures. and raises <br />cosb for mining and tirtlber operations. <br />Because of these and other insUlutional <br />faclors, major weather modification Is <br />not likely in the nearfulure. <br />5. More Efficient Water Use. The <br />demand for the ell;port of Regional water <br />outside the Upper Colorado River Basin <br />could be decreased thorugh improved <br />municipal water use effiCiency. Exports <br />for municipal use (15 percent of <br /> <br />projected depletions by convcntional <br />UlleS) ere of greater interest for the year <br />2000 than in-hasln municipal and <br />industrial use (2 percent of projec;:ted <br />depletions). <br />Techniques to reduC1'! per capila use of <br />municipal water indude voluntary -.....ater <br />conservation. education programs, <br />regulations. metl!ring. differential <br />pricing. and wastewater recycling. <br />Acrording 10 receDt studics, reductions <br />of 30 to 40 percent may be possible <br />without recycling.
