| Relation | Central Utah Project; Western Waters Digital Library; developed water could be reduced to 0.20 020 acre foot annually per capita 180 gpcd the total water use would drop to about 0.23 023 acre foot in salt lake county and to about 0.24 024 024 acre foot in northern utah county this would extend the readily developable water supply to about 2006 or 2009 this is shown graphically in figures H a and hb H b for salt lake and northern utah counties respectively if use of both existing and new water from present sources could be limited to 0.20 020 acre foot present supplies would be sufficient until about 1987 in salt lake county and until about 1994 in northern utah county further utilization of additional water from present sources would meet water needs until about 2015 in salt lake county as shown in figure H c this would be a 26 percent reduction in use for salt lake county and a 31 percent reduction in per capita use for utah county irrigation conversion water could meet the needs in northern utah county until 2020 as indicated in figure H W d A long term reduction of the per capita use rate of existing supplies to 0.20 020 acre foot annually may only be possible by further unspecified adjustment of water rights As about 17 percent of the per capita use rate in salt lake county is comprised of a light manufactur manufaclur manufacture ing and high quality industrial use component it is also likely that these concerns would have to curtail their operations it is interest ing to note that communities in the denver colo area for instance that have attained a level of use of about 0.20 020 acre foot are both cooler and wetter during the growing season than is the salt lake city area this is indicated in the following table table H a normal precipitation and normal average temper temperature ature1 Y apr aar may june july aug sep oct season salt lake city precip precia in 2.12 212 1.49 149 log 109 1.30 130 0.70 070 0.93 093 0.68 068 1.16 116 116 8.38 838 temp F 49.2 492 492 58.3 583 583 66.2 662 662 76.7 767 767 74.5 745 745 64.8 648 648 52.4 524 524 63.2 632 632 denver precip precia in 1.93 193 2.64 264 1.93 193 1.78 178 1.29 129 1.13 113 1.13 113 11.83 1183 temp F 47.5 475 475 57.0 570 570 66.0 660 660 73.0 730 730 71.6 716 716 62.8 628 628 52.0 520 520 61.4 614 614 I 1 climatological data national oceanic and atmospheric adminis aration tration environmental data and information service 1978 the difference in net consumptive use or crop irrigation requirement for clover grass of the two areas is about 0.40 040 acre foot per acrel acre thus 25 percent more water during the growing season is req required uired aired to maintain the same landscaping in salt lake and northern utah counties this translates into a comparable use rate of about 22 .22 22 acre foot 200 gpcd for the salt lake area or a 13 percent decrease from the 25 .25 25 acre foot figure used for planning purposes I 1 crop consumptive irrigation requirements and irrigation effi clency coefficients for the united states USDA soil conservation service june 1976 H 5 |
