More condition and <br /> <br />trend surveys.o! the public. range are requirea to determine proper stocking <br /> <br />rates and identify needed adjustments in the use 6f the range and management <br /> <br />practice s. <br /> <br />Complete hydrologic data such as precipitation records, groundwater <br /> <br />recharge ra,tes, infiltration rates, and soil m.oisture storing capacities are <br /> <br />needed. Such data would facilitate the prope r handling of groundwate r <br /> <br />systems, land classification, and development of range improvements,. such <br /> <br />as spring and well developments. 'I'he data would also minimize the tendency <br /> <br />to overdesign water structures, at the same time insuring that structure <br /> <br />specifications are adequate for the hydrologic conditions likely to be <br /> <br />encountered. <br /> <br />2. Effects of public land disposition and use on the water problems and <br /> <br />needs. The previously described public land uses and practices all, in llome <br /> <br />. way, involve the need for more efficient water utilization. ';['he vast utiliza" <br /> <br />. <br /> <br />tion of the public lands is a~most entirely dependent on local groundwater' <br /> <br />sources and alil'the uses intensify on the public lands, the water situation <br /> <br />will.become more and more critical. Expanding range, wildlife, recreation, <br /> <br />and agricultural use~, as well as urban development, will deplete local water <br /> <br />sources on the public lands. As land uses are intensified, better management <br /> <br />of existing water sources will be required. <br /> <br />20 <br />
