<br />Description And Effects of Alternative Plans <br />002438 <br /> <br />Three approaches to treatment were considered and various alternatives were <br /> <br />developed incorporating these various approaches. The approaches included t:l.Q <br /> <br />ActionElo nothing, QGnly GGhanqinq Mmanaqement P/:lractices, and a Goombination of <br /> <br />Mmanaoeme'lt Cchanaes and Eendurinq Mmeasures. Other approaches considered <br /> <br />did not meet sponsors objectives. <br /> <br />The following alternatives were considered during this process: <br /> <br />Alternative 1: Future without Project <br /> <br />Studies of past 8chievements of land users in the watershed indicate that funds from <br /> <br />the on-going programs are adequate to treat less than two percent annually of those <br /> <br />areas with erosion, and water quality and quantity problems. An analysis of available <br /> <br />ongoing moneys indicate that $40,000-50,000 is available in the watershed on an <br /> <br />average annual bilSis from other programs. At this rate of funding, it would take at least <br /> <br />75-100 years to complete the work proposed without PL-566 cost-share program <br /> <br />funding. <br /> <br />Effects - W"hout Irrigation systern improvement, deep percolation and runoff will <br /> <br />continue at i's current unacceptable level. Irrigation water application effectiveness will <br /> <br />continue to be a pr~blem, Irrigation induced erosion will continue to damage the upper <br /> <br />portions of the fields resulting in topsoil and yield losses.
