<br />:OO2.44Jements, heavy metals, salts, and nutrients will be similarly reduced ,,:hish havioge a <br /> <br />corresponding improvement in surface and ground water quality. Groundwater and <br /> <br />Arkansas River Selenium levels will be reduced to within State and EPA standards. <br /> <br />Water quality downstream will also improve. <br /> <br />IWM and endurin<] Nactices will reduce the irrigation induced erosion in the watershed <br /> <br />by 45,000 tf)ns/v,,~r with this alternative. These oracticesi& will also reduce the amount <br /> <br />of sediment aV";'2b'e for d'2livery to the Arkansas River. The sediment associated trace <br /> <br />elements, heavy m'2!8is, salts. and nutrients reaching the river will also be reduced. <br /> <br />This will also help prolong the remaining storage in the John Martin Reservoir. -The <br /> <br />downstream w[\ter lIsers w;'! benefit by receiving higher quality water and reduced <br /> <br />maintenance. <br /> <br />Project imnl"ment~tion w;'1 result in a reduction of 31,100 tons of salt annually being <br /> <br /> <br />delivered to t'le t. rV8nsas P;ver from the watershed. <br /> <br />The fish and wi!c!!:fe habitClt of some species within the watershed IW!)lwiU be enhanced <br /> <br />through the implementation of this alternative.
