• i wells on the western part of the property, west of Riverdale Road will not be affected by the lowered water levels created by the new lakes. The maximu.~~ spread of drawdown resulting from the presence of the lake will be approximately 2,200 feet. These wells are located approximately 2,000 feet from the lake. In addition, seepage from the bottom of the Erantner and Lower Clear Creek ditches will ensure that the lateral expansion of drawdowns will not extend beyond tiie ditches. The South Platte River, south and east of the property, forms a hydrolog~ boundary and will restrict the drawdowns from the lakes to the mitring property. 'ihe domestic, stock and irrigation wells south and east of the river will not experience any lowering of water levels due to the creation of the lakes. Water Quality There is ..o impact from water quality, therefore, no mitigation is reyui-ad. Drainage The existing lwees along the south boundary of the site an3 along the west bank oL the South Plattc River will be maintained at their F-esent levels. To change them either higher or lower woula change the flood plain and flood flow 7 characteristics which may increase the damage p ~ ' for other areas, The lake banks should be kept 00 to 300 .2~-~ o ~t feet from the levees. This will help keep any erosio extending off the site and help maintain the existing flood flow patterns. Lake banks, especially the southern bai~cs should be kept as flat as possible and planted with suitable vegetation to help control erosion during floods. Peninsulas extending into the south lake should Le constructed at a ~r~ximum height of three feet above the final lake level. Tree planting should `+e in a manner to allow easy passage of flood flows. North-South allign~nents along the east and west shores would be ideal. No new structures for permanent occupation will be allowed. Other structures and stockpiles of mate-ials will be allign~d with their longitudinal axes in the direction of flow. -15-
