• are infrared and show the late summer and fall season differences in vegetative growth <br />between upland and valley floor areas. Goodspring Creek shows some evidence of being an <br />alluvial valley floor. <br />Effects on Essential Hydroloeic Functions <br />Based on information accumulated, the effects of mining on any alluvial valley floor which <br />exist in the general area would be minimal. Because of the undefined perched existences and <br />limited amounts of groundwater in the area to be mined, the planned mining will not directly <br />impact any alluvial valley Floor. Any water recharge of the nearby drainages and <br />unconsolidated material from the mine would be negligible in comparison with the overall <br />natural flows of the streams recharged in areas above the operation. <br />The flood plains of Goodspring Creek, Wilson Creek and lower Taylor Creek may meet the <br />geomorphic criteria and flood ircigation requirements of an alluvial valley floor. Runoff from <br />the mining operations drains into these floodplains. Therefore, Colowyo was taken <br />appropriate measures to protect the essential hydrologic functions by designating stream <br />buffer zones and by installing sedimentation ponds on the drainages from disturbed areas <br />feeding into Goodspring Creek, Wilson Creek, and Taylor Creek (see Hydrology - Nor[h <br />Map (Map 11) and Hydrology -South Map (Map 12}). The overall role of the floodplains in <br />collecting, storing, regulating and yielding water for agricultural activities has been <br />unchanged and should continue to be unaffected by the mining operations. <br />The- possible alluvial valley floors in the vicinity of the mine will incur no adverse impact <br />due to mining by Colowyo. Surface water pollution will be prevented by sedimentation <br />ponds, sediment control measures, proper mining and reclamation techniques, and frequent <br />monitoring of discharge water quantity and quality. The hydrologic consequences of mining <br />will not result in disruption of the essential hydrologic functions due to the beneficial effects <br />of water treatment and flood control provided by the sedimentation ponds and natural <br />dilution of potential mine discharge to the existing streams. <br /> <br />2.06-13 <br />
