I <br /> <br /> f9ined Land Reclamation Board. <br />Impact of Mining and Reclamation <br />Presently, Flatiron Paving Company is mining by dry operation <br />which requires dewatering prior to stripping and crushing. The <br />dewatering trench encompasses the operation and completely de- <br />waters the area inside the trench. The water table is lowered <br />throughout the property and outside the boundary of the mining <br />' operation. Previous mining operations will result in 18 acres <br />of open surface water on the property following reclamation. <br />I Water use under future conditions will be 45 acre-feet annually. <br />The evaporation of water from the lakes will reduce stream <br />I flows. Because of the proximity of the operation to the river, <br />the reduction in stream flows will occur at approximately the <br />same time as evaporation will occur. <br />Mitigation of Mining and Reclamation Impacts <br />The 18-acre lake that exists on the mining site and will be <br />present after reclamation was created by mining operations <br />prior to 1976. Because the open water surface was created <br />prior to the enactment of the present Mined Land Reclamation <br />Board water requirements, no mitigation measures are proposed <br />I to reduce the evaporation losses from the lake. To ensure that <br />ground water levels are kept far enough beneath the land surface <br />to reduce the potential of sub-irrigation, an outlet drain from <br />the lake to the river will be constructed at the eastern part of <br />C-6 <br />
