Should it appear that <br />some adverse affects may result from the mining operation, <br />remedial measures will be taken by Western Paving to <br />correct the problem, so that no ground water users will <br />be affected. <br />DI~PCH PROTECTION <br />To determine seepage losses from Idaho Creek, due to the <br />realignment or mining, wiers exist at the point where it <br />enters the property and exits the property. These will <br />be measured to detect any adverse affects. <br />In addition, Parshall measuring flumes, will be installed <br />to measure the inlet of the Carr 6 Tyler, N.K. Smith ~ <br />Tyler, Smith b Emmons, Godding and CBT Waters. Parshall <br />flumes will also measure the outlet of the Smith ~ Emmons <br />the only down stream water used by others. <br />By this method, Western Paving can guarantee that the same <br />quantity of water entering the project area will exit, so <br />that no ditch user will be affected. <br />AQUACULTURE <br />Previous reclamation philosophies at other mining sites, <br />involved mostly visual esthetics; that of contouring and <br />planting trees and grass. <br />The :reclamation plan to be put into effect here, is to <br />improve the quality of the water in lakes for fish breeding <br />and habitat. Lakes and ponds without a flow of water <br />through them, tend to stagnate thus limiting their value <br />for supporting a variety of aquatic species. <br />;::~: <br /> <br />
