New Elk Mine Pond: <br />Date: 6/20/2016 <br />EMERGENCY SPILLWAY <br />1). Does it appear that the emergency spillway has discharged lw ster since the last inspection? . No <br />2). Is erosion occurring at any section of the emergency spill Yes No <br />Describe extent: <br />SEDIMENT STORAGE CAPACITY <br />1). Has the design storage capacity of the reservoir been surpassed? No _ <br />Elevation @top of: , M S 'f <br />Elevation of Water Surface. <br />Elevation to top of Sediment: a <br />OTHER OBSERVATIONS <br />Sediment and water surface elivations were determined by a differential level <br />survey of water/sediment compared to the top elevation of the primary discharge <br />riser. An arithmatic average of several sediment elevation data points was calculated. <br />Only a single reading was required for determining water elevation when water <br />was present. Water depth to sediment was determined from depth readings using a kayak <br />and range pole, then average depth and sediment elevation calculated and plotted <br />on the pond's stage storage curve. <br />MS A Qualified Impoun ment spector Professional Engineer Directing inspection, <br />%a� l Date <br />Date �y <br />Page 2 of 2 `�qg� <br />
