Inspections for Stockponds T-1, T-2, T-3, T-22 and T-24 <br />are included. Most of the stockponds have been cleaned out and <br />the sediment removed from them. stockpond T-7 is no longer a <br />stockpond and the embankment has been converted into a portion <br />of the diversion ditch within 006 Gulch which directs water into <br />the B pit pre-settling basin. T-22 will need to be reconstructed <br />entirely since portions of the dam and spillway have washed out <br />completely. Further maintenance to these areas will be done this <br />upcoming spring when the weather and ground conditions allow. <br />Should you have any questions, please do not hesitate to call. <br />zeass <br />G.
