Section 15 pond. <br />West Pit: <br /> <br />Three ditches within the West Pit were inspected along with the associated stock ponds. This included the Taylor <br />Ditch, East Taylor Ditch and Buckskin Ditch. The Buckskin ditch has only a portion constructed at the moment <br />and is located in the eastern portion of the West Pit. A new portion of the Taylor Ditch had recently been <br />constructed. The area was in need of final touches to meet approved specifications as approved in the Colowyo <br />PAP once ground conditions allowed. The Taylor Ditch is lined with rip rap for its entirety and no issues were <br />observed. The East Taylor Ditch is mostly lined with rip rap with a portion that is a vegetated channel just above <br />stock pond ETD1. The lower portion of the East Taylor Ditch recently received maintenance and remains stable. <br />No issues were observed with all ditches or associated stock ponds within the West Pit. <br /> <br />The West Pit Pond and East Taylor Pond are associated with the West Pit and were inspected. The West Pit Pond <br />was dry and the East Taylor Pond held water and was discharging at the time of the inspection. Most of the water <br />received from the East Taylor Pond comes from a spoil spring located just above the pond. The spring has been <br />intercepted by a french drain which diverts the water to a flume where flow can be measured. Water elevations <br />within the pond were high. Aquatic vegetative overgrowth noted in the Division’s September inspection has been <br />removed from the primary spillway allowing for proper discharge to occur and water levels in the pond to lower.
