Apri19, 2014 C- 1981 - 010 /Trapper Mine JLE <br />dams have been repaired. Many of the check dams in this channel have been constructed with very large boulders. <br />These check dams appear to be more prone to failure as water tends to cut around and under the rock. Many of <br />these large boulders have rolled down inside the channel where the water cuts around them. In October of 2012 it <br />was observed that in many places of this channel, the channel had eroded to a deeply incised gully with vertical <br />side slopes. Many of these slopes have been graded out but are still fairly steep. A portion of the upper reaches of <br />the channel are becoming more incised and eroded and several of the check dams have failed. I collected a line <br />feature with my YUMA GPS unit to highlight the area were future repairs are needed. See the enclosed map. <br />Three large dozer basins have been constructed at the head of this reconstructed drainage adjacent to parcel A -B- <br />09. These basins are swollen with sediment and will need to be cleaned out. Trapper may want to increase the <br />frequency of cleaning these particular dozer basins to slow /limit the flow down the gulch. <br />West Flume reconstructed drainage was walked. This is a small channel corridor through Parcel A-13-0 1. The <br />parcel has been Phase III bond released. In general, this is a wide channel. The upper (southern) reaches of the <br />channel are stable with a small center channel that has not incised significantly. The lower portion of the channel <br />appears to be steeper. The center channel in the lower portions of the drainage has become incised and is about 5 <br />feet deep in places with vertical side slopes. At observation point WF1, a check dam failure was noted. At <br />observations point WF2, the deep center cut channel was noted. The lower reaches of this channel will need to be <br />repaired. <br />No Name 45R pond was discharging. The pond embankment was stable and the primary and emergency spillway <br />was clear and functional. <br />The Middle Pyeatt Ponds were dry. The ponds were viewed from the access road south of the ponds. The back <br />side of the embankments appeared stable and the primary and emergency spillways were clear and functional. <br />East Pyeatt Pond 41 was discharging. The primary and emergency spillway was stable and functioning. The <br />embankment was stable and vegetated. <br />East Pyeatt Pond 42 was discharging. The embankment was stable and vegetated. The primary and emergency <br />spillway was clear and functional. <br />East Pyeatt Pond 43 was discharging. The primary and emergency spillways were clear and functional. The <br />embankment was stable and vegetated. <br />Oak Ponds 41 and 42 were discharging. The embankments were stable and vegetated. The primary and <br />emergency spillways were clear and functional. <br />Horse Gulch Pond was discharging. The embankment was stable and vegetated. The primary and emergency <br />spillways were clear and functional. <br />West Horse Pond was holding water but was not discharging. The embankment was stable and the primaiv and <br />Number of Partial Inspection this Fiscal Year: 7 <br />Number of Complete Inspections this Fiscal Year: 3 <br />Page 5 of 22 <br />
