Attached are some pics to help with the comments. Overall the site at the pond is found in compliance with the EC plans. The turbidity curtain was floating and appeared to be functioning as intended. There is some turbidity at the existing pipe outlet into the pond. The skimmer discharge was very clean. The existing ditch line between skimmer and the existing pond pipe is not an improved ditch and has a lot of brush in it. The turbidity appears to be from the pipe discharge dropping into the pond. The area feeding the skimmer has been revegetated and no active work is going on at this time. Also included are pictures of the upper pond with no overland flow from the project. The water condition appears to be visually similar to the larger pond receiving the skimmer discharge. In summary, we are sending stormwater flow into the pond per our permits. Efforts have been made to limit turbidity impacts and prevent offsite sedimentation into the pond. No doubt with the rains, there are impacts to turbidity levels but I think at this time, every reasonable effort has been made to limit those impacts.
