Incident Description |
Partial Failure: RE visited site to observe the reported refilling of the lake (previously dam was not holding water based on all accounts and historical google earth imaging). RE noted that the dam was in extremely poor condition and the water level has receded very little since the owner engineer visited on 3/18/22. Significant sloughing into the crest near where the outlet works would have been, sloughing on downstream toe at outfall. Approximately 20' was outfill pipe was exposed and disconnected. Significant flow was exiting and around the outfall, muddy. Evidence that the emergency spillway had been activiated recently with significant erosion on the downstream embankment in the area of the emergency spillway. Dam is covered with mature trees. Widespread evidence of beaver activity. |
