National Dam Safety Program. Elm Creek Dam (Dam Number 16), (Inventory Number N.Y. 593), Conewango Creek Watershed, Allegheny River Basin, Cattaraugus County, New York. Phase I Inspection Report,
Abstract
Examination of available documents and visual inspection of the Conewango Creek Watershed Elm Creek Dam (Dam No. 16) and appurtenant structures did not reveal conditions which constitute a hazard to human life or property. However, the dam has some deficiencies which require further investigation and remedial action. Sloughing of the south slope of the emergency spillway and the north upstream abutment contact was observed. In addition, significant erosion was observed on the upstream slope of the embankment. It is recommended that these conditions be evaluated further by a qualified registered professional engineer. Using the Corps of Engineers screening criteria for review of spillway adequacy, it has been determined that the dam would not be overtopped under full PMF conditions. The PMF routed through the reservoir required only 55 percent of the spillway outflow capacity. The spillway capacity is, therefore, judged to be adequate. The investigation recommended should be completed within 12 months of notification to owner, and remedial actions resulting from these investigations completed in the subsequent 12 months.
