National Dam Safety Program. Conewango Creek Dam (Site 16A), (Inventory Number N.Y. 557), Allegheny River Basin, Conewango Creek Watershed, Cattaraugus County, New York. Phase I Inspection Report
Abstract
Examination of available documents and visual inspection of the Conewango Creek Watershed Conewango Creek Dam (Site 16A) 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. Significant erosion was observed on the upstream slope of the embankment. In addition, springs were observed on the west slope of the west emergency spillway, and a ponded water condition was observed at the upstream end of the east emergency spillway. It is recommended that each of these conditions be further evaluated 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 62 percent of the spillway outflow capacity. The spillway is therefore judged to be adequate. (Author)
