National Dam Safety Program. Ischua Creek Watershed Dam Number 5 (Inventory Number N.Y. 565), Allegheny River Basin, Cattaraugus County, New York. Phase I Inspection Report,
Abstract
The dam is located on a tributary of Gates Creek in the Town of Lyndon, 3.5 miles southeast of Franklinville, New York. The purpose of this dam is to reduce downstream flooding by providing temporary storage for the runoff from 4,096 acres. The temporary storage is released gradually through the two-stage principal spillway system. The dam is generally in good condition. The potential problems noted during the visual inspection are listed below: Drainage gullies on the main dam and upstream of the emergency spillway; Ponded water in the emergency spillway channel and the berm on the downstream slope; Erosion of the downstream channel banks above the level of the rip rap; Sloughing of the upstream slope to the left of the intake structure; Operation of the drain gate could not be checked due to its location below the water surface, and The inaccessibility of the drain gate.
