National Dam Safety Program. Little Choconut Watershed Site 2A Dam (Inventory Number NY 720), Susquehanna River Basin, Broome County, New York. Phase I Inspection Report
Little Choconut Watershed Site 2A Dam is one of eight floodwater retarding dams in the Little Choconut, Finch Hollow, and Trout Brook watersheds designed to reduce floodwater damages. The dam embankment is approximately 530 feet long, 33 feet high and has an upstream slope of 3 horizontal to 1 vertical and a downstream slope of 2.5 to 1. The principal spillway is a drop inlet structure consisting of a single stage reinforced concrete riser, a 24 inch diameter prestressed concrete cylinder pipe and a channel excavated into bedrock at the outlet of the conduit. The emergency spillway is a curved 80 foot wide channel with 3 to 1 side slopes cut into earth at the left abutment. Hydrologic/hydraulic analyses performed in accordance with the Corps of Engineers' Recommended Guidelines for Safety Inspection of Dams indicate that the principal spillway and the emergency spillway would pass 100 percent of the outflow from the Probable Maximum Flood (PMF) without overtopping the dam. Therefore, the combined spillway capacity is adjudged to be adequate.
