National Dam Safety Program. Lake Muskoday Dam (Inventory Number N.Y. 341) Delaware River Basin, Sullivan County, New York. Phase I Inspection Report,
Abstract
Lake Muskoday Dam consists of a stone masonry and stone fill structure with an upstream concrete wall and a concrete overflow spillway in the central portion. The dam structure is approximately 17 feet high; it has an irregular upstream earthen slope below the projecting concrete wall and irregular downstream rockfill that has a slope in the range from 2 to 3 horizontal to 1 vertical. The visual inspection revealed several deficiencies on this structure: (1) Water flow estimated at greater than 40 GPM was exiting from the rockfill on either side of the overflow spillway; (2) At and slightly above the waterline, there was local erosion of the upstream embankment; (3) The partially-paved roadway along the dam crest has local, shallow potholes; (4) At both ends of the dam, the downstream rockfill slope has weeds, brush, some debris and at least one tree among the rock fragments, and (5) The swale between the downstream slope and the right abutment has undergone some erosion.
