Abstract
Hillburn Reservoir Dam, located on an unnamed tributary of the Ramapo River, is 0.8 mile west of Hillburn, New York. Hillburn Reservoir was originally used as a water supply for the Village of Hillburn New York, but was abandoned two years ago because the flow quantity and quality were unreliable. The visual inspection revealed several deficiencies in this dam. The following items were noted: Three small piping holes, flowing at 2-3 gpm, were observed at the toe of the dam; Two seeps are located on the downstream face of the dam beneath the spillway. Also, there are several smaller seeps located beneath the spillway; The mortar in the masonry joints is generally deteriorated with many cracks and gaps, especially from the spillway to the right abutment; The valves for the blow-off pipes have not been operated for 7 to 9 years; The downstream channel below the spillway is full of large boulders and debris; There are three trees growing in the masonry face of the dam, and many trees growing at the toe of the dam; The masonary joints in the foundation, and the entire valve house is a deteriorated condition; The concrete wing wall at the right abutment has collapsed, and There is some spalling present on the upstream face of the concrete cap.
