Honk Falls Dam Design
Natural Solutions to Manmade Problems
Matrix provided environmental and engineering services associated with the acquisition by the New York City Department of Environmental Protection (NYCDEP) of up to ten properties for a dam rehabilitation project.
Honk Falls Dam was located on Rondout Creek, a tributary of the Hudson River about 3 miles north of Ellenville, New York. The dam was erected in the late 1890s, for hydroelectric power, and created 40-acre Honk Lake. The Dam had been classified as a Class C High Hazard structure with risk to life and property in the event of a failure (dam blowout), according to two Army Corps of Engineers studies in 1981 and 1998. The project involved decommissioning and removing the dam. Matrix’s role for this project included assisting with the environmental review, permitting and designing of approximately 2,000 LF of new stream in the former lake bottom, remedying climate change flood control issues and helping create a natural solution to the problem.
