Namaske Lake




Namaske Lake was named in 2008, and is the body of water formerly referred to as Piscataquog River. The lake is public, and is owned by the State of NH. There are 145 Homes around the Lakes shoreline, both Goffstown and Manchester, NH.  There are an additional 60 back lots with lake rights.

The impoundment that comprises Namaske Lake is formed by the Kellys Falls Dam, which is owned by the State of NH, and leased to Green Mountain Power Corporation, who operates the Dam to generate electricity.

In addition to a number of private boat ramps, there is a public boat ramp on Electric Street in Manchester, near the Dam.

The lake covers 192.5 Acres, with a maximum depth of 25.41 feet, and a mean depth of 5.28 ft. Namaske Lake is relatively shallow with silty and organic substrates, essentially creating prime variable milfoil habitat across nearly the whole impoundment where depth is not a limiting factor.
