The Natural Dam Project consists of: a 230-foot-long, 3-foot-high concrete dam with a 155-foot-long spillway equipped with a 2.2-foot-high inflatable rubber dam and a 180-foot-long auxiliary dam/spillway; a 570-acre impoundment with a normal water surface elevation of 396.0 National Geodetic Vertical Datum (NGVD) ; a 152-foot-long headpond connected to a wooden power flume; a powerhouse containing three turbines directly connected to two 300-kW and one 420-kW generating units for a total installed capacity of 1,020 kW; a tailrace; and an 80-foot-long, 23-kilovolt transmission line.
The project creates a 570-foot-long bypassed reach. There are no recreational facilities at the project.
