The barrier is a rockfill dam[1] with asphalt concrete interior sealing (bituminous core). The dam is made of granite and bunter sandstone and was constructed from May 1981 to October 1982. The initial impoundment of the river lasted from 13 December 1982 to June 1984.
Overflow protection is housed in a tower with a circular spillway in the reservoir, to which a gallery is connected. The rated capacity of the power plant is 580 kW. The reservoir supplies between 3 and 8 million m³ of drinking water annually.
The reservoir is ca. 3 km (1.9 mi) long, 450 m (1,480 ft) wide and has a maximum depth of 60 m (200 ft).
There is also a forebay with a 15 m (49 ft)-high dam made of earth and rock from the hillside (Hangschuttmaterial).
The Kleine Kinzig dam should not be confused with the Kinzig Dam near Steinau in Hesse.
