Both are in the municipalities of Bischoffen and Hohenahr in the county of Lahn-Dill-Kreis and about 15 km northwest of the town of Gießen in Hesse. On the lakeshores lie the villages of Ahrdt and Mudersbach, both part of the parish of Hohenahr. Since 1991 the dam has impounded the River Aar, a left-hand tributary of the Dill in the Gladenbach Uplands. The reservoir is also fed by the Stadterbach, Wilsbach (into the forebay), Weidbach and Meerbach (into the main reservoir). UseThe dam is primarily used for flood protection for the Aar and Dill. In Winter the reservoir is filled to a capacity of 1.33 million m³; in summer this rises to 1.84 million m³. Other uses are: raising low water levels, electricity generation, fishing and recreation. As a result, the dam and reservoir also contribute economically to the region. The reservoir was opened in 1992 as a bathing lake. Its operator is the county council of Lahn-Dill-Kreis and the Dillgebeit Water Association. See also
