Mohelno reservoir is the lower balancing reservoir of the Dalešice waterworks on the Jihlava River, about 30 km southeast of Třebíč, in operation since 1977. Its concrete gravity dam is 185 m long at the crest, 7.75 m wide, 32 m wide at the foundation and 38.65 m high above the riverbed, built with 89,400 m³ of concrete.
