Husinec Reservoir, reservoir in Husinec, Czech Republic

Husinec Reservoir is a drinking-water reservoir on the Blanice River, held by a curved gravity masonry dam 197 m long and 27.2 m high. Its five spillway fields sit at 528.33 m above sea level, and the backed-up water reaches up to 3.5 km upstream. The dam was built from stone quarried at Kobylí hora near Prachatice.

The dam was completed in 1939 to protect nearby villages from flooding during heavy rains and spring snowmelt. A small hydroelectric plant with a single turbine was built below the dam in the early 1950s to generate power for the region.

The reservoir is a drinking-water source for Prachatice, so recreation on the water is not part of local use. The dam crown carries the road between Husinec and Prachatice, and the waterworks stands on Šibeniční vrch. The reservoir was named after the town of Husinec, whose cadastral territory forms its northern edge.

The dam is 197 m long and 27.2 m high, and a 5 m wide road between Husinec and Prachatice runs over its crest. The reservoir is a drinking-water source for Prachatice, so access to the water and banks is restricted. The dam lies between Hrádek (565 m) and Výrovčice (708 m) hills, 2 km south of Husinec.

The reservoir is a drinking-water source for Prachatice, so the water is not used for recreation. Its dam was briefly a border crossing: from 1940 the road over the crest marked the frontier between the German Reich and the Protectorate of Bohemia and Moravia.
