Lučina Reservoir, reservoir in Mýto, Czech Republic

Lučina Reservoir is a drinking-water reservoir on the Mže in the Český les, about five kilometres west of Tachov. Its straight embankment dam, 183.5 m long and 23.5 m high, is built of local gneiss rubble with a reinforced-concrete facing on the water side; the bare stone fill shows on the downstream slope. The water surface covers 86.2 hectares and reaches 2.42 km up the valley.

The dam was built between 1970 and 1975 on the Mže at river kilometre 96.35, on the border of Tachov and Halže. The village of Lučina, on the right bank slopes, had not been fully resettled after the expulsion of Germans and was demolished for the reservoir. The reservoir supplies drinking water to the Tachov, Bor, Planá, Stříbro and Kladruby areas.

The reservoir is named after the village of Lučina (German: Sorghof), which stood on the slopes of the right bank and was demolished for the dam; it had never been fully resettled after the expulsion of Germans from Czechoslovakia. The reservoir supplies drinking water to the Tachov, Bor, Planá, Stříbro and Kladruby areas, and bathing and boating are prohibited.

The dam lies on the Tachov–Halže municipal boundary, 5 km west of Tachov, with the water body running 2.42 km northwest past the mouths of the Sklářský and Lužní streams. Bathing and boating are prohibited because the reservoir supplies drinking water. The dam crown is 4 m wide and 183.5 m long.

The brown tint of the water comes from peat bogs in the catchment area of 104.7 km²; the average annual flow into the reservoir is 1.09 m³/s. Since 1996 two Bánki turbines in the lower outlets have generated 150 kW of electricity.
