Římov Reservoir, Reservoir in Římov, South Bohemia, Czechia
Římov Reservoir is a water reservoir on the Malše River near Římov, built between 1971 and 1978 and handed over for use in 1977. Its dam is an earth-fill structure with a core of loess loam, and the reservoir's flooded area extends into the cadastral areas of Římov, Svatý Jan nad Malší and Velešín.
Construction of the reservoir took place between 1971 and 1978, with the dam becoming operational in 1977 to supply drinking water to the region. This development was a major milestone in establishing reliable water infrastructure for the surrounding communities.
The reservoir's name comes from the village of Římov, whose cadastral area the flooded land partly covers, together with Svatý Jan nad Malší and Velešín. The water is a drinking source for about 350,000 people around České Budějovice, so the shoreline is managed to keep the water as high and clean as possible.
The dam is accessible by a road that allows walking across and connects to trails around the water. Wear sturdy shoes as the area is open year-round and surface conditions change with weather and seasons.
During the August 2002 floods, the reservoir passed a peak flow of 476 m³/s, the highest ever recorded there. Because the reservoir holds relatively little water, it cannot meaningfully reduce flooding on the Malše. A small hydroelectric plant operated by Povodí Vltavy now runs at the dam.
