Sedlice Reservoir, Cultural monument and reservoir in Sedlice, Czech Republic.

Sedlice Reservoir is a man-made lake in the rural village of Sedlice, in the Bohemian region of the Czech Republic, built to manage and treat water before it moves downstream. The dam holds back a wide, open body of water surrounded by low vegetation and fields, with the dam structure visible at one end.

Built between 1921 and 1927 on the Želivka at river kilometre 63.35, the reservoir supplied electricity to Humpolec through the Sedlice hydroelectric plant, whose three horizontal Francis turbines from František Křižík of Prague gave 2,159 kW. The granite dam, designed by engineer Josef Řeřicha and built in 1925–1927 by Ing. Hlava and Dr. Kratochvíl, was declared a cultural monument in 2012 together with its road bridge.

The dam and its road bridge were declared a cultural monument of the Czech Republic in 2012. The bridge, built in the interwar modern style, is 120 m long with ten arches and a granite-cobbled roadway; a preserved relief inscription of the construction firm remains at the Kletečná entrance.

The site sits in a rural setting and is most easily reached on foot or by bicycle from the village of Sedlice. The paths around the water can be muddy after rain, so sturdy footwear is a good idea.

The dam and its road bridge were declared a cultural monument of the Czech Republic in 2012. The bridge, 120 m long with ten arches of 4 m span, carries a granite-sett road and keeps a relief inscription of the building firm at the Kletečná entrance.
