The Diploma thesis is a project for issuance of a building permit of a small reservoir designed on the plot NO. 234/2 KN in cadastral area of Drsník. The project was drawn up at the request of the investor and according to his requirements. The purpose of the small resevoir is mainly landscape-forming and recreational but it will be use for an extensive fish farming as well. The small water reservoir is to be found on the watercourse of the brook Stržený in the Central Bohemia district approximately 8,5 km south-east of Příbram. Its area is 2457 m2 and its cubic content is 1943 m3 for the normal water level. The dam is designed as a homogenous earth one with the incline on the water side 1:3 and on the air-side 1:2 with the dam crest width 3 m. The drain system is an open runoff with two rectangular walls 2200 mm high and with runoff pipes DN 300. The safety spillway will be placed in the left dam bound and the proposed rate of flow Q100 will be proceded without an overflow of the dam crest
