Abstract: At present, many existing dams in Estonia are mostly recreational purposes, and most of them have been now largely decayed or lost their original functionality. The man-made structures in the river basins are changing the hydrographs of natural streams and therefore directly affect the local ecosystem and its biota. The condition of these structures on estuarine rivers and their use, can adversely affect coastal areas and aquatic life, e. g., due to the fish migration. Many Estonian rivers end their streams at the Baltic Sea and thus affect the coastal processes (Laanearu et al, 2007) and are also important in transport, energy and agricultural use. The study focuses on the environmental engineering projects hydraulic performances of some dams in Estonia. There are more than 1,000 dams (Estonian GIS data of dams on the territory of Estonia) at the Estonian rivers.
