Karelia has a well-developed hydrographic network, which has about 27 thousand rivers and 61 thousand lakes. The modern use of water bodies is accompanied by their qualitative and quantitative transformations. Now the territory of Karelia consists of more than 20 reservoirs, they represent about 40% of the lake's area. The creation of reservoirs has not resulted in substantial flooding of land, under water employed just over 1% territory. There were no significant changes in hydrographic network. However, the creation of reservoirs significantly changes in the natural water regime (hydrological and hydrochemical). The objective of our follow-up work just is to see how influenced the creation of reservoirs of Karelia to the main components of nature.
