The dependence of the primary production and destruction of organic substances in the water bodies of the Dnieper mouth zone on their external water exchange was determined. The volumes of discharge released through the dam of the Kakhovska HEPS was estimated. The quantitative evaluation of the balance of self-contamination and self-purification and the trophic level of water bodies during different periods of water exchange and at different discharges released through the Kakhovka dam within the range of 300−1750 m3/s were evaluated. It has been shown that the discharges within 650−1250 m3/s are optimal in terms of water quality forming processes and providing the high biological productivity within water bodies of the Dnieper mouth zone.
