Abstract

In the Siret and Prut river basins, wich are overlapping historical province of Moldova, the artificial lakes dominate over natural ones. Some ponds are historically recorded during Ştefan cel Mare princehood 1457-1504 (Dracşani). This study examines and highlights the role that these lakes have in the present economic activity of local communities and reveals the current degree of pollution after the industrialization.The highest density of lakes is specific for the northern part of Moldavian Plateau (Botoşani and Iaşi counties). In the mountain area were analyzed lakes with a high degree of complexity and natural dam lakes (Roşu, Crucii). Salt lakes were avoided because the physicochemical characteristics are quite different and can not be used in the water supply system. The majority of the lakes, depending on the nutrient content, belongs to the eutrophic and hipertrophic category, and from the biological point of view are oligotrophic, mesotrophic or eutrophic. All artificial lakes have complex functions, even if are ponds or hydropower complexes.

Keywords: genetic type, lakes, Moldova, pollution, water quality
