The results of hydrobiological investigations of Grošnica and Gruža Reservoirs near the city of Kragujevac in Serbia indicated differences in their trophic status. Although considerably younger than Grošnica Reservoir, Gruža Reservoir manifests all the signs of accelerated eutrophication. Primary and secondary plankton productivity is significantly greater in Gruža Reservoir, as is macrophyte production. Accelerated eutrophication also is indicated with the results of an ecological analysis. The manifested differences can be attributed mainly to the greater human influences, as well as the unfavourable morphometric characteristics of Gruža Reservoir, compared to Grošnica Reservoir.
