Limnological characteristics, water regime and water quality problems of Borkovac reservoir (Vojvodina, Serbia)

Abstract

In this study we present interdisciplinary investigations of the Borkovac reservoir (Vojvodina, Serbia). The limnological characteristics of the reservoir were analysed in the scope of its sustainable use for irrigation, fishing and tourism. This multipurpose water accumulation has been established in 1975 as a part of regional hydrological system of the Fru{ka Gora mountain region.The main environmental problems recognized in this study were: water regime, intensive sedimentation in the reservoir, enhanced water eutrophycation and toxic cyanobacterial blooms. Observed environmental problems and proposed solutions in the case of the Borkovac accumulation including construction of the sediment precipitator at the Borkovac stream junction to lake, sediment removal, artificial water mixing and oxygenation, phosphorous inactivitation, different kinds of biomanipulations and biomass removal and introduction of ecoremedation methods could also be applied to other artificial water bodies of the Fru{ka Gora slopes.

The phylosophy and applicability of ecoremediations for the protection of water ecosystems

“…Due to constant increase of the total capacity via the increased saprobity, one of the most extreme consequences -the algal bloom is most probable, when the rapid multiplication of algae results in their visible apperance on the water surface (Bellinger and Sigee 2010). Blooming cyanobacteria might be very hazardous for whole ecosystem, but specially endangered are humans supplied with drinking water produced from blooming reservoirs and lakes (Svir~ev et al 2009;Svir~ev et al 2010;Dolinaj et al 2011).…”
