Eutrophication is one of the main problems of water deterioration in accumulation lakes. Phosphorus is considered as the key factor for eutrophication of lacustrine water. Its concentration in lakes originates from external input and the emission from the sediment. It was necessary to determine the substrates of phosphorus by sequential extraction in order to determine the dynamics and bioavailability of phosphorus. On the basis of results obtained the proposals for the preparation of land were made in order to minimise the input of phosphorus.

In the frame of the project Revitalization of the Big DTD Canal and preparation for introducing modern wastewater treatment plants for the towns and industry in the Backa region, an all-inclusive program has been prepared for monitoring quality and quantity of water in the Big Canal and pertaining lateral canals. The paper presents results obtained for contents of nutrients (N and P) that indicate a poor quality of the Canal water, especially in the segment from the triangle to the hydrological node Vrbas. In many cases, measured concentrations of nitrogen and phosphorus were several times higher than maximal tolerable levels, so that it is necessary to undertake urgent measures with the aim of preventing further degradation of the Canal water, and eventually its revitalization.

Nitrogen and phosphorus contents in water, sediment and shoots of Phragmites communis Trin, and Typha latifolia L., as possible indicators of trophic state were used in the area of the Bardaca fish-pond. The results of total nitrogen and phosphorus contents during growing season indicate the hypertrophic state of waters in all locations.
