Sažetak

The river Sutla (Sotla) forms the border between the Republic of Slovenia and Republic of Croatia. The Sutla Lake (Vonarje reservoir) of 12.4 million m3 was built and filled in 1980 as drinking water supply and for flood protection. Immediately after filling, the reservoir showed extreme water quality problems, degradation of the water use. Due to high risk for the humans and the environment that has hardly been managed successfully, the reservoir was drained in 1988. Now it operates as a dry retention basin for flood protection. Over the past decade, the area of the Sutla catchment has developed touristically. Nowadays, there are many local and regional initiatives to fill the Sutla Lake with water again and to build tourist and recreational facilities. There are also initiatives to use water for irrigation and as a drinking water supply. All of the stated facts indicate an urgent necessity to improve the water quality of the river Sutla and to redefine the Sutla Lake as a multipurpose lake. We propose a conceptual framework for water quality management and design of the mathematical model for the river Sutla water quality with emphasis on the Sutla Lake.
