The Kalausis the river in the Stavropolskii region of Russia being an important source of water. Water use has caused water decrease, water depletion and water deterioration. Therefore water shortages exceed natural river flow by 100%. The water quality category is estimated as “very dirty”. The main source of river water pollution is diffuse runoff from agricultural lands. Estimationson both the environmental river flow and the efficiency of water protection measures are given in this paper. It considers the impact of the lands on the flow volume and quality of the river water, and also estimates the impact of global climate change on water scarcity. To improve the ecological status of the river up to “satisfactory” it is necessary to save the volume of environmentally friendly flow without its with drawing. To improve the water quality up to “moderately polluted” it is necessary integrated water protection measures.
