Sub-watershed analysis has become a strategic approach in assessment of the natural resources. The guiding principle of this approach is to maximize the benefits of water resources and ecosystems management. This article will present the authors experience in evaluating couple of projects within the UNDP developing program in Prespa region that deals with hydrological analysis and restoration measures. The lake is an interesting case study as regards hydrology and hydrogeology. The lake does not have surface outflow. The waters from the lake outflow through karst underground conduits into Ohrid Lake. Since 1984 the water level declination started and it is still for about 7 m under the long-term average water level. Integrated Management Plan development initiated water balance and rainfall-runoff modeling which base is watershed and precipitation analysis. The paper discus general watershed data and the necessity of delineation based on land use and land cover data (LUC), geological and hydrogeological characteristics.
