The master's thesis deals with the area of the drained Vonarje reservoir, which was built in 1980 and then, due to the poor quality of retained water, emptied in 1988. After 2005, many interest groups became interested in the area in order to revitalize the area and locate activities. The purpose of the paper is to present and compare three proposals of the most frequently expressed scenarions: ornithological nature conservation proposal (lake level at 200.0 m above sea level), tourist and recreational proposal (lake level at 204.0 m above sea level) and water proposal (lake level at 209.35 m above sea level) mnv.). Based on the analysis and comparison of the proposed proposals for floodplains and collected professional articles, most of which support the smallest lake, an ornithological nature conservation proposal is selected in this paper for further design of the Vonarsko Lake area. For spatial planning, a project program with reference examples and main directions is first determined, which contains mainly educational research activities and certain forms of tourist and recreational activities. Five locations of program areas are determined by analysis, inventory and field visit: 1. Akel: area of alternative habitat, 2. Breznica: area of ornithological park and area of Center for school and extracurricular activities, 3. Paklec: area of research and interpretation center, 4. Brezno : wetland area at the inflow into the lake and educational recreational area and 5. Vonarje: tourist recreational area. The program areas are interconnected by a system of walking and themed trails.
