The main goals in common European environmental policy are the preservation of natural values, biotic diversity and assuring the healthy human environment. Tourist areas, which development is usually based on an intact nature, on the other side represent with their high number of tourists a heavy load on the environment. Lake areas are especially vulnerable and therefore have to be minutely treated and need good working management models. In this graduation thesis a comparison of lake management between Bled and comparable Austrian places is shown. Areas from this region are used because the province of Carinthia (Land Kärnten) has many stagnant waters and also it lies near Slovenia. In the first part of the thesis, a detailed description of Lake Bled is shown; moreover, its main problems are presented there. Because most of the infrastructures have already been built in Bled, problems are more of the organizational and managerial nature. Then, in the second part, the basics of Austrian environmental legislation are shown, with the emphasis on the relation between municipality – region – state. The third part includes the description of the basics characteristics of the Carinthian lakes. In the middle of the previous century, the eutrophication problems emerged in the Carinthian lakes, too. Consequently, they disabled the tourist development, and for that reason the Carinthian government, already in the year 1964, passed a program with all necessary sanitation and remedial measurements. The description of these is shown in the present thesis. Furthermore, the possibilities of financing the environmental projects, which are used in Austria, are also shown. All implemented infrastructures and a quite high number of lakes claim an integral and systematic organizational, managerial and monitoring approach; therefore, the management structure with the description of certain stakeholder tasks is also part of the thesis. Three lakes, which have the comparable morphological characteristics to Lake Bled, and they are also important for the tourist development of surrounding areas, are described in details. In the last part, the comparison with Bled is made (a management model, monitoring results, prices for municipal services) and some solutions for improving the management with our tourist pearl are suggested, above all to improve the communication among the main stakeholders.
