ABSTRACT
During the last century the Macro Lake Prespa experienced a significant water level fluctuation. After its last peak (1963) and after the separation of the Micro Lake Prespa (1975), the level generally dropped by approximately 8 m (2002). This resulted to a loss in water volume and even more significant a loss of water surface. The effects and causes of the changes in the Lake have been investigated in various studies carried out by interested parties from shareholding countries. Most of these studies had to rely on the hydrometeorological data that were not up-to-date or not complete. In this study, effort was made to collect long-term time series climatic and hydrological data and to assess the vulnerability of Lake Prespa to climate change and human actions in the watershed. Monitoring network and data quality and quantity is also discussed in the context of hydrological modelling and transboundary collaboration in integrated water resources management. Hydrological analysis is obtained using measured data for the period (1951-2010) at Pretor meteorological station and Stenje hydrological station.
