Sažetak
Lake Vrana on the island of Cres in the Croatian part of the Adriatic Sea is one of the largest fresh water features on Mediterranean islands. The paper provides an overview of groundwater and lake temperature measurements to date and recent activities within the project “Climate Change and Impacts on Water Supply” (CC-WaterS, SEE-TCP). Groundwater temperatures measured in boreholes are almost constant throughout the year, mildly dropping according to the depth, in the range from 14.6 to 13.1 °C. The temperature of the lake water changes throughout the year, and extreme thermal stratification occurs at the end of summer. In the water layer above the thermocline, water temperature can reach up to 25 °C or more. At the same time, based on conducted measurements, water temperature is very low in the hypolimnetic area and, depending on annual climate characteristics, ranges from 6.5 to 9.3 °C. In the isothermal period, which lasts from 2 to 3 months, the whole water mass has a homogenous temperature within 4.65 to 8.9 °C recorded range. Earlier collected data of lake water temperatures are rare and insufficient for analyses of a potential impact of climate changes.
