Sažetak
The aim of this paper is an analysis of hydrological measurements obtained in Blue Lake located near the town of Imotski (Croatia), in the period between 6 November 2009 at 10:26 h to 4 September 2010 at 03:26 h (7230 h or 302 days). The water depth, water temperature and electrical conductivity of the water was continuously measured during this time. The measurements were obtained with the CTD DIVER (Schlumberger Water Services). The instrument was fixed at the bottom of Blue Lake, which means that all the measured data refer to a single point of measurement. The measured data present the first systemized and continuous monitoring of the hydrological parameters of this fascinating karst phenomenon. The hydrological analysis also involved the daily rainfall data and daily average air temperatures recorded at the nearby Imotski meteorological station. The intensities of the water level rising and falling, as well as hourly and daily average inflow and outflow into and from the lake, were calculated using the obtained data. The analysis led to the conclusion that Blue Lake is mainly recharged by the water coming from the karst aquifer, the dimensions and characteristics of which have not yet been studied well enough.
