Abstract
The paper analyses the series of average daily, monthly and annual discharges of the Jadro River source measured at three hydrological stations (Jadro-Majdan, Jadro-Novi Kanal, Jadro-Dioklecijanov Kanal) in the period from January 1, 1995 to December 31, 2021. The main goal of the research described in this paper was to compare the quantities of water abstracted from the Jadro source into the water supply system in the period 1995-2009 with those in the recent 2010-2021 period. There has been a positive shift in the past 12 years, i.e. on average, less water is annually abstracted from the Jadro source than in the period 1995-2009. It is important to note that the downward trend in the recent period is statistically significant. It is also important to note that the problems still exist, primarily because the situation during the warm period of the year from June to September has not significantly improved. The key problem occurs in July and August, when more than 40% of the water from the source is still abstracted. It can be realistically expected that the air temperatures in the region will rise in the future as a consequence of global warming. Drought occurrences will intensify during the summer and periods without rain, which could result in a renewed increase in water abstraction from the Jadro source. It is necessary to continue the work on reducing the irreversible removal of water from the source and creating a reliable and a sustainable management system for this invaluable water resource.
