Abstract: The aim of this study was to determine the effect of four hydropower plants systems on the Słupia River. Authors analyzed the daily changes in the water levels, discharge and temperature on the station located about 25 km below the hydropower plants system. Moreover authors determined the daily changes in the levels and temperature of groundwater in the river valley. Based on the measurements it was found that the Słupia River below the hydropower plants system is characterized stable water level (on average, daily changes were less than 0.1 m) and water flow (daily flow variability coefficient about 20%), and the temperature variability (0.5°C during 24 h) was mainly due by climatic factors. Daily changes in groundwater levels averaged out at less than 0.1 m, and the changes in temperature did not exceed 0.2°C. Despite the significant changes in the river valley as a result of hydropower plant construction, after 100 years the favourable conditions allowed to achieve some stability of the ecosystem.
