In the years 1972-1989 and 1995-2005, water levels were recorded daily and water discharges were measured twice a month in a small stream running in the Odra river valley parallel to the river channel. The observations and measurements were made in three gauging sections: an outfall on the stream stretch fed from the river channel upstream of the damming weir, an outfall on the stretch drained by the river downstream of the weir, and a gauging section on a neighbouring stream not affected by the river channel. The study determined the mean annual and semi-annual (summer and winter) discharges and specific discharges. The results confirmed that the water levels in the river have a considerable influence on the discharge in the stream flowing through its valley.
