The Lososina River is one of the Polish Carpathian mountain streams that crosses the south of the Beskid Wyspowy Mountains. It is mostly gravel-bed, it is flashy, experiences frequent flooding and often causes trouble for the local communities as far as spring floods are concerned. At the mouth of the Lososina River there is one of the biggest Polish Carpathian artificial lakes-the Zywiecki Water Reservoir (ZWR). Since the Lososina River transports mostly gravel as the bed load to the ZWR, in the early seventies it was partly canalized, especially in places where it passes the inhabited areas. The situation of the Lososina River before and after the engineering works is compared. Features such as changes in cross-section geometry, slope, granulometry and bed load transport balance were compared using archives and present-day studies. For the purpose of the study, old engineering projects and reports were used to find out the difference in the Lososina River behaviour.
