Middle Sacramento River Salmon and Steelhead Rotary Screw Trap Monitoring

Description / purpose

CDFG uses Rotary Screw Traps (RST) sampling to quantify emigrating juvenile salmonids by counting the number of fish captured within a known volume of water passing through the RSTs over time. Regular trapping is implemented and reported from Tisdale Weir and Knights Landing. These are the primary sources of data for salmon emigrating from the Sacramento River. There are approximately 30 other RSTs that operate in California, but these two are the prominent and consistent Sacramento River traps.
