River Tees fish counts
Monthly and daily counts for salmon and sea trout, recorded by the Environment Agency's fish counter at the Tees Barrage on the lower Tees.
The fish counter at the Tees Barrage only monitors the upstream migration of salmon and sea trout through the fish pass.
Additional routes exist through the:
- main barrage gates
- canoe slalom
- turbine fish pass
- navigation lock
To help fish migrate, since 2014 the Environment Agency and the Canal and River Trust have kept the main barrage gate open as much as possible. When it’s open, around high tide, more fish migrate through this gate than the fish pass. This may explain the lower fish counts recorded since these changes were made.
