Project description

Removal of weirs to improve fish passage and enhance upstream channel

Part of ColnCAN's Weir today:gone tomorrow programme, this project was managed by Spelthorne Borough Council & the Environment Agency and was completed in August 2016. The work included Weir notching, installation of a new control structure on an inlet to an inline lake and habitat restoration along a 600m section of the river.  The weir notching reduced the impounding effect on the reach upstream, improved fish passage for all species and enabled a natural river characteristics to be restored.
