The Canal & River Trust are responsible for the 22 miles from Worsall, (the highest tidal point in the river until the barrage was built) through Yarm and up to and including the iconic Tees Barrage in Stockton-On-Tees.
The River Tees was formed over 18,000 years ago during the Ice Age and has always been at the heart of Teesside. Since medieval times it's brought trade and prosperity, firstly to Yarm and later with the Industrial Revolution to Stockton then Middlesbrough.
