On, in or under - our work is all about the mighty Tees, improving, enhancing and enjoying this fascinating river. The Tees Rivers Trust has been established to protect and enhance the environment of the River Tees and its tributaries. The charity is involved in activities to improve the rivers, streams, watercourses and water impoundments of the catchments of the river Tees and its tributaries. In particular, work has been undertaken to deliver advice and capital works on diffuse rural pollution and invasive species control at a number of locations. The charity has also delivered River lab projects into local schools.
