VISITORS were given the chance to plumb new depths and explore the ‘fish belly’ gates at Tees Barrage over the weekend.

The event was only possible as the four 50 tonne gates are undergoing maintenance work thanks to a £100,000 project by the Canal and River Trust.

People were able to descend 40 feet into one of the drained gate wells to see the inner workings of the Barrage and the massive hydraulic rams up close, while also learn about fish migration and getting rare access into the control tower to see the brand new digital control system.

Lee Butler, team leader at the Tees Barrage said: “This was a fantastic opportunity for us to give people a rare look at our maintenance work and walk onto the Tees’ river bed.

“The world-renowned white water course was open to visitors, as was the new climbing wall. This really was a chance to come and see the River Tees in all its glory and what it means to the local community.”

A 100 tonne crane has been used to install temporary dams either side of each gate well before removing the water to inspect the gate seals, walls, floor and pivot points, as well as checking the steelwork for damage. Pressure tests will also be carried out on the gates and any corroded components replaced.

The Tees Barrage not only controls the flow of the river but also plays a vital role in preventing the area from flooding.
