Herefordshire TV presenter Richard Hammond has been pictured filming his new show.

He can be seen wading in the water at the Diglis fish pass in Worcester.

The filming was part of his Britain's Beautiful Rivers with Richard Hammond series on Channel 4.

The pictures were shared by Unlocking the Severn, the project responsible for the creation of the fish pass.

The former Top Gear presenter, who lives in Weston under Penyard, near Ross-on-Wye, is fronting the new four-part series that focuses on the River Severn, the Test, Clyde and Derwent, exploring the historical, ecological and economic importance of each.

In the first episode, Hammond followed the Severn from its source in the Cambrian Hills to the Bristol Channel via Worcester.

In the next episode, which will be broadcast tomorrow (Saturday, June 4) at 7.55pm, he travels down the River Test, which runs for 40 miles through the Hampshire countryside, and discovers why this very rare chalk stream is so important to the environment.

What is the Diglis Fish Pass?

The purpose of a fish pass is to allow fish to move past man-made blockages in water. In Diglis, the weir means that many fish looking to travel upstream struggle due to the two-metre separation.

The weir was installed in the 1840s to create a deeper, more reliable pool of water upstream for boats.

Stronger fish like salmon are occasionally able to get past the weir by jumping, but many species do not possess the required strength.

The pass consists of 11 small pools, each just 20 cm higher than the last, making it more manageable for the fish to swim through.

The fish detect the stream of water in the river and can travel upwards, with walls in each pool relieving some of the force created by the water.
