Norfolk river trout given help to reach spawning ground

The River Nar
Three 30cm high ramps of rock have been built downstream of the weir

Fish in a river in Norfolk have been given a helping hand to migrate to hard-to-reach spawning grounds.

Brown and sea trout, which have seen a UK-wide decline, have found it difficult to navigate a metre-high (3ft) weir at Pentney near King's Lynn.

The Environment Agency and the Wild Trout Trust have spent £10,000 on special ramps to help the fish.

Three 30cm (1ft) high ramps have been built downstream of the weir, using 140 tonnes of clean rock and gravel.

Fisheries technical specialist Chris Bell said: "The River Nar has brown trout as well as small numbers of sea trout which enter the river at King's Lynn.

"These fish need to reach the gravel beds of the upper Nar where they spawn.

"We've worked together with local landowners and our project partners, the Wild Trout Trust, to enable them to do this much more easily."
