Riverlands: working to restore Cumbria's waterways

Rivers are life forces. They’ve helped sustain ecosystems, cultures and communities for millennia, their quiet power steadily shaping everything from landscapes to place names. But many of our rivers are under threat from climate change, pollution, and human-made changes to the landscapes and waterways, which is why the National Trust launched Riverlands.

The Cumbria Riverlands project stretches from Keswick in the north to Kendal in the south, across the central fells and finally out to sea. It encompasses the rivers themselves, the land which drains into them, and the rich array of wildlife and plants that call these varied habitats home. Together, these make up our ‘riverlands’.

Working with partners, our aim is to restore rivers and catchments to be healthy, clean and rich in wildlife; easily accessed and valued for their heritage and beauty; and with sustainable plans for their long term care.  We’ll post regular updates of the work we’re doing here, on this project timeline, so keep checking back to stay up to date.

A birds-eye view at Acorn Bank

This wonderful footage shows what the newly-completed boulder cascade looks like from the air on Crowdundle Beck, at Acorn Bank.

Carefully constructed, this series of small pools and cascades was built to replace two weirs which were designed to raise the water level to supply the historic watermill. The main weir had suffered repeated storm damage and was at risk of collapse. It also posed a barrier to migratory fish, preventing them from reaching spawning grounds upstream.

The new cascades will support a wide range of river species by offering a variety of freshwater habitats, from faster flowing cascades to shallows and pools. And by gradually rising along its 45m length, it allows migratory fish to pass through, while also maintaining the previous water level at the site of the old weir to allow the mill leat to operate as normal.

This project was funded by the Government's Species Survival Fund. The fund was developed by Defra and its Arm's-Length Bodies. It is being delivered by The National Lottery Heritage Fund in partnership with Natural England and the Environment Agency.
