Flowing 18 km and nestled between Windermere and Kendal, is the River Gilpin.

The River Gilpin joins the River Kent SSSI/SAC before reaching the estuary and into Morecambe Bay. Agricultural pressures and barriers to fish migration are identified as key factors contributing to water quality decline here and limiting access to vital habitats within the Gilpin catchment.

Although there are only two weirs on the river, they obstruct migratory routes and negatively affect fish populations. The removal of Starnthwaite Ghyll weir, the furthest upstream, will restore access and connectivity to upstream habitats. This includes valuable spawning and refuge sites for species, such as the Atlantic salmon and brown trout. This Open Rivers Programme, funder of the project, is a grant-giving organisation that offers grants to support projects that lead to the removal of small dams and the restoration of river flow and biodiversity.

The weir

Standing 1.75 metres high by 12 metres across, removal of this barrier will enhance migration success, particularly for species journeying to the sea. The weir, built in the 1930s to provide power to the local school, no longer serves its original purpose. Weirs were historically constructed without consideration for the environment, including natural river processes, form and function. Following its partial collapse, further deterioration has become a risk to surrounding properties. Removing this barrier in a safe and controlled manner will not only eliminate liability for landowners but also reduce potential risks to the wider community.

This will be the first weir to be removed on the River Gilpin. It has received considerable support from the local community and the structure owner following several months of engagement. The initiative will complement proposed mitigation efforts at the downstream barrier, facilitating migration along the entire watercourse.

This weir removal alone will open up 13.5 km of additional habitat for priority species, enhance local biodiversity and supports the local community by addressing risks to nearby properties.

SCRT are hoping to remove the weir in summer 2026.
