SCRT, Environment Agency, Natural England and EU LIFE IP ‘Natural Course’ worked together on the Jumb Quarry project as part of the Cumbrian River Restoration Strategy. The project removed 9000 tonnes of mine spoil from the east Kentmere valley just south of the reservoir. The spoil heaps were the result of slate mining which ceased in the mid 1960’s. They continued to be a problem providing high sediment loads resulting in a concentration of sediment deposition in the river channel where the height of the river bed has increased as a result of aggradation. Long term maintenance was necessary to reduce and prevent flooding downstream.
