Cumbria catchments include: Derwent North West, South West Lakes, Kent and Levern Catchments. In contrast to some of the more urbanised areas of the Natural Course project, Natural Course will need to consider the Special Areas of Conservation and Sites of Scientific Interest when finding solutions to improving the water quality in Cumbria.

Well known for its agriculture, mountains and lakes, Cumbria has high pressures from tourism and contains remnants of its industrial heritage and mining industry. Much of the water is extracted for public water supply, agriculture and industry, and is distributed and used across the North West. Cumbrian catchments are also home to important wildlife populations including, salmon, otter, lamprey and fresh water mussels.

With a growing population and increasing flood risk, the catchment hosts will be working with key partners and community groups to protect the water environment in the area for future generations.

The Derwent catchment is hosted by West Cumbria Rivers Trust. The Kent and Levern Catchment is hosted by South Cumbria Rivers Trust. Both South Cumbria Rivers Trust and West Cumbria Rivers Trust host the South West Lakes Catchment.
