Like the other Lake District lakes, Bassenthwaite Lake lies in a glacially eroded valley, left after the last glaciation. Bassenthwaite Lake is linked to

plain between the two lakes. There has been speculation that Derwent Water and Bassenthwaite Lake were once one larger lake with the alluvial flats now separating them formed from partial infill of the original basin.

Biodiversity

The lake's catchment is the largest of any lake in the Lake District. This, along with a large percentage of cultivable land within this drainage area, makes Bassenthwaite Lake a fertile habitat. The lake contains

Threats

Water quality is adversely affected by high sediment deposition, and there are other problems such as phosphate pollution. These issues are being addressed via the Bassenthwaite Lake Restoration Programme. To reduce the sediment entering the lake more trees have been planted alongside watercourses, and clear felling of existing tree cover has been discouraged with the cooperation of

Works to upgrade the wastewater treatment works and pumping station were begun in May 2010.
