This short rivers drains Coniston Water and enters the Leven estuary at Greenodd. Being lake fed it is invariably clear even during periods of high flow and holds its level far longer than the neighbouring spate rivers.

The river is not noted for its trout fishing, the main interest being sea trout and salmon. Stocks of both have declined substantially over recent years and salmon numbers are below conservation levels. As a result there is a currently a mandatory catch and release ruling in place for salmon.

Access for casual visitors is virtually non existant with all the river in private or syndicate hands. Penny Parrock Angling Club Ltd have water on this fishery.
