This Lough, just north of the Stanegate (an old Roman Road which linked Corbridge with Carlisle), lies between limestone ridges. It is the smallest and shallowest of the four natural loughs located in the Hadrian's Wall area.
The water level fluctuates over a large range, possibly due to drainage through the limestone. This limits the development of marginal vegetation. The Lough can be viewed from the road and is a good site for waterfowl especially in winter. The shooting rights have been leased by the Trust since 1972 as a memorial to Drs. George Jeans and Tom Hird of Corbridge. A number of geese can regularly be viewed including greylag, pink footed, bean and Greenland white-fronted geese. Whooper swans also use the lake, although the water is too shallow for diving ducks. Wading species include snipe, golden plover and black-tailed godwit. Teal, shoveler and wigeon are commonly observed.
