Situated south of Cavan town, Lough Sheelin is part of the Inny sub-catchment of the Shannon system, lying north-east of Loughs Kinale/Derragh (site 124) into which it drains. Raised bogs surround the lake and there are two wooded islands. The lake is used for angling.
Lough Sheelin is one of the most important wintering sites in Ireland for Podiceps cristatus (140 birds, 1996), Aythya ferina (635 birds, 1985), Aythya fuligula (1,125 birds, 1996) and Bucephala clangula (219 birds, 1996), which all occur in nationally important numbers.
