The average depth of the Lough is one metre at both the north and south basins, and is a total area of 4 hectares. It is a well known and important wildfowl area. Many birds take refuge at the Lough, where there is a large population of Swans.
The Lough is also popular for coarse angling. Each year, the bulk of Irish Carp are caught in this lake. The Lough is also habitat to a number of other fish such the Eel, Tench, Perch and Rudd.
The island in the centre of the Lough provides shelter for numerous species of wildlife, attracting many nature lovers.
