Lough Corrib, which is the second largest sheet of inland fresh water in Ireland, is about thirty-five miles in length from Galway to Maam and varies in breadth from eight miles, as between Oughterard and Cong, to one quarter of a mile, as from the Wood of Dun to Corran Point, where it narrows between the Joyce Country and the Iar-Chonnacht hills. Its general direction is from west-north-west, in a curvature, to south-south-east. In depth it varies considerable. It is in many parts full of rocky shoals, dry in summer; and even in the navigation course, having but six or seven feet of water in some places.
