The seven-mile Smearlagh River, which is a tributary of the River Feale, is formed in the Stack's Mountains and Glanaruddery Mountains from the Broghane Stream, Dromaddamore River, Glashoreag River, and Lyreacrompane River. The Smearlagh meets the Feale at Inchymagilleragh, three miles east of Listowel, where the confluence is known as The Joinings. The Smearlagh is a swift river that provides good salmon and sea trout fishing.
