Stradbally Lake in County Laois is a charming 6-acre brown trout fishery set within the grounds of Stradbally Hall, surrounded by fully matured wildlife and natural islands that serve as rich sources of insect life and fly food for the resident trout. The lake has undergone extensive restoration work, transforming it into a well-managed and productive angling destination. Beyond the lake itself, the broader Stradbally River catchment drains approximately 118 square kilometres of predominantly pasture and arable land, with peat bog more prevalent in the upper reaches. The underlying geology consists primarily of limestone and shale, with some sandstone in the upper catchment — a composition that shapes the river's character and the habitat it provides for fish. The Stradbally River joins the River Barrow main channel approximately 1.5 kilometres southwest of Vicarstown, and its significant tributaries include the Crooked and Timahoe rivers.
