A north Sligo spate river with a stronger limestone influence than most west-coast systems — the Carboniferous bedrock moderates its flashiness, improves water clarity recovery after rain, and sustains better insect life than typical blanket-bog drainages. Salmon and sea trout run from June; grilse dominate. Local club-managed access, with day permits available. The town of Easkey has a functioning angling infrastructure. Worth choosing over some smaller Connacht rivers precisely because the limestone backbone makes it more forgiving of marginal conditions.
