The Castleconnell beats on the Lower Shannon, near Limerick and below the Parteen weir, were once among Ireland's great spring-salmon fisheries. The river here is hydro-regulated, and the angler reads the water on the flows he is given. For 2026 it is catch-and-release. Note that the upper Shannon above Parteen carries a separate status. Castleconnell and district clubs hold the water; the State Licence is required.
EPA river-invertebrate monitoring confirms mayflies, stoneflies, caddis, aquatic diptera and freshwater crustaceans are present through this reach's monitored segments. This is food-presence evidence only, not a hatch record, and says nothing about when or how strongly any of these groups emerge on the day.
