The Carrowbeg River is a short, intimate river flowing directly through the heart of Westport, County Mayo, in the west of Ireland. It empties into Westport Bay, which is part of the larger Clew Bay complex. The river is a charming urban fishery that offers accessible angling in a scenic town setting, making it particularly well-suited for beginners and younger anglers looking to develop their skills. The river is stocked annually, which supplements the resident wild brown trout population and improves angling opportunities throughout the season. An impassable weir at the lower end of the river prevents migratory fish such as salmon and sea trout from entering, meaning brown trout is the sole target species for anglers on this water.
