About this water

Wicklow granite spate river with wild brown trout. Flows through wooded Avondale valley. Good dry fly and nymph water when conditions allow.

Hatches & food

EPA kick-sample monitoring on the Avonmore confirms mayflies, stoneflies, a strong caddis assemblage, chironomids and blackflies, plus freshwater shrimp are all present in the river, pointing to a well-fed freestone rather than any single dominant hatch.
