About this water

West Cork spate river — tributary of the Lee system. Wild brown trout in mixed geology water. Good fly water through spring and summer.

Hatches & food

EPA freshwater monitoring on the River Sullane confirms a broad food base of mayflies, stoneflies, caddis, aquatic diptera and freshwater shrimp and hoglice across its monitored segments. The records establish presence in the riverbed community rather than emergence timing or a dependable rise.
