Lough Currane is the most famous of the lakes in the region and is home to the largest sea trout in Ireland. Atlantic salmon also feature with many of these fish caught in the spring months. The Brown trout are also abundant with the spring period particularly good. Fly patterns, size 8-14 are similar to the upper lakes but the Green Peter and Bibio are dominant on this lake. Bumble patterns are well represented in the catches and Brown and Sea Trout can be taken on similar patterns. A team of three flies on a floating, intermediate or sink tip is the choice for anglers on Currane. Salmon are taken on the fly from March to September with slim bodied hairwing flies preferred. Black Pennel, Hairy Mary, Silver Doctor , Silver Stoat and various patterns of Shrimp Flies are preferred with sizes from 8-14 on a floating line or slow sink tip.
The lake is large compared to the other lakes in the system. It is just above sea level and fish can enter from the Atlantic even in very low water. The famous Butler Pool drains Currane and this fishery holds large numbers of salmon from late June to the end of the season.
The main drifts on the lake are extensive and Sea Trout and Brown Trout are available over the large shallows off Church Island. The eastern side of the lake is strewn with reefs, rocks and small islands and these areas are preferred by sea trout. The areas where the Capall and Cummeragh rivers discharge into Currane are considered a must visit during times of spate.
Salmon are mostly taken on fly near headlands with many famous areas like Capal Bay, Cummeragh Bay, Majors Point, Fur Island, Morgans Rock and Edere Bay producing spring salmon and grilse throughout the season. The best of the salmon fishing is in the spring with April to mid June regarded as the most productive period.
Sea Trout arrive in the system during April and gradually build up throughout the season with the largest run usually occurring during July. Dependant of weather Currane provides exciting fly fishing with anglers not knowing if the next trout to show interest in their flies will be a fish of a life-time. Sea Trout of over 10 pounds are taken each year and the vast majority of anglers practise C&R on these fish.
The Brown Trout are usually taken with the same tactics as Sea Trout but certain areas of the lake appear to hold large Brown Trout stocks notably the western end of the lake with the Castle, Oven Rabbit and Donnellys Bay areas providing excellent sport. Large Duckfly hatches occur at the end of March into April and at this time some large Brown Trout are taken with some up to 3 lbs.
