Clare limestone trout river with excellent populations of wild brown trout. Spring-fed and consistently clear — you can see every fish. The limestone enrichment produces superb mayfly hatches from mid-May. Good dry-fly fishing from April onwards. Sight-fishing is productive on calm days. A technically demanding limestone river that rewards observation and accuracy.
Hatches & food
EPA river-invertebrate monitoring on the Fergus confirms a broad food base of mayflies, stoneflies, caddis, chironomids and other aquatic diptera, and freshwater crustaceans across its monitored reaches - presence only, with no evidence of hatch timing or a visible rise.
