River Drish

River Drish venue image

The Drish is one of the Tipperary rivers nobody much writes about — small, freestone, running through farm country with more wild brown trout than it has any right to.

About this water

You can have it entirely to yourself on a Tuesday in May, which is either a sign that the rest of the world has overlooked something or simply that you've been paying attention. The fish are modest, the access is simple, the afternoon is yours.

Hatches & food

EPA freshwater monitoring on the River Drish confirms mayflies, caddis, aquatic diptera and freshwater crustaceans (including hoglice and, notably, white-clawed crayfish) are present, with stoneflies recorded more sparsely. This is food-presence evidence from kick samples, not a confirmed hatch pattern.
