How to fish it · for Rainbow
When
Current conditions suit Lee Reservoirs (Inniscarra & Carrigadrohid) well for summer tactics. The ripple should help fish move and feed more confidently.
Where
Start with Bibio (10-12) — on the bob / top dropper. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Bibio (10-12) — on the bob / top dropper. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

Fish early and late, try deeper during the heat of the day with a fast-sinking line.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Either bank or boat

Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

About this water

One of the best documented Irish pike-fly venue systems, with active guide services and reported fly-caught fish. Two ESB reservoirs on the River Lee west of Cork city — Inniscarra (larger, deeper) and Carrigadrohid (smaller, shallower). Both hold big pike and offer excellent fly-fishing opportunities from boat and bank. The sheltered valley location means they fish well even when exposed loughs are blown out.

  • Reservoir
  • Mixed
Why this score
  • Wind conditions (ripple) closely match what this water fishes best in.
  • Temperature (cool) is in the sweet spot for summer fishing.
  • Murrough is in its seasonal window, boosting the chance of targeted feeding.
