How to fish it · for Rainbow
When
Conditions are not ideal but fishable at Lake Britton. Flat calm means fish may be spookier — longer leaders and subtler flies will help. Early morning is often the most productive window in summer — make the most of it.
Where
Start with Parachute Adams (12-18) on a on a floating line. 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 Parachute Adams (12-18) on a on a floating line. 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.

Bank

Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.

About this water

Lake Britton lies in the volcanic country below Mount Shasta, a reservoir on the Pit River system where the water carries the cold, mineral character of that high lava landscape. It holds rainbows and browns, and the mix of inflow and lake means the fishing can shift from stillwater patience to something closer to river work near the moving water. The trout here feed well on the rich insect life the volcanic substrate supports — chironomids and damsels through the season, with mayflies on the calmer water. It's a place that rewards an angler who'll read the conditions rather than force a method on them: where the wind sets the food, where the cool water holds the fish, where the inflow keeps things lively in the warmth of summer. Fish it slow, fish the margins, and pay attention to where cold water enters.
