How to fish it · for Rainbow
When
Conditions are not ideal but fishable at Silent Valley Reservoir. The ripple should help fish move and feed more confidently.
Where
Start with Booby (8-10) on a fast strip on floating line or static on sinking. Midday in warm weather — switch to a fast-sink or Di-7 and fish boobies or blobs along the bottom. Rainbows respond to more active retrieves — try short strips between pauses. In the ripple, a bushy searching dry (Hopper, Shipman's, Elk Hair Caddis) outperforms flush emergers — it stays visible and holds the surface tension.
The plan
Plan A

Start with Booby (8-10) on a fast strip on floating line or static on sinking. Midday in warm weather — switch to a fast-sink or Di-7 and fish boobies or blobs along the bottom. Rainbows respond to more active retrieves — try short strips between pauses. In the ripple, a bushy searching dry (Hopper, Shipman's, Elk Hair Caddis) outperforms flush emergers — it stays visible and holds the surface tension.

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

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
