How to fish it · for Rainbow Trout
When

Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
Very poor — water clarity is working for you, but water temperature is the limiting factor today.
