Fishing Conditions

April 12, 2021

The Gallatin has been fishing well. Due to some cooler temps and nights, the river is a nice greenish color and flows have been consistently at or below 400 cfs. Midges and some occasional BWO's (as water temps increase and when conditions are right) can be spotted throughout. Sub-surface fishing will continue to be the most productive tactic. Lead with simple a stonefly pattern like a pats rubber legs or delektable hurless and trail behind a midge small pheasant tail, purple spanker or even a dirt snake. Maybe just a little early yet but try to keep an eye out for those spawning beds, it's good practice to avoid disturbing those areas.
