The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
In mid-January I visited a spot where a heavily spring-fed tributary feeds into a river without much as much spring flow, creating an area of (in the winter) warmer water where hundreds of brookies were stacked up.
The video quality's as lousy as in all my early videos, but it's still amazing to see so many brook trout in such a small spot.
