Last light provides just the advantage that big redside Deschutes River trout thrive on. This minimal light environment creates a safe choppy top nutrient enrich feeding ground next to the grassy river banks. Large salmon flies who spend most of their day hanging out on trees, river grass, and sage take flight when the late evening temperatures soar. Their newly fertile eggs are released into the filmy rivers surface often causing the big bug to crash into the water turning into the perfect pray for a hungry trout.
