Productive areas are often found where current breaks and structure create ambush points. Target deep pools located downstream of riffles or rapids, where oxygenated water holds fish. Confluences with smaller tributaries are always worth exploring, as they funnel food and often hold a mix of species. Undercut banks, especially those with overhanging vegetation or root systems, provide excellent cover for larger fish. Submerged logs, fallen trees, and rock piles are also prime locations to find both predator and prey species.
