Productive spots are found wherever structure creates current breaks and depth. The deep pools at the base of waterfalls or steep gradients are prime locations, often holding larger trout. Confluences where smaller tributaries enter the main stream attract fish due to increased food delivery. Undercut banks along outside bends, especially those shaded by overhanging vegetation, provide excellent cover. Riffle-pool sequences are always worth exploring, as fish hold in the softer water at the tailouts.
