Productive areas are found where the stream's character changes. Confluences with smaller tributaries often create nutrient-rich seams and deeper holes. Undercut banks along outside bends are prime lies for larger Brown Trout. The tailouts of pools and the heads of riffles are consistent spots to find actively feeding fish. Areas with significant boulder fields or bedrock shelves create pockets and current breaks that hold trout.
