Productive areas are typically associated with specific types of structure. Deep pools, especially those shaded by overhanging vegetation or undercut banks, are reliable holding water. The tail-outs of these pools, where water shallows into riffles, are excellent feeding lanes. Areas with significant submerged timber, fallen trees, and root wads consistently hold fish. Confluences where smaller tributaries enter the main creek often create productive seams and deeper scour holes.
