Fall Baetis hatching, fish move into tailouts and shallow riffles
Conditions
Cooler weather through mid-September has triggered Red Quills and Fall Baetis on the Big Wood. Fish are moving into tailouts and shallow riffles, feeding hard but remaining skittish, approach with care. Flows are stable at much-below-normal levels, creating ideal conditions for sight-casting to selective trout. Expect clear skies early in the week with rain moving in later; plan your trip around morning and evening windows when light is low and fish are less wary.
