Hatch Status

You may see Flavs and fall Baetis during the day, along with a few crane flies skittering about

Conditions

Ideal wading conditions persist on the South Fork through the last week of September, with flows holding at 300 cfs and water temperature at a prime 53 degrees. Evening caddis activity remains strong throughout the day, while Flavs and fall Baetis will keep you busy during afternoon hours. Partly cloudy skies and calm winds support excellent fishing prospects across the week. Consider bigger attractors near the edges as flows settle into this stable pattern.

Techniques

  • If bugs are scarce, try a hopper dropper rig, deep nymphing with a bobber, or Euro style
