South Fork, August 15th, 2020

Look at the boat ramp-parking areas. A glance at these tells how good the fishing is (for example Spring Creek overflows to near the highway during daytime). Mayflies, early morning mutant stones, PM caddis and terrestrial insects are active. Have patterns for all of these, and you will find action. At 9800 cfs at Irwin, 10700 cfs at Heise and 4850  cfs at Lorenzo, the river could not be in better shape.
