South Fork, September 10th, 2022

South Fork Below Heise Hot Springs

Higher than normal flow (11000 cfs at Irwin,16000 cfs at Heise, 8500 cfs at Lorenzo ) has slowed fishing success. However, unsettled weather is predicted for much of next week. That’s just what is needed to begin the fall mayfly period. It means a big increase in BWO and mahogany dun activity with fish responding accordingly. Also, do not overlook presenting streamer patterns during accompanying low light conditions.

Another “plus” for fishing the South Fork will be the soon-to-begin advance of fall colors along the river and surroundings. So consider taking that camera during upcoming visits.
