Henry’s Fork, September 23rd, 2023

A Killing frost is likely on the upper river. Being the first of the season, terrestrial insects in sheltered places are not totally impacted yet and fish will be looking for them. Afternoons will feature BWO and midge hatches, and such as Box Canyon and the Tubs will be great places to try streamers as well as some trying top water fishing because remaining insects. More numerous and severe killing frosts are lined up for the coming days for sure, and as on the South Fork the opposite ends of the effective fly activity spectrum ( BWOs and midges over to streamers and woolly bugger variations.will be increasingly effective for successful fishing.
