As is happening on the South Fork, BWOs and mahogany duns are showing up and down the river whether in the Last Chance-Harriman section or the lower river. The best fishing on the lower river at present seems to be in the Warm River to Ashton section where streamer fishing is bringing responses from large brown trout as a result of the unsettled weather conditions. Rely on terrestrial insect patterns being effective during sunny days anywhere on the river. Look for streamer fishing to be increasingly effective almost everywhere on the river as we advance into the fall season.
Flow out of Henry’s Lake has been essentially cut in half as storage begins. Thus fish in the Flat Ranch reach move downstream into the Henry’s Fork proper. This will make streamer fishing very effective in “The Tubs” area, especially early and late in the day. Some of the largest Henry’s Fork whitefish populate this part of the river. If you are looking to supply fish for the smoker, midge and BWO life cycle patterns really interest these salmonids residing here in good numbers.
