After only one field season, HFF’s study of habitat use by adult rainbow trout has provided statistically meaningful descriptions of the role of aquatic plants (called macrophytes by biologists) in providing trout habitat in the Harriman State Park reach of the river.
Fifteen local kids experienced fly fishing on their local Henry's Fork at the end of August thanks to eight incredible guides who donated a day to the kids as part of Youth on the Fly.

We began a study this spring that will help reveal what kind of habitat trout seek in the famed Ranch section of the Henry’s Fork. A thorough assessment of trout habitat at 180 random points in the Henry’s Fork between the upper Harriman State Park boundary and Osborne Bridge showed ideal water conditions.
Rainbow trout in the Box Canyon reach of the Henry’s Fork are more abundant this spring than in any year since the 1970s. Based on sampling conducted in mid-May, Idaho Department of Fish and Game (IDFG) biologists estimate the population at just under 6,200 fish per mile, plus or minus 500.
