Henrys Fork

The Ashton gage is the ACCEPTED gage for this run. There is not a 'correct' gage. The Island Park gage does not include the flow from the Buffalo Fork (which is often larger than the Henrys Fork itself at Island Park). Theoretically, the flow from the Island Park gage could be added to the flow from the Buffalo Fork. The problem is that the gage on the Buffalo Fork is above the confluence with Lava Creek. Lava Creek does not have a gage, but guessing by the picture above, it might be significant. The problem with the Ashton gage is that it also includes the flow from the Warm River.
