Upper Mesa Falls
Put-in
Sheep FallsSheep Falls is located on a sweeping left turn. Noticeable by a significant horizon line and a hint of spray. Eddie out river right to scout and/or portage. Both the two-tiered part of the drop on the left or the slide on center right are runnable.
Second DropThis rapid is immediately after Sheep Falls. Easiest to scout both while you�re out of your boat, or if you�re portaging�just keep walking. This drop is as intimidating as it is safe. Take note of the two small entrance holes � they�re bigger than they look from the bank. Otherwise, straight down the tongue, baby! Huge, flat pool at the bottom, minimal consequences. Under 1600cfs this drop gets very sticky and isn�t usually run. Over 2500cfs it only gets better! When portaging there are two possibilities for re-entering the river. The best is to slide off a rock at water level into the current right below the meat of the drop. People have seal-launched the high rock, but you run the risk of breaking your boat on the underwater rocks. If you don�t like the look of this: hope you�re wearing long pants. You will be hiking for a while, navigating a steep embankment, and wading through waist-high stinging nettle.
Third DropThis drop is a river-wide, sticky, ledge hole. It can be run anywhere if you have a good relationship with your boof stroke. Otherwise, run left � you can see the drop from the river left eddy. This hole has been known to re-circulate swimmers and empty boats.
Class I if you make it, class VI if you miss. Don�t float over Upper Mesa Falls! Exit river left and smile at the tourists.

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.
