NotesWhat to know before you go
These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.
- Official route corridorHatchery Ford to above Upper Mesa Falls (Sheep Falls Run); About 6.9 river miles
RiverBrain Hatchery Ford to Above Upper Mesa Falls flow recommendations identifies the endpoint chain, river miles, or managed float corridor.
- Public access controlEast Hatchery Ford Boating Site Put-In to Upper Mesa Falls Boardwalk Take-Out
Coordinates represent named public ramps, bank launches, park landings, or an explicitly described staging point.
- Direct live gaugeUSGS 13046000 - Henrys Fork near Ashton, ID
Gauge is on the named waterbody and supplies context only.
- Threshold postureGauge-linked range used for live scoring
The cited route guidance is tied to this gauge and reach; hazards, closures, weather, and local inspection still override the score.
- Safety and land managementCurrent manager notices override this record
American Whitewater rates the reach Class III+(V) and identifies Sheep Falls, Drop No. 2, and The Ledge Hole as hazards. Scout from the designated road/trail and portage any feature that does not have a verified line for the party. Upper Mesa Falls is a mandatory take-out. The American Whitewater access note says to eddy out on the shelf and step onto the boardwalk; missing the exit can commit a party to a waterfall. East Hatchery Ford is the last developed take-out before the falls. Use the direct Ashton gauge only as a flow-planning input. RiverBrain's 600-2,200 cfs recommendation and the route's 1,600 cfs rapid note do not replace inspection of wood, hydraulics, weather, and take-out conditions.
- Camping classificationnearby_basecamp
Use developed Forest Service or Teton Valley lodging/campground options near the endpoints; no on-route canyon camping is assumed.
