If you are in Jackson Hole over the next few weeks, whitewater action is coming on! Flows in the Snake River Canyon are currently rising. Flows through the Snake River Canyon section of the river generally peak sometime between the middle of May and early June. When the flows reach their peak, the best whitewater action of the season is waiting for you. Rafting and kayaking adventures are sure to provide some thrills at this time of year.
The extended forecast seems to hole some warm weather, which should help increase the flows over the next week or so. For more information on Snake River Flows. For more information on Jackson Hole weather.
Be prepared, as water temperatures are quite cool. I would highly advise utilizing a wetsuit.
