Grand Teton National Park Service U.S. Department of the Interior Grand Teton National Park John D. Rockefeller, Jr. Memorial Parkway Floating the Snake River The River The headwaters of the wild and scenic Snake River are on the boundary between Yellowstone National Park and the Teton Wilderness. Floating the river is complex. A tangle of channels and constantly shifting logjams require boaters to anticipate their routes well in advance. Accidents are common. Please use caution and check conditions before each trip. Flow rates vary greatly throughout the year. They are posted at river landings and permit ofces weekly or when there is a signifcant change. Spring fows are very cold, fast and muddy making the river more difcult. As snowmelt diminishes, volume decreases and water clears. In spite of reduced fow, the current remains deceptively powerful. Strong, upstream afternoon winds may slow your pace. Safety and Etiquette • Prepare boats away from launch ramps to reduce congestion at landings. • Launch when other boats are out of sight, and maintain this interval throughout your trip. • Excessive noise disrupts the river experience for other boaters and disturbs wildlife. Keep silent during wildlife encounters. • Steer clear of other boaters and anglers, including fshing lines. • Rangers regularly patrol the river in summer. Contact river patrol rangers for assistance while foating. • Information and permits are available at the Craig Thomas Discovery and Visitor Center and the Colter Bay Visitor Center. • Carry the following equipment: an extra paddle or oar, a waterproof container with extra clothes, frst aid kit and waste receptacle. Infatable boats should have an air pump, bailing bucket, and patch kit. • Attach all gear securely. • Do not drink river water unless boiled or purifed. • Swimming is not recommended in the river. • For information on Snake River fows, call 1-800-658-5771 or check: waterdata.usgs.gov/wy/nwis/current?type=fow.

The river drops more steeply and the current increases. Complex braiding may obscure the main channel and strong currents can sweep boaters into side channels blocked by logjams. • Moose to South Park Boundary This section of the river is as difcult as the preceding section. Advanced boating skills are required due to fast current, braided channels and logjams. The park extends 5 miles downstream from Moose on the west bank and 2 miles downstream on the east bank. There is no take out or access to the river at the park boundary. The next take-out is at the Snake River Bridge east of Wilson, WY, 14 miles downstream from Moose. • Southgate to Flagg Ranch (Flagg Canyon) Southgate Launch is a half-mile south of the South Entrance to Yellowstone National Park. Flagg Canyon is steep and narrow with challenging white water for rafts and kayaks. Heavy spring water fows create standing waves, haystacks, laterals, and large holes capable of fipping rafts. Scout the river by walking the Flagg Canyon Trail on the west bank of the river. At over 4000 cfs fow the rapids are Class III (not recommended for canoes). Below 4000 cfs, canoeing requires advanced white water skills.

The river winds for 6 miles before reaching Jackson Lake. Depending on the lake level, the trip is another 4 miles to Lizard Creek Campground. Strenuous rowing or paddling may be required. Afternoon thunderstorms and winds produce waves that may swamp canoes. Motors may be used on Jackson Lake. 0 _l Sn ,......I I / L I Moose Landing Craig Thomas Discovery & Visitor Center '-- 1 _ I I ---'Wildlife 26 89 191 ~, ,J r / ,, I I I r::I \ r W " BEAR AWARE • Be Bear Aware!
