Grand Teton National park is warning that shifting channels and numerous logjams have created difficult and unpredictable conditions on some of the side channels of the Snake River between Pacific Creek and Deadman’s Bar; especially just downstream from Spread Creek. River rangers urge boaters to utilize situational awareness and understand their personal skill levels prior to navigating from the main channel along this stretch of the river.
They point out that hazards can develop at any location and at any time, and obstructions are subject to a high degree of change. As such, boaters should anticipate their routes well in advance. Only boaters with advanced skill levels should attempt sidechannels due to swift water, multiple braided channels and numerous obstructions.
Sight lines are short and channel options that existed hours before may be blocked. The Park reminds that floating the river is complex, and recent logjams have made this section of river challenging. Boat operators may need to stop the boat to scout, and possibly choose an alternate route.
