Snake River Float

The Snake River Float Project is designed to gain a better idea of what species of mammals, birds, and amphibians use the section of river between Wilson Bridge and South Park. In this section, the river flows mostly through private land where wildlife professionals do not conduct a systematic census.

In two seasons, the Snake River Float project has provided a more complete picture of the species that use the river corridor between Wilson Bridge and South Park. We have also recorded the locations of nests of osprey, bald eagle, and great blue heron, along with ducks and shorebird nesting areas.


Floats take place on Sunday mornings in April – October and spend about three hours on the river.

To the extent possible, floats are scheduled for the same time (date and time) as they were in previous years. Observers need to be trained Nature Mapping volunteers with good bird identification skills and have a second team member to join them. Those interested in participating should contact JHWF Project Coordinator by email or phone 307-739-0968.


Float trips for this section of the river are offered courtesy of AJ DeRosa's Wooden Boat Tours. Special thanks to AJ and his boatmen! For information about Wooden Boat Tours see
