The End of Float Season Cleanup was an amazing success! Stretching from Barber Park to Reid Merrill Park in Eagle across multiple days, 275 volunteers picked up 941 pounds of trash from the Boise River Greenbelt! It is a testament to how much we love this river and our public spaces that so many dedicated people chose to spend their Saturday in service to our community, especially with so many other events going on around town.

Afterwards volunteers returned to Idaho River Sports for the weigh-in of our collected trash and, more importantly, the afterparty! Andrew Sheppard and his band rocked us, 94.9 The River helped us to give out volunteer raffle prizes, Barbarian Brewing quenched our thirst, and community partners joined in the festivities to support the fun!

Thank you to Velocity Clinical Research for making End of Float Season possible as our Headwaters Sponsor of the event, and thank you to Visit Idaho for also supporting us as the Tributary Sponsor.

Most importantly, thank you to our hard-working volunteers – none of this would have been possible without you! The Boise River is a cleaner, healthier place because of you. We can’t wait for next year!

The perfect time to visit the SNRA in the summer and early fall is also when salmon and steelhead are traveling hundreds of miles upriver to spawn here. Endangered sockeye salmon are returning to Redfish and Petit Lakes at this time. Late August and September is spawning season for chinook in the upper Salmon River. The same area is also heavily used by boaters on the ‘day stretch,’ extending from Buckhorn Bridge to the eastern boundary of the SNRA near Wh***ey Flats & Holman Creek.

The SNRA implements restrictions each summer to provide spawning salmon their best chance to successfully lay their eggs in the river gravels.

🚣‍♂️Boaters:

Obey ALL salmon protection signs
Check info boards at launch sites for current info
Watercraft must have ID invasive species sticker
Watercraft must be clean & dry prior to launch
Groups must have one signed float permit.

🚫CLOSURES

Starting 8/15, river closures for all boaters take effect:

from Buckhorn Bridge to Stanley;
from Mormon Bend to Yankee Fork;
from Torrey’s Takeout to eastern SNRA Boundary

🤫Quiet Zones will be in effect at Indian Riffles and Torrey’s Hole:
Always float in the deepest channel
Avoid known redds
Stay in the boat & minimize paddling
Refrain from water play & noise
Don’t build rock dams - it disorients native fish & halts their migration

Starting 8/29, the river is closed between Snyder Springs boat ramp and the eastern SNRA boundary. Floaters will also have a mandatory portage around Indian Riffles.

Starting 9/3, the entire river stretch from Sawtooth Fish Hatchery to the eastern SNRA boundary will be CLOSED to all boaters.

On 9/23, the day stretch of the upper Salmon will reopen to boat traffic.
