City of Boise Water Jamboree
2025-08-16 11:00 - 15:00 | ID
Celebrate 75 years of keeping the Boise River clean at Ann Morrison Park on Saturday, August 16 from 11 a.m. to 3 p.m. Get your face painted before you hit the river, grab a post-float snack, explore local water and river organizations and jam out to some great music – all in celebration of our city’s gem, the Boise River!
75 years ago, the city built Water Renewal Services to stop pollution of the Boise River, which was, at the time, littered with trash and waste. After building Water Renewal Services, the river started to run clear again and trout returned to our waters, leading to the clean, clear, healthy river that we know and love today.
This event is located in the center of Ann Morrison Park next to the fountain. Parking may be limited.

The 2025 community wide cleanup will be held Saturday, September 20th. Bring your friends, family and co-workers and help clean up the banks of the Boise River. Trash bags and gloves will be provided or bring your own. Trash will be weighed at the end of the event and added to the 2025 total.

Cottonwood Gather and Grow and Nature Walk
2026-06-11 18:00 - 19:00 | ID
“The best time to plant a tree was 30 years ago. The second best time is now.”

Join BREN and help plant a tree for our Black Cottonwood Gather and Grow Project! Each June we collect cottonwood seeds, germinate them and in two years those trees are deployed at the Boise River. Many of the cottonwood trees at the river are at the end of their lifespan or are runners from a parent tree, making them genetically the same. Each BREN tree is genetically unique and increases the genetic diversity of the tree canopy creating a healthier system overall.

We will start with a nature walk to collect seeds and talk about our upcoming project at Kristin Armstrong Municipal Park. Volunteers will then plant seeds in our germination trays. All supplies are provided by BREN, we just need you to show up ready to assist! This event goes from 6-7 pm. We will meet near the picnic shelters, watch for the BREN signs. 500 S Walnut St, Boise, ID 83712
