Who We Are

We are a 501(c)(3) organization that helps watershed residents work together to improve the health of the Coos watershed. These efforts are rooted in science and driven by the belief that balance between economic and environmental interests is possible.

What We Do

The Coos Watershed Association creates a local, non-governmental network and funding resource so that landowners can easily communicate their issues and opportunities, and explore ideas and techniques for land management and watershed health.

What You Can Do

The Coos Watershed Association accepts donations in multiple forms. You can even donate your time! Every donation you make, big or small, strengthens our watershed by supporting community based education, monitoring, and restoration efforts.


We're hiring!

The Association is seeking a qualified professional to join our dynamic team and become our next Noxious Weeds Specialist! This is a full-time, hourly position with benefits that includes both field and office work. Deadline to apply is February 27; visit for more info.

We've moved!

Holly hack-a-thon happening through February 29, 2024!

This might be our most fun invasive species event yet! The goal is simple: reduce the number of invasive English holly plants in our watershed. To make this more fun, we are pairing up with the woodworking experts at the Oregon Coast Artisan and Trade Education Collective (OCATEC). The winning holly trunk will be turned into something made out of holly wood!


1. Watch the informational video here:

2. Remove the largest diameter holly you can find, using saw or chainsaw. Document the latitude and longitude of the removal site.

3. Trim off all the branches and remove all the berries--it is important that the berries stay with the stump and are NOT transported! (refer to instructions in the video)

4. Bring the holly to OCATEC (64505 Seven Devils Road, Coos Bay, OR, located in the old Charleston School). Look for the Holly hack-a-thon drop-off flyer.

5. Fill out the contact information sheet and attach it to your holly trunk. Place the hacked holly underneath the drop-off flyer.

6. Repeat! There is no limit to the number of entries!

HOW TO WIN: If you submit the holly trunk with the widest diameter, you will be our winner and can choose either a holly-themed wood-working class at OCATEC or a hand-crafted item (both utilizing your holly wood submission!).

PHOTOS: We'd love to get some action shots of you chopping down holly! If you get any, please send them along to
