🌿 GET DIRTY FOR GOOD! 🌿

Join us on Saturday, October 10th for the 2026 Great Willamette Cleanup at Irish Bend Park in Monroe!

Volunteers across Oregon will be coming together to help clean and protect the Willamette River, and Benton County Natural Areas, Parks & Events is proud to partner with Willamette Riverkeeper for an on-land cleanup right here in southern Benton County.

📅 Saturday, October 10, 2026
⏰ 10:00 AM – 12:30 PM
📍 Irish Bend Park
45005 Irish Bend Road, Monroe, OR
💚 FREE to participate!

Irish Bend Park is a favorite summer destination for recreation and relaxation, and now it’s time to give this beautiful stretch of the Willamette a little extra love before the rainy season arrives.

Cleanup supplies and PPE—including trash bags, gloves and grabbers—will be provided. No previous experience is necessary, and volunteers will receive a safety briefing before getting started.

👟 Wear sturdy, closed-toe shoes you don’t mind getting dirty or wet.
💧 Bring drinking water, sunscreen and weather-appropriate layers.
👨‍👩‍👧 Children ages 10+ are welcome with a responsible parent or guardian.

And the fun doesn’t end when the cleanup is over! Volunteers are invited to a Volunteer Appreciation Party at 1:30 PM in Corvallis, featuring drinks, light food and a FREE raffle!

Every bag of trash collected makes a difference. Grab your family and friends and join us as we Get Dirty for Good! 🌎💚

Registration is required—sign up today!

Get dirty for GOOD!

Grab a friend, roll up your sleeves, and join hundreds of volunteers across the Willamette Valley for one big day of action for the river we love.

The Great Willamette Cleanup brings together Willamette Riverkeeper, community partners, and volunteers for on-land and on-water cleanups along the Willamette.
Together, we’ll remove trash, care for our river, meet some great people, and have plenty of fun along the way.

Cleanups run from morning through early afternoon. Then, at 1:30pm, it’s time to celebrate! Join us for volunteer appreciation parties in Portland, Corvallis, and Eugene (locations TBD).

Register for one of our clean up sites today, or contact us about adding your own!

Another great week of Benton County Outdoor Summer Adventures is in the books! 🌲🏹

Campers ages 8 to 12 spent four days exploring the parks and natural areas in their own backyard, learning archery at Adair County Park, stepping back in time at Fort Hoskins Historic Park, casting a line and discovering wildlife at Clemens Park, and identifying native plants on the trails of Beazell Memorial Forest.

Huge shout-out to our partners at . This program is a true collaboration, and we couldn't connect local kids with the outdoors without them. 👏

Want in on the adventure? Find Outdoor Summer Adventures in the Corvallis Parks and Recreation Activity Guide or register at corvallisoregon.gov/parksrec.

🚧 PARK NOTICE – TEMPORARY CLOSURES 🚧

Please be advised that the boat launches and parking lots at Clemens Park, Millcreek Park, and Campbell Park will be closed to motor vehicles this Friday and Saturday for much-needed asphalt maintenance work being completed by a contractor.

To ensure the work can be completed efficiently and safely, parking lot areas will be closed to vehicle traffic only. Walk-in access will still be allowed unless active construction work is taking place.

This maintenance project will help preserve the asphalt and extend its life for many years to come. The work is being funded through Benton County Capital Improvement Funds.

We apologize for any inconvenience and appreciate your patience while these improvements are completed.

Parking alternatives:
• Millcreek Park – Parking may be available near Robinson Grove
• Clemens Park – Limited parking is available near the end of Seely Creek Rd.
• Campbell Park – Access may be very limited due to lack of nearby parking availability

Thank you for your understanding and cooperation!

Spring is showing off in our Willamette Valley prairies right now — that pink wash is rosy plectritis (sea blush) in full bloom. Look closely and you'll spot two Fender's blue butterflies on the wing, a species found nowhere else on Earth but here in our valley.
Protecting and restoring native upland prairie is one of the quieter but most important parts of what Benton County Natural Areas, Parks & Events does. Healthy prairie means lupines for caterpillars, native wildflowers for nectar, and a future for one of Oregon's rarest butterflies. 💙
