31st Annual Celebration
2026-05-28 17:00 - 20:00 | Kaul Auditorium, Reed College, 3017 SE Woodstock Blvd, Portland, OR 97202
This year, we gather to celebrate The Current That Carries Us.
For more than 30 years, Walt Mintkeski was a guiding force behind community-led restoration in the Johnson Creek watershed. His steady presence, deep care, and unwavering belief in people power helped shape the creek and the community we know today. Walt was the current that carried this work forward.
With his passing this winter, we feel both the weight of loss and the strength of what he set in motion. Now, each of us is called to step into that current, to carry this work forward together.
Join us for an evening of remembrance, connection, and purpose. Celebrate Walt’s extraordinary legacy, bid on beautiful local nature art in our silent auction, take part in a playful wine pull, and raise your paddle to support the new Walt Mintkeski Stewardship Fund.
Together, we will honor the current that carried us here and become, each in our own way, the current that carries this work forward.

>>PURCHASE YOUR TICKETS HERE<<

When: Thursday, May 28, 5:00 pm – 8:00 pm
5-6 pm Social Hour

Art Gallery Silent Auction (Nature Art by Local Artists)

The Leach Botanical Garden is a hidden gem in outer SE Portland. Beyond the manicured paths of the garden are several acres of forests and fields which have become overrun by Himalayan blackberry, English ivy, and other plants that discourage diversity. The garden needs your help to become a healthy ecosystem again!
