September 2026 | Columbia Slough Watershed Council News | | |
Greetings!
Bats, birds, and mermaids — oh my!
August was a busy month here at the Council, filled with opportunities to get outside and connect with our local waterways and wildlife. We hosted bat walks, joined the Bird Alliance of Oregon for a birding paddle, and brought back a beloved annual event: our film photography workshop.
And what’s this about mermaids, you ask? A local secret, Mermaid Cove can be found by paddling east from the Whitaker Ponds boat launch. Continue reading below for more details on this hidden wonder!
School (including Slough School) may be back in session, but we hope you find time to explore somewhere new to you, including Mermaid Cove, and join us for one of our many events this September. We have tree walks, a group run, forest bathing, and more!
See you outside!

If you've paddled with us at Whitaker Slough before, you know we always take a left, to the west, out of the dock. But now you can go right and explore a magical place called Mermaid Cove!
Through word-of-mouth from community partners about what it was once like, Council staff heard stories about ground-fed springs up the Whitaker Slough in a whimsical place called Mermaid Cove. We developed a growing curiosity about how to regain access to this area, which has been blocked by large logs from boat access.
After a paddle up the Slough to investigate, the Council staff found that the logs were deeply embedded in the Slough's sediment; we started brainstorming who, how, what tools, safety, and the project's timing.
Leaning into our partnership with the Flood Safety District, we started the conversation with their operations and environmental team to seek guidance. Safety, effectiveness, environmental/habitat disturbances, and community access were at the forefront of our minds.

Needing to get eyes on the work ahead of us, both parties met on the water to scout the log blockage. Little did we know there was not just one blockage, but 3-4 more to be found upstream on the Whitaker Slough.
The Flood Safety District took action the very next day. The logs have been cleared, and the east is waiting to be paddled!
| | |
Both the Flood Safety District and CSWC are eager for all to access paddling east on the Whitaker Slough and to once again explore the magical Mermaid Cove.
Next time you’re paddling on Whitaker Slough, go east and explore. Maybe you’ll find a real-life mermaid, your favorite bird, or the enchanting ground-fed springs!
A thank-you to the Flood Safety District for their collaboration, labor, and feats, and a huge thank-you to Pamela Slaughter from POCO for sparking curiosity and sharing the stories of Mermaid Cove.
