The U.S. Army Corps of Engineers and the Columbia River Inter-Tribal Fish Commission invite the public to Lampreypalooza – an afternoon of science, storytelling, and up-close encounters with one of the Northwest’s most ancient native fish.

Returning to Bonneville Dam on July 9, Lampreypalooza is a free, family-friendly event that highlights the cultural importance of Pacific lamprey and the efforts to support their recovery. Visitors can explore live demonstrations, hear from Tribal representatives, and see lamprey up close.

All events are open to the public and take place at Bonneville Dam.

Why lamprey?
Pacific lamprey are a key species in the Columbia River Basin. They’re culturally significant to Tribal Nations, play an important role in the food web, and have survived hundreds of millions of years of environmental change. Lampreypalooza shines a light on these ancient fish, and the partnerships working to protect them.
