As the Clackamas River flows in to the reservoir above our North Fork hydroelectric plant, the water slows and creates inviting conditions for salmon to spawn and juvenile fish to grow. But there was a problem: There wasn’t enough cool, shady habitat in this transitional area for the young fish to hide from predators and grow to adulthood.
The solution? Give Mother Nature a hand. We teamed up with the U.S. Forest Service, Clackamas River Basin Council and other partners to help.
Strategically placed logs invite fish to move in
The project involved designing and constructing wood habitat structures using nearly 600 logs along a 4,100-foot reach of the Clackamas River. The completed arrangements, which look like natural log jams, create cool, shady “fish nurseries.”
We also removed invasive plants, such as blackberries, Scotch broom and reed canary grass, to allow native plants to grow and shade the river.
The project was immediately successful, with schools of juvenile and adult Chinook salmon, coho salmon and steelhead — along with Pacific lamprey, crayfish and birds — using the structures as shelter and resting spots.
This project is just one of many ways we work to power your day sustainably, protecting rivers, fish and wildlife habitat in areas where we operate generating plants.
