By Oct. 20, a day after the Marmot Dam site was breached by rising river flows, fish could already move upriver free of obstructions. In just three days coho salmon were migrating past the site.
Meanwhile, PGE continues to monitor the movement of sediment in the river to ensure continued fish passage, most notably for the winter steelhead to follow in March. Water quality and critical side-channel habitat are also being monitored.
Broodstock collection complete
Collection of native fall Chinook broodstock from their spawning grounds in the Lower Sandy River was completed in November. The work was conducted in partnership with the Oregon Department of Fish and Wildlife.
The collected broodstock will be spawned in the hatchery, their offspring released into the Lower Sandy in spring 2008. (continued)
