|Objective 1. Determine the numerical status of existing natural populations and develop methods for monitoring that status. Determine if these populations belong to one or more gene conservation groups.
Determine if Sandy and Clackamas spring chinook belong to the same gene conservation group as spring chinook above Willamette Falls. Estimate the proportion of wild fish in the spawning populations.
Develop annual indexes for monitoring natural spawner abundance of spring chinook. Establish escapement goals for natural production in Willamette River sub-basins and in the Sandy River.
