For the third consecutive year the major breeding grounds of the Canada 
goose on the Lower Snake and Columbia River systems of southcentral Washington

has been designated by units based upon its eventual permanent alteration behind 
a system of power dams. Unit Iis that part of the Columbia River from below 
Priest Rapids to the town of Richland. This area lies entirely within the Hanford
