| Notes | In November, 2012, PacifiCorp put in a fish ladder over Soda Springs Dam, which opened up new spawning habitat for anadromous salmonids on Fish Creek. The fish ladder was a relicensing requirement. In advance of this change, the author captured fourteen wild summer steelhead and relocated them into Fish Creek, on the blocked side of Soda Springs Dam, in order to study their movements and behavior in newly accessible habitat. From June, 2010 through late May, 2011, the trout were tracked using radio telemetry. “The main goal of this project was to provide management recommendations for habitat restoration projects upstream of the Soda Springs Dam and above a natural waterfall in the Fish Creek tributary on the North Umpqua River in Oregon.” (p.3) The author also used stable-isotope analysis to document historically salmon-derived nitrogen in the landscape from samples of Douglas fir trees. This study is an interesting first look at fish behavior in newly re-opened habitat. The major professor was David L. G. Noakes. |
