Shortly after the construction of the Hansen Creek floodplain restoration project in 2010-2011, we conducted a pilot study of the initial use of the site by juvenile salmonids and the early development of invertebrate communities. We found that juvenile Coho salmon collected from the restored floodplain during periodic inundation events had higher instantaneous rations (a measure of feeding intensity) than Coho collected during regular monthly sampling in the creek channels. The floodplain site also had consistently higher insect abundances. Applying the data and lessons learned from the pilot study, we undertook a more comprehensive 13-month study of Hansen creek and …
