Deepwater Slough was restored through dike removal in the summer of 2000 to provide in-channel habitat and restore an important migratory corridor for juvenile Chinook and other salmon in the Skagit Delta. Dikes blocking the channel were removed from a site near the upstream end of the distributary channel and 1000m downstream from this location. Geomorphic changes quickly followed dike removal, particularly upstream of the upstream dike. Changes in planform geometry from 2000 to 2002 have been previously reported (Hood 2003). This report provides additional planform monitoring results for 2004 and comparisons of channel cross-section changes from 2000 to 2005. The monitoring results reported here are preliminary. The site will likely continue to evolve in coming years and increasingly resemble natural tidal marshes. The great unknown is, at what rate will change occur?
