Salmon habitat, Restoring salmon habitat


Crystal Springs is a small tributary of Tenmile Creek located in the lower drainage basin of the Nooksack River (Figure 1). It is 2.6 km in length and has a total relief of approximately 21 meters. A soil survey of the area suggests that prior to agricultural development, Crystal Springs existed as a swamp and was later trained into the man-made irrigation ditch which it currently occupies. Aerial photographs taken as early as June 30, 1947 reveal that the channel has undergone no significant change in morphology in the last 50 years. Recently a local landowner granted permission for the lower 250 meters of Crystal Springs to be restored for salmon habitat by the Nooksack Salmon Enhancement Association (NSEA). The purpose of this study was to design a plan for channel modifications necessary for creating salmon habitat along this lower reach and to establish baseline data to record changes in channel morphology following development of the site. A record of the channel changes will aid in evaluating project success and in developing effective plans for restoring other streams.
