  • Wood in side channel constructed prior year (2007) providing habitat for young salmon
  • New bar forming at head of Indian Creek side channel (constructed 2007)
  • Newly constructed meanders at the Lowden Ranch restoration site (2010) - designed to increase channel complexity and encourage a variety of salmon habitats
  • Hoadley Gulch Side Channel just after construction - this side channel was a popular spawning site in 2009 and 2010
  • Restoration high flow, spring 2010 - these high flows are designed to help the river restore itself
including reforming banks created by dredge mining and fixed in place by vegetation that grew when
the dam releases remained low year round
  • Sven Olbertson Side Channel, constructed in 2008 - this has become a popular area for spawning
  • New bar formed at Lowden Ranch by injecting gravel into the river during the 2010 peak restoration flow release
  • First high flow since construction at the Sawmill (Lewiston) site
  • Habitat structure for young salmon at Sawmill (Lewiston), constructed in 2010
