  • New bar forming at head of Indian Creek side channel (constructed 2007)
  • First high flow since construction at the Sawmill (Lewiston) site
  • Hoadley Gulch Side Channel just after construction - this side channel was a popular spawning site in 2009 and 2010
  • New construction of bars and meanders at the Reading Creek restoration site (2010)
  • New bar formed at Lowden Ranch by injecting gravel into the river during the 2010 peak restoration flow release
  • Wood in side channel constructed prior year (2007) providing habitat for young salmon
  • 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
  • Habitat structure for young salmon at Sawmill (Lewiston), constructed in 2010
  • Newly constructed meanders at the Lowden Ranch restoration site (2010) - designed to increase channel complexity and encourage a variety of salmon habitats
  • Sven Olbertson Side Channel, constructed in 2008 - this has become a popular area for spawning
