Photo Database Series Monitoring: Monitoring Sites in Corte Madera Creek 1999
Habitat typing site CM-01 was located at the U.S. Army Corps of Engineers concrete flood control channel in Kentfield. This area is under tidal influence and serves as a migration corridor for steelhead trout. However, due to the absence of structure and protective cover, as well as a poorly functioning fish ladder upstream, emigrating steelhead may be prone to predation by birds (Rich, 2000). Photo taken by A.A. Rich and Associates in 1999.
Temperature monitoring was conducted at the beginning of the concrete channel seen in the previous picture by A. A. Rich and Associates using a thermograph during April through September 1999. The temperature site number was CMC-1b. Photo taken in 1999 by A.A. Rich and Associates.
