Summary
[edit]DescriptionBird's eye view of the fish-tagging operation (8595559077).jpg | Ecologists for the U.S. Army Corps of Engineers Sacramento District begin tagging 50 steelhead trout and 200 late-fall Chinook salmon smelt at the Coleman National Fish Hatchery in Anderson, Calif. on March 25, 2013. The fish-behavior data obtained over a 75-mile stretch of the Sacramento River will help researchers better evaluate habitat restoration work under the Sacramento River Bank Protection Project, a joint flood risk reduction effort between the district and the state's California Central Valley Flood Protection Board to repair riverbank erosion along the Sacramento River and its tributaries.
