Carson Jeffres Researcher for the Center for Watershed Sciences holds two salmon at Knaggs Ranch in the Yolo Bypass near Woodland on Wednesday, April 3, 2013. Salmon planted in the bypass six weeks ago were the size of the small fish, while the large fish is typical of their size today. Salmon planted in the Yolo Bypass about six weeks ago are being returned to the Sacramento River. And they're a lot fatter than they would have been otherwise, thanks to the vast banquet of insects and other food available in the bypass.
