The proposed project consists of constructing a positive fish barrier on the downstream side of the Knights Landing Outfall Gates (KLOG) and repairing an erosion site on the right bank of the Colusa Basin Drain (CBD). The fish barrier would prevent adult salmonids from passing upstream through the KLOG, where they are subsequently lost from production. The barrier would consist of concrete wingwalls and metal picket weirs that would allow flows from the CBD to continue downstream. Erosion site repair would require placement of riprap along 100 linear feet of the right bank of the Colusa Basin Drain, which is a Sacramento River Flood Control Project levee.
