The project consists of constructing a permanent weir with a positive fish barrier and fish collection facility downstream of the existing Wallace Weir structure in the Knights Landing Ridge Cut (KLRC).The proposed project would also involve removal of the existing Wallace Weir, which is a seasonally-constructed, earthen berm that crosses the KLRC. Migrating adult salmon are currently able to enter the KLRC through the Wallace Weir when they are attracted by certain flow regimes. Once salmon enter the KLRC, there is no upstream route for them to return to the Sacramento River; the fish are unable to spawn and perish without reproducing. This project would address that problem while maintaining Wallace Weir's ability to supply water to adjacent agricultural fields.
