San Lorenzo Valley Water District
Fall Creek Fish Ladder Project
NOE - Notice of Exemption
Proposed project activities include improvements to the existing fish ladder through modifying the four existing concrete weirs; constructing two additional concrete weirs downstream of the existing weirs to meet new design profile (12-inch vertical drops); and placing concrete grade control weir upstream of intake screen. These actions would reduce average drop height and concentrate flow toward the center of the channel and promote plunging flow into the pool and help maintain sediment transport through the pool.
The proposed project would not result in expansion of use. Project implementation would improve fish passage conditions of the fish ladder to be consistent with the fish passage variance issued by National Marine Fisheries Service (NMFS) and California Department of Fish and Wildlife (CDFW) (dated April 19, 2019). Proposed activities would not alter the amount of water intake being diverted to the town of Felton.
