San Joaquin River Restoration Project
Historically, the San Joaquin River sustained the southernmost populations of spring-run, fall-run, and late-fall run Chinook Salmon Oncorhynchus tshawytscha in North America. However, the construction of Friant Dam and increased ground water pumping and water diversions in the San Joaquin Valley led to the loss of volitional fish passage, degradation of salmon spawning habitats, and the extirpation of all salmon runs in the upper San Joaquin River by the 1950's.
In 2006, a settlement was reached between National Resources Defense Council, Friant Water Users Authority, and the U.S. Departments of the Interior and Commerce to establish a restoration plan for the upper San Joaquin River below Friant Dam.
The settlement of this case led to the establishment of the San Joaquin River Restoration Program (SJRRP). The San Joaquin River Restoration Program (SJRRP) is a multi-agency collaboration whose two main goals are to:
1. Restore and maintain naturally reproducing and self-sustaining populations of salmon and other fishes in "good condition"to the San Joaquin River Restoration Area (SJRRA)- the mainstem of the San Joaquin River from Friant Dam to the Merced confluence; and
2. Avoid/reduce any adverse water supply impacts on the Friant Division long-term water contractors resulting from restoration flows in the SJRRA. The program spans multiple offices and agencies; including the U.S. Fish and Wildlife Service, U.S. Bureau of Reclamation, U.S. National Marine Fisheries Service, California Department of Water Resources, and the California Department of Fish and Game.
Here at the Lodi office, we conduct a number of monitoring projects to inform the SJRRP’s ongoing restoration projects. Currently, we are focused on evaluating and guiding the restoration of spring-run Chinook Salmon to the San Joaquin River Restoration Area.
