The Delta Conveyance Project (DCP) involves a plan to build a canal or a tunnel to move water around the Sacramento Delta instead of through it more naturally. The Office of Historic Preservation of the Winnemem Wintu Tribe (Tribe) has been consulting for the past year with the California Department of Water Resources regarding the DCP and its potential effects on both water quality and the ecology of the Sacramento-San Joaquin Delta. Thus far, the Tribe’s consultation has led DWR to acknowledging that the entire Delta is a Traditional Cultural Resource and therefore the impacts to the whole system must be assessed when considering projects under the California Environmental Quality Act. The Tribe will use the funding to continue studying and engaging the Department of Water Resources on their concerns surrounding: (1) the water quality impacts of additional extraction of water for transport to Southern California, (2) the potential for saltwater intrusion, 3) the mortality of anadromous and endemic fish species that may be destroyed by transport pumps, and 4) potential introduction of nonnative fish species. The Tribe believes the Delta must be protected from further negative impacts to maintain and improve salmon populations while providing water to satisfy human needs in California’s future. Tribal representatives will engage in the public stakeholder process and advocate that adequate streamflow to the Delta and outflow is needed to improve water quality and reduce saltwater incursion. They will also press the State to include solutions to mitigate potential pump mortality of migrating salmonids and reduce predation on salmon by exotic predators. The funding will support the creation of a report which identifies additional Tribal Cultural Resources likely to be affected by the DCP as well as summarize water quality and ecosystem impacts of the current proposal.
