Soil Investigations for Data Collection in the Delta Initial Study/Proposed Mitigated Negative Declaration 211 Species Act (ESA) consultation on coordinated long-term CVP and SWP operations. This proposed project crosses multiple county lines, including, but not limited to, Sacramento, Solano, Yolo and San Joaquin counties. A Notice of Preparation (NOP) for an EIR was filed on August 19, 2019. Department of Water Resources- Temporary Barriers Project (TBP) The TBP refers to the annual installation, maintenance, and removal of up to four rock barriers in the channels of the southern portion of the Sacramento-San Joaquin Delta near the cities of Tracy and Lathrop in San Joaquin County, California. These barriers have been installed annually (with the exception of a few years) since 1991, and are designed to act as flow control structures, “trapping” tidal waters behind them following a high tide in order to improve water levels and circulation for local south Delta farmers. The TBP is anticipated to continue through water year 2022 and potentially further into the future. All of the barriers are typically installed during the period between March and November each year. Three of the barriers (one each at Old River near Tracy, Middle River and Grant Line Canal) facilitate pumping by agricultural water diversions for irrigation purposes. A fourth barrier, the Head of Old River barrier, blocks migratory movements through the Old River channel and directs juvenile and adult anadromous fish species migration through the San Joaquin River corridor. None of the barriers can be constructed when ambient flows in the San Joaquin River exceed 5,000 cubic feet per second (cfs) as measured at the Vernalis monitoring station, as high flows can displace the rock barriers and create extremely hazardous and unsafe working conditions. Department of Water Resources- Salmon Protection Tech Study The purpose of the proposed Salmon Protection Technology Study (SPTS) project would be to construct and operate barriers at Delta junctions with known lower survival salmonid migratory pathways, study other emerging salmonid barrier technologies and collect salmonid survival and behavioral data. Locations under consideration would include Georgiana Slough, Steamboat Slough, and Sutter Slough within Sacramento, Solano and/or San Joaquin counties. Work would be expected to occur for five years, annually, between 2020 and 2025. As a result of the 2009 NMFS BiOp, the SWP and CVP operations must comply with Reasonable and Prudent Alternative (RPA) Action IV.1.3 to reduce diversion of juvenile salmonids into the central and south Delta. Currently, the presence of endangered salmon species in the south Delta require significant SWP and CVP operations curtailments. The SPTS project would provide the best available science and engineering for the final implementation of Salmon Survival Engineering Solutions Phase III.
