The Project includes executing Warren Act contract(s) with the United States Bureau of Reclamation (USBR) and State Water Project Analysis Office (SWPAO) Agreement(s) with the Department of Water Resources to convey up to 30,000 acre-feet of groundwater in the San Luis Canal (SLC) through February 2023, provided the allocation to south of Delta Central Valley Project water contractors is 20% or less, or until the Governor’s State of Emergency Proclamation is lifted. The Project would allow well owners within the District that are more than 2 miles from the SLC to pump groundwater into the SLC, using existing or temporary surface pipelines and existing integration locations along the SLC, for delivery and use on other land in the District, or to temporarily store it in San Luis Reservoir to meet peak summer crop demands and guard against water shortages in 2022. Per USBR’s Water Quality Monitoring Plan (usbr.gov/mp/nepa/includes/documentShow.php?Doc_ID=46945; see Appendix B) for the Project, water quality testing and groundwater level monitoring will be performed routinely.
The District’s implementation of the Project is in response to emergency conditions, which are demonstrated by, among other factors, the limited amount of water available from the Central Valley Project. The District anticipates the USBR will rely upon its recent approval of the Five-Year Warren Act for Westlands Water District Environmental Assessment and Finding of No Significant Impact (CGB-EA-2020-032 and CGB-FONSI-2020-032, respectively) to support execution of the one-year Warren Act contract.
