Basin Boundary Modification

The Sustainable Groundwater Management Act (SGMA) was signed by Governor Brown in September 2014 and the new laws became effective January 1, 2015.  SGMA established a process for local agencies to request that the California Department of Water Resources (DWR) revise boundaries of existing, DWR Bulletin 118 defined groundwater basins.  DWR developed the Basin Boundary Emergency Regulation through an extensive stakeholder outreach process and the State Water Resources Control Board (SWRCB) adopted the regulation on October 21, 2015.

Additional information regarding the Basin Boundary Modification Process is available on DWR’s Basin Boundary Modifications webpage at:

23 CCR §340.4 States that a “clear and unambiguous written description of a basin or subbasin boundary in Bulletin 118 shall prevail over any inconsistent basin or subbasin boundary as depicted on a map, in an electronic data file, or otherwise, except when modified pursuant to these regulations.”  The Mojave Water Agency (MWA), in cooperation with our partners Hi-Desert Water District (HDWD) and Joshua Basin Water District (JBWD), has proposed a science-based boundary modification for Warren Valley Groundwater Basin 7-12 (Warren Valley Basin) as designated by DWR’s Bulletin 118, Update 2003. The purpose of this proposed Basin Boundary Modification Request for the Warren Valley Basin is to bring the eastern basin boundary into alignment with the written description of the Warren Valley Basin provided in Bulletin 118, Update 2003.  The location of the eastern boundary of Warren Valley Basin in the Final 2016 Bulletin 118 Groundwater Basin Boundaries shapefile is inconsistent with the “Yucca barrier” of Lewis (1972), USGS Open-File Report 72-234 (https://pubs.er.usgs.gov/publication/ofr72234), as shown in the figure.  This proposed boundary modification request is an administrative adjustment to bring the graphically drawn basin boundary into alignment with the written description of the Warren Valley Basin provided in DWR’s Bulletin 118, Update 2003, as required by 23 CCR §340.4.
