Specifically, the identification of the groundwater basins was initially based on the presence and areal extent of unconsolidated alluvial soils identified on 1:250,000 scale geologic maps provided by the California Department of Conservation, Division of Mines and Geology. The identified groundwater basin areas were then further evaluated through review of relevant geologic and hydrogeologic reports, well completion reports, court-determined adjudicated basin boundaries, and contact with local agencies to refine the basin boundaries. The 6.2 version of DWR’s Bulletin 118 dataset is available at: https://data.cnra.ca.gov/dataset/ca-bulletin-118-groundwater-basins1. The current dataset was updated at the time the latest Bulletin 118 document was produced, and is based on geological maps and other information available at that time. There have been minor corrections to the dataset since that time, as described in the data lineage.

Minor changes are occasionally made and will be documented in the metadata. Substantial changes, such as the extent of a basin boundary, must be completed as part of a public process, where the changes are proposed and public review and comment are welcomed before any changes are finalized. README_GSP Alternatives The Sustainable Groundwater Management Act (SGMA) established a process for local agencies to develop an Alternative in lieu of a Groundwater Sustainability Plan (GSP) (see Water Code §10733.6) for evaluation by DWR. An Alternative is required to be submitted to DWR for review no later than January 1, 2017, and every 5 years thereafter. GSP alternatives encompass entire groundwater basins so a separate feature class was not created. To extract the basins where alternatives were submitted, use the most recent feature class of Groundwater Basin boundaries from the DWR production atlas i08_B118_CA_GroundwaterBasins. Join the table GSP_Alternatives.xlsx to the groundwater basins feature class using the Basin_Subbasin _Number field in both the feature class and the table. Note: A geodatabase feature class table can be created from the Excel table and used for the Join. 1 -124.460304 -113.601215 42.019077 32.428022 No contradictions currently appear. Dataset appears to have all features. Due to the nature of the subject matter, edge to edge coverage of California does not exist. Of 515 Features: All have Basin_Number, Basin_Subbasin_Number, Basin_Name, Basin_Subbasin_Name, and Region_Office populated. Date_Record_Last_Edited, Record_Edited_By and Comments have some <null> values present by design. Locational Quality: Pursuant to Water Code 10722 and 23 California Code of Regulations 340.4 “a basin’s boundaries shall be as identified in Bulletin 118.” This report is not being made by a licensed land surveyor, and is not analogous to a positional accuracy statement as stipulated in the California Public Resources Code.14.2. Metadata Update - December 09, 2010 B118_v3_BasinBoundaries_NAD83_unprojected file was developed from B118v3NAD27UTM10 (dated 15-September-2006) which had a UTM 10 NAD 27 projection. The new file projection is defined as Latitude/Longitude NAD 83 and was converted using ESRI's Project tool in a two step process. Set one changed the Datum from NAD27 to NAD 83. The second step was to re-project the file from Universal Transverse Mercator 10 to Lat/Long Geographic projection for the use of CASGEM. 2010-12-09 Brett Wyckoff (916) 651-9283 901 P Street, Room 213B Sacramento CA 95814 brett.wyckoff@water.ca.gov Metadata Update – June 20, 2012 The shapefile B118_BasinBoundaries_v4_1.shp replaces B118_v3_BasinBoundaries_NAD83_unprojected.shp. Changes in the update include restoration of the northern portion of the North Yuba subbasin which was inadvertently removed during the 2003 B-118 Update. Also, the DWR District field (DWR_DIST) in the feature attribute table has been replaced by Regional Office Field (Regional_O). Basin boundary features in previous versions that were comprised of multiple polygons are now represented by single multi-part polygons. 2014-06-20 Brett Wyckoff (916) 651-9283 901 P Street, Room 213B Sacramento CA 95814 Brett.Wyckoff@water.ca.gov In an effort to realign locations of groundwater basins and subbasins, a process was set up to review the boundaries of all groundwater basins and subbasins to ensure they were aligned with the most current geologic boundaries. This process step was undertaken to review and correct some of the errors related to geologic boundaries. We reviewed each basin written description to provide a list of which basin boundaries referred to a geologic boundary and subsequently needed to have their geologic boundary portions reviewed. Once we had a list of the basins that needed review, we reviewed them with the using the California Geologic Survey maps of 1:250,000 scale (Regional Geoloci Map Series and The Geologic Atlas of California), and when readily available at other larger scale (more detailed) published geologic maps to ensure accurate coincidence of boundaries. For this review, High and Medium Priority basins with discrepancies between the linework and written description were sorted as having “significant”, “major”, or “minor” geologic issues. DWR has made adjustments to basin boundaries having a significant geologic issue, and an unambiguous written description. These realignments are not an adjustment to the written text contained within the Bulletin 118 but an attempt to better capture geographically the written descriptions. 2015-01-01 Erin Smith DWR 530-529-7314 2440 Main Street Red Bluff California 96080 Erin.Smith@water.ca.gov In an effort to realign locations of groundwater basins and subbasins, a process was set up to review the boundaries of all groundwater basins and subbasins to ensure they were aligned with the most current county boundaries. In the initial creation of the B118 dataset, there were some errors introduced with the use of county lines. This process step was undertaken to correct these errors. We reviewed each basin written description to provide a list of which basin boundaries needed to have their county line portions reviewed. Once we had a list of the basins that needed review, we reviewed them with the using the CalFire Counties dataset to ensure accurate coincidence of boundaries. These realignments are not an adjustment to the written text contained within the Bulletin 118 but an attempt to better capture geographically the written descriptions. 2015-06-01 Siran Erysian DWR 559-230-3312 3374 E. Shields Ave, Rm. A-1 Fresno CA 93726 Siran.Erysian@water.ca.gov In an effort to realign locations of groundwater basins and subbasins, a process was set up to review the boundaries of all groundwater basins and subbasins to ensure they were aligned with the most current stream boundaries. In the initial creation of the B118 dataset, there were some errors introduced with the use of stream and rivers as a boundary. This process step was undertaken to correct these errors. We reviewed each basin written description to provide a list of which basin boundaries referred to a stream or river and subsequently needed to have their county line portions reviewed. Once we had a list of the basins that needed review, we reviewed them using the National Hydrography Dataset’s Hydroline dataset to ensure accurate coincidence of boundaries. These realignments are not an adjustment to the written text contained within the Bulletin 118 but an attempt to better capture geographically the written descriptions. 2015-07-01 Siran Erysian DWR 559-230-3312 3374 E. Shields Ave, Rm. A-1 Fresno CA 93726 Siran.Erysian@water.ca.gov Following the adoption of DWR’s Basin Boundary Emergency Regulations, DWR provided an online Basin Boundary Assessment Tool (BBAT) to inform local agencies and the public about the existing Bulletin 118 groundwater basins and other relevant geologic and geographic data. DWR developed a Basin Boundary Modification Request System to enable local agencies to submit their requests for basin boundary modifications online, and the public to view those requests and provide comments. The draft approved basin boundary modifications were developed through DWR’s technical review of basin boundary modification requests and public comment made during the submission period, January 1, 2016 through March 31, 2016.DWR held a series of public meetings to present the Draft Approved Basin Boundary Modifications, provide an overview of the BBMRS and technical review process, answer clarifying questions and receive further public comments on the Draft Approved Basin Boundary Modification submissions. After the public meetings, the public comments were summarized and presented to the California Water Commission. Following consideration and potential incorporation of comments heard, DWR will publish the final basin boundary modifications. These basin boundary modifications were incorporated into the dataset. 2016-09-01 Tim Godwin DWR 916-651-9223 901 P Street Sacramento CA 95814 Timothy.Godwin@water.ca.gov The following edits and corrections were completed for this version (5.1): (A) Several minor typos and boundary errors were corrected by DWR, including: (1) two small erroneous polygons attributed to Santa Clara Valley East Bay Plain were removed, (2) spelling out previously abbreviated FM to FORMATION in Annapolis Ohlson Ranch Formation Highlands (3) fixed typo in Coastal Plain of Los Angeles Hollywood basin number, (4) modified the boundary of the San Joaquin Valley Westside and San Joaquin Valley Kings basins on the north and eastern edges, (5) modified the boundary of San Joaquin Valley Tulare Lake and San Joaquin Valley Tule basins east/west border, (6) modified boundary of San Joaquin Valley Merced and San Joaquin Valley Chowchilla basins, (7) modified boundary of San Joaquin Valley Merced and San Joaquin Valley Delta Mendota basins, (8) modified boundary of West Santa Cruz Terrace and Santa Cruz Mid County basins, (9) modified boundary of San Joaquin Valley Delta Mendota and San Joaquin Valley Chowchilla basins, (10) modified boundary of Kaweah and Tule basins.
