Burow, Karen Jurgens, Bryant Johnson, Tyler 2003 1.0 Water Resources Investigations Report WRIR 03-4166 Sacramento, CA U.S. Geological Survey http://water.usgs.gov/pubs/wri/wri034166/ Ten hydrogeologic provinces of California are represented by a region- class feature called "provinces" within this digital data set. These provinces were identified and defined in the USGS Water Resource Investigation Report (WRIR) 03-4166 (Belitz and others, 2003) titled, "Framework for a Ground-water Quality Monitoring and Assessment Plan for California". Hydrogeologic provinces are generalized areas where hydrology and/or geology have similar characteristics. The Southern Cal Islands group was not previously defined as a province in WRIR 03-4166, and is therefore identified as a group in this dataset. These provinces were created by grouping polygons from two formally created digital data sets into respective provinces. New polygons were created where necessary. The two digital data set sources consisted of watershed polygons (calwater) and groundwater basin polygons (gw_basins) compiled to create an original publication of hydrogeologic province boundaries in the form of a region-class within the data set. By symbolizing on the region- class, the user can view the ten hydrogeologic provinces and one grouped province in their simplest representation, without watershed and ground- water basin boundaries obscuring the province areas. Original polygons for both the watershed data set and the ground-water basin data set were retained as much as possible. This digital data set was created to provide a context for developing a statewide, comprehensive ground-water monitoring and assessment program as per the requirements of the California State Assembly bill AB599. The development of this data set facilitated analysis and identification of the priority basins and areas outside basins. This data set was developed from previously developed digital data sets of ground-water basins (California Department of Water Resources, 2002) and watersheds (California Department of Forestry and Fire Protection, 1999). The "Source Information" section contains further descriptions. The previously developed digital maps were used to maintain consistency with boundaries recognized by State agencies. Hydrogeologic provinces identify regions of similar geologic or hydrologic properties. The "Process Step" section contains a detailed description of each province or group. Most of the attributes were retained from the two coverages (calwater) and (gw_basins). The "Attributes" section provides more information on attribute descriptions. A further description of the hydrogeologic provinces and their descriptions can be found in the USGS Water Resource Investigation Report WRIR 03-4166 http://water.usgs.gov/pubs/wri/wri034166/. Some parts of this metadata were extracted from Appendix B of the same report.

Introduction: This digital data set was created to provide a context for developing a statewide, comprehensive ground-water monitoring and assessment program as per the requirements of the California State Assembly bill AB599. The metadata contained herein contains excerpts from Appendix B of the USGS Water Resource Investigation Report WRIR - 03-4166 http://water.usgs.gov/pubs/wri/wri034166/. This data set was developed from previously developed digital data sets of ground-water basins (California Department of Water Resources, 2002) and watersheds (California Department of Forestry and Fire Protection, 1999). The development of this data set facilitated analysis and identification of the priority basins and areas outside basins. The previously developed digital maps were used to maintain consistency with boundaries recognized by State agencies. Ten hydrogeologic provinces and one grouped province were created and are represented by a region-class feature called "provinces" within the digital data set. By symbolizing on the region-class, the user can view the ten hydrogeologic and one grouped province in their simplest representation, without watershed and basin boundaries obscuring the province arcs. The boundaries between hydrogeologic provinces generally correspond with the boundaries between major geomorphic and geologic provinces (Norris and Webb, 1990; Saucedo and others, 2000; California Geological Survey, 2002). However, the specific locations are based on ground-water basin polygons (California Department of Water Resources, 2002) and on watershed polygons (California Department of Forestry and Fire Protection, 1999). In areas where ground-water basin polygons approximate province boundaries, ground-water basin polygons were used; therefore, ground- water basins are always contained within a single province. In other areas, the watershed polygons that most closely approximated the province boundaries were used. In a few instances, the boundary between hydrogeologic provinces is not approximated by either a ground-water basin or watershed polygons. In those instances, watersheds polygons were divided manually between hydrogeologic provinces. No ground-water polygons were divided. A summary of the grouping process appears below, highlighting the areas where polygons were altered. Process: 1) Downloaded the groundwater basin shapefile draft version 2 from the DWR website. 2) Reprojected and converted shapefile to coverage. 3) Created redefined items REGION and BASIN from the "DWR_" column 4) Added items SUBBASIN and GW_ID. 5) Populated SUBBASIN by selecting basins that used a .%% in the "SUBBSN_" field and then selected the right three digits. (% is a wild card) 6) Populated the GW_ID item by copying over the "DWR_" item and then selecting those basins in REGION 5 BASIN 21 and 22 and copied over the SUBBASIN (.xx) number into the GW_ID. This was done to break up the San Joaquin and Sacramento Basins into smaller subbasins. 7) One polygon within the basin "Conejo-Tierra Rejada Volcanic" had a misnamed polygon. It was labeled "Conejo-Tierra Rejada Volcanics" instead of "Conejo-Tierra Rejada Volcanic". The "s" was subsequently dropped. (basin 4-21) 8) Downloaded CALWATER shapefile from Forestry website. 9) Reprojected and converted shapefile to coverage. 10) Used the ERASE command to remove the CALWATER polygons that fell within a groundwater basin. This created a new coverage that only has CALWATER polygons outside of areas considered a groundwater basin. 11) Used the UNION command to merge together the newly created "erase" coverage in step 10 with the GW_BASINS coverage created in steps 1-7. 12) Deleted 16 dangling nodes and built coverage. Clean was not used. 13) Grouped each polygon from the resulting coverage created in step 12 into hydrogeologic provinces. The grouping is outlined below for each province: (Excerpt from Appendix B, WRIR 03-4166) The Northern Coast Ranges hydrogeologic province includes 79 ground-water basins and 126 watersheds. The boundary with the Klamath Mountain province is primarily defined by watersheds that approximate the Coast Range Fault; one watershed (Klamath Glen hydrologic subarea) extends to both sides of the fault and was divided between the two provinces. Two other watersheds (Platina and Ono hydrologic subareas) were also divided between the two provinces to better approximate the contact between Cretaceous sedimentary rocks of the Coast Ranges from the Paleozoic and Mesozoic metamorphic rocks of the Klamath Mountains. The boundary between the Northern Coast Ranges and Central Valley provinces is defined by the boundary of the Sacramento ground-water basin. The Southern Coast Ranges hydrogeologic province includes 74 ground-water basins and 89 watersheds. The western part of the boundary with the Transverse and selected Peninsular Ranges province is defined by ground-water basin boundaries that approximate the Santa Ynez Fault; the eastern part of the boundary is defined by watershed boundaries that approximate the Santa Ynez and Big Pine Faults. The boundary with the Central Valley province is defined by the boundary of the San Joaquin ground-water basin. The Klamath Mountains hydrogeologic province includes 7 ground-water basins and 51 watersheds. The boundary with the Northern Coast Ranges province is defined by watershed boundaries that approximate geologic boundaries; three watersheds (Klamath Glen, Platina, and Ono hydrologic subareas) are divided between the two provinces. The boundary with the Modoc Plateau and Cascades province is defined by ground-water basin and watershed boundaries that approximate geologic boundaries; three watersheds (Hornbrook, Squaw Valley, and Big Bend hydrologic subareas) are divided between the two provinces. The boundary with the Central Valley province is defined by the boundary of the Sacramento ground-water basin. The Modoc Plateau and Cascades hydrogeologic province includes 55 ground- water basins and 70 watersheds. The boundary with the Klamath Mountains province is defined by ground-water basin and watershed boundaries that approximate geologic boundaries; three watersheds (Hornbrook, Squaw Valley, and Big Bend hydrologic subareas) are divided between the two provinces. The boundary with the Sierra Nevada province is also defined by ground-water basin and watershed boundaries that approximate geologic boundaries; three watersheds (Upper Little Chico hydrologic area, West Branch North Folk hydrologic area, and Butt Valley hydrologic subarea) were divided between the two provinces. The boundary with the Central Valley province is defined by the boundary of the Sacramento ground-water basin. The Central Valley hydrogeologic province consists of the Sacramento and San Joaquin ground-water basins, and includes eight watersheds. These two ground-water basins include 36 relatively large ground-water subbasins, which for the purposes of this study are recognized as individual ground- water basins. The boundaries of the Central Valley hydrogeologic province are entirely defined by ground-water basin boundaries. The province includes a few areas of relatively low permeability areas that are surrounded by ground-water subbasins. The Sierra Nevada hydrogeologic province includes 22 ground-water basins and 161 watersheds. The boundary with the Central Valley Province is defined by the boundaries of the Sacramento and San Joaquin ground-water basins. The boundary with the Modoc Plateau and Cascades province is defined by ground-water basin and watershed boundaries that approximate geologic boundaries; three watersheds (Upper Little Chico hydrologic area, West Branch North Folk hydrologic area, and Butt Valley hydrologic subarea) were divided between the two provinces. The boundary with the Basin and Range province is also defined by ground-water basin and watershed boundaries that approximate geologic boundaries; one watershed (Upper Owens hydrologic area) was divided between the two provinces. An additional watershed (Neenach hydrologic area) was divided between the Sierra Nevada province and Transverse and Selected Peninsular Ranges province. The Basin and Range hydrogeologic province includes 45 ground-water basins and 56 watersheds. The boundary with the Sierra Nevada province is defined by ground-water basin and watershed boundaries that approximate geologic boundaries; only one watershed (Upper Owens hydrologic area) was divided between the two provinces. Most of the boundary with the Desert province is defined by ground-water basin boundaries that approximate the Garlock Fault. The easternmost part of the boundary is defined by ground-water basin boundaries that approximate the geomorphic boundary between the north-south trending mountains of the Basin and Range province and the broader, more widely-spaced mountains of the Desert province. The Transverse and selected Peninsular Ranges hydrogeologic province includes 33 ground-water basins and 167 watersheds. The boundaries with the Southern Coast Range, Sierra Nevada, and Desert provinces are defined by ground-water basin and watershed boundaries that approximate geologic boundaries, including the Santa Ynez, Big Pine, and San Andreas Faults. Mountain areas along the boundaries, other than the Sierra Nevadas, are generally included in the Transverse and selected Peninsular Ranges province. Only one watershed (Neenach hydrologic area) was divided between provinces. The boundary with the San Diego Drainages province is defined by boundaries between relatively large watersheds defined as "hydrologic units" (California Department of Forestry and Fire Protection, 1999). The boundaries between the large-scale watersheds (hydrologic units) also correspond to the boundaries between ground-water basins, including the Santa Ana, Elsinore, and San Jacinto ground-water basins, which are included in the Transverse and selected Peninsular Ranges province. The San Diego Drainages province includes 25 ground-water basins and 163 watersheds. The boundary with the Transverse and Selected Peninsular Ranges to the north is defined by the boundaries of hydrologic units, which are relatively large watersheds. The boundary with the Desert province to the east is defined by the boundaries of hydrologic regions, which are the largest scale watershed identified by the State Water Resources Control Board (California Department of Forestry and Fire Protection, 1999). No watersheds, including relatively small-scale hydrologic subareas, were divided along any of the boundaries of the San Diego Drainages province. The Desert hydrogeologic province includes 96 ground-water basins and 110 watersheds. The boundary with the Transverse and Selected Peninsular Ranges province is primarily defined by ground-water basin boundaries that delineate the San Gabriel and San Bernardino Mountains, which are part of the Transverse and Selected Peninsular Ranges province, from ground-water basins that are a part of the Desert province. Ground-water basins along the boundary include the Antelope, Mojave, and Coachella basins. The boundary with the Basin and Range province is defined by ground-water basin boundaries, as noted previously. The boundary with the San Diego Province is defined by a major watershed divide demarcating the South Coastal and Colorado River hydrologic regions. Southern Cal Islands: WRIR 03-4166 (Belitz and Others, 2003) did not identify the Southern California Islands as part of any province. These islands do not contain any identified ground-water basins or watershed polygons. They have been grouped in this dataset to facilitate complete graphic representation for the entire State. 00002002 Tyler Johnson U.S. Geological Survey Geographer mailing address
