<span style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'>Archived on 20161130 and the name was change from i08_B118_CA_GroundwaterBasins to i08_B118_CA_GWaterBasins20161130. The dataset is a feature class showing the boundaries of 515 groundwater basins and subbasins as defined by the California Department of Water Resources (Bulletin 118, 2003). The file is in ESRI geodatabase format and is intended for use with compatible GIS software. Groundwater basins are represented as polygon features and designated on the basis of geological and hydrological conditions - usually the occurrence of alluvial or unconsolidated deposits. When practical, large basins are also subdivided by political boundaries, as in the Central Valley. Basins are named and numbered per the convention of the Department of Water Resources. The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR GIS Spatial Data Standards. DWR makes no warranties or guarantees, either expressed or implied, as to the completeness, accuracy or correctness of the data, nor accepts or assumes any liability arising from or for any incorrect, incomplete or misleading subject data. The official DWR GIS Data Steward for this dataset is Brett Wyckoff, who may be contacted at 916-651-9283, or at brett.wyckoff@water.ca.gov. Comments, problems, improvements, updates, or suggestions should be forwarded to the official GIS Data Steward as available and appropriate.</span>

The total area of the model domain is 20,742 square miles. It contains 32,537 elements, which make up the model grid of the C2VSimFG. The boundary includes three hydrologic regions: Sacramento Region, San Joaquin River Region and the Tulare Lake Region, which have distinctively, different hydrologic and geologic settings. The model boundary is based on the Bulletin 118 - 2003 basin boundaries generalized for the model node spacing.</span><br /></p></div>

The elements are subdivided into 21 subregions. Each element is composed of corresponding groundwater nodes within the model domain. The model domain area is 20, 742 square miles, and the average element size is roughly 407 acres. The boundaries of the model grid were developed using a set of control points at important locations of the model area. The finite grid mesh was created using GIS and several Excel and FORTRAN utilities. The grid size was refined in areas of higher groundwater gradient and/or areas that are more critical from hydrogeological viewpoints. The grid lines are designed parallel to the streamflow direction, when possible, as well as the groundwater streamlines, to capture the surface and subsurface drainage patterns. Nine major faults in the Central Valley are represented by thin strip of elements of around 500 feet. The dataset excludes three geologic outcrops: Sutter Buttes, Kettleman Hills and Capay Valley Hills, which are areas not included in the Bulletin 118. The dataset is maintained by the Sustainable Groundwater Management Office, Modeling and Tools Support Section.</span><br /></p></div>

These features were added to the landslide deposits mapped in USGS Publication MF-1790, &quot;Geologic Map of the Late Cenozoic Deposits of the Sacramento Valley and Northern Sierran Foothills, California&quot; (Helley and Harwood,1985). This data set was created by scanning the five- original sheets from USGS Publication MF-1790 (Helley and Harwood, 1985), the five sheets were georeferenced individually and the geologic information was digitized using AutoCAD 2006. The accuracy of the digitized lines was deemed to be within acceptable error tolerances, with the digitized lines accurately matching the original drafted lines in USGS Publication MF-1790 (Helley and Harwood, 1985). In general, the width of the contact lines on the paper copy, accounting for scale, ranged up to about 20 meters (66 feet). During the original digitization, minor topological mistakes (such as identical rock units on both sides of a lithologic contact or unclosed polygons) and omissions (such as unidentified lithologic units) were applied according to the best available knowledge. Comparisons were made between the original mylar and colorized field sheets (as available), in addition to the Geologic Map of the Battle Creek Fault Zone, Northern Sacramento Valley, California (USGS Map MF-1298, 1981), the Geologic Map of the Chico Monocline and Northeastern Part of the Sacramento Valley, California (USGS Miscellaneous Investigations Series Map I-1238, 1981), and the Geologic Map of the Red Bluff 30' X 60' Quadrangle, California (USGS Geologic Investigation Series Map I-2542, 1995).

There are a total of 1,024 small watersheds along the northern, southern, western, and eastern boundaries of the Central Valley that covers 6,662 square miles. The dataset is a boundary condition of the model used to stimulate the time-dependent surface and subsurface flows from the small watersheds outside the Central Valley. The C2VSimFG uses the monthly surface water discharge, recharge, and subsurface groundwater flows data from the small watersheds to calculate the output water budgets.

Positive values indicate groundwater has risen (groundwater surface elevation has increased) from the early year to the late year, while negative values indicate groundwater level surface has fallen (decreased in elevation ) from the early year to the late year. For 'Elevation' type contours, contours represent lines of equal elevation of the estimated groundwater level surface above mean sea level.

The 2017 polygons are digitized from the 2017 Delta LiDAR imagery by the Division of Engineering, Geomatics Branch, Geospatial Data Support Section. The older pre-2017 polygons were all digitized by staff in the Delta Levees Program. Data can be queried for a single year or date range using the 'Year' field. Historical data was compiled and merged from datasets provided by the Delta Levees program. Data coverage differs between years. Absences or gaps in historical data may occur. Older acquisitions generally have a smaller footprint than recent imagery acquisitions. The 2017 in-channel islands cover the Legal Delta, and also include Chipps Island.</span>
