Data release of hydrogeologic data of the Yucaipa groundwater subbasin, San Bernardino and Riverside Counties, California
This data release contains digital data generated by the U.S. Geological Survey under cooperative agreements with San Bernardino Valley Municipal Water District to characterize the three-dimensional hydrogeology of the Yucaipa groundwater subbasin, located east of Los Angeles in southern California. This dataset contains borehole lithologic data, and geospatial data of a three-dimensional hydrogeologic framework model (HFM).The borehole dataset is released as a series of .csv ascii files including (1) individual borehole location, and (2) downhole lithologic interval data derived from well drillers' lithology logs and parsed to a series of textural descriptors. The geospatial data include polygon and polyline feature classes that are a 2-dimensional representations of the HFM. The polygon feature class is a cellular array where each model cell has multiple attributes including XY location, and interpolated elevations and thicknesses of the hydrogeologic units. The polyline feature class is a series of lines that represent the extent and location of faults included in the HFM. Sources of geologic and hydrogeologic data can be found in the metadata.
