A potentiometric surface map for spring 2016 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages. Most of the wells were measured annually or one time, after installation, but some wells were measured more than one time in a year and a small number of wells were measured continually. Streamgages were typically operated continuously. The potentiometric surface map for 2016 was created as part of the U.S. Geological Survey (USGS) Water Availability and Use Science Program to support investigations that characterize...

Data for static groundwater-levels measured in about 645 wells during the period of January-April 2016 by the United States Geological Survey (USGS), the Mojave Water Agency, and other local water districts were compiled to construct a regional water-table map. The downloadable shapefile shows the elevation of the water table in the Mojave River and Morongo groundwater basins. This dataset is a digital representation of the contours presented on Plate 1 of Regional Water Table (2016) in the Mojave River and Morongo Groundwater Basins, Southwestern Mojave Desert, California: U.S. Geological Survey Scientific Investigation Map, doi:10.5066/sim3391, published by Meghan C. Dick and Adam R. Kjos. It is a continuation...

Thirteen geospatial datasets were developed to characterize the shallow groundwater system in the Lower Gunnison River Basin, Colorado. These geospatial datasets provide information about regolith thickness and altitude of the bedrock surface underlying regolith and display, in vector and raster formats, the generalized extent and thickness of regolith sediments that comprise the shallow groundwater system in the Lower Gunnison River Basin; display, in raster and vector format, the generalized altitude and configuration of the bedrock surface that comprises the base of the shallow groundwater system in the Lower Gunnison River Basin; provide information about depth to water, altitude of the potentiometric surface,...

The depths to a high and average water table below the land surface were estimated across the Clover Creek watershed in Pierce County, Washington. Groundwater model simulations provided initial estimates of water-table depths for the analysis. To provide optimized, data-driven estimates of these depths, a continuous bias correction surface was applied to model output according to differences between simulated and observed water levels at observation wells.

This dataset consists of contours showing the generalized altitude of the potentiometric surface for the shallow groundwater system in the Lower Gunnison River Basin in Delta, Montrose, Ouray, and Gunnison Counties, Colorado. Potentiometric-surface altitude was contoured from values in the raster dataset potalt. The U.S. Geological Survey prepared this dataset in cooperation with the Colorado Water Conservation Board.

This point dataset contains water-level information concerning depth to water, potentiometric-surface altitude, and saturated thickness for the shallow groundwater system at selected well and borehole locations in the Lower Gunnison River Basin in Delta, Montrose, Ouray, and Gunnison Counties, Colorado. Depth-to-water data were compiled from measurements reported by the Colorado Division of Water Resources, U.S. Geological Survey, and Bureau of Reclamation. Potentiometric-surface altitude values were computed from the potentiometric-surface altitude raster dataset (potalt). Saturated-thickness values were computed from the saturated-thickness raster dataset (satthk). The U.S. Geological Survey prepared this dataset...
