The High Plains aquifer extends from approximately 32 to 44 degrees north latitude and 96 degrees 30 minutes to 106 degrees west longitude. The aquifer underlies about 175,000 square miles in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital dataset consists of a raster of water-level changes for the High Plains aquifer, predevelopment (about 1950) to 2019. It was created using water-level measurements from 2,741 wells measured in both the predevelopment period (about 1950) and in 2019, the latest available static water level measured in 2015 to 2018 from 71 wells in New Mexico and using other published information on water-level change in areas with few water-level...

F04_hpwlc1719t_Raster dataset of mapped water-level changes in the High Plains aquifer, 2017 to 2019
The High Plains aquifer extends from approximately 32 to 44 degrees north latitude and 96 degrees 30 minutes to 106 degrees west longitude. The aquifer underlies about 175,000 square miles in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This dataset consists of a raster of estimated water-level changes for the High Plains aquifer from pre-irrigation season 2017 to pre-irrigation season 2019. This digital dataset was created using water-level measurements from 7,195 wells measured in both 2017 and 2019. The map was reviewed for consistency with the relevant data at a scale of 1:1,000,000. Negative raster-cell values correspond to decline in water level and positive...
This raster dataset represents groundwater-level change from 1970 to 2020 in Smith Valley and Mason Valley, Nevada, calculated using approach 2. For this approach, depth-to-water measurements from 53 monitoring wells, represented as point values, were differenced between 1970 and 2020. Point values of change were interpolated into a raster to calculate valley-wide groundwater-level change. Depth-to-water was measured at the same 53 wells in 1995, 2006, and 2020. Depth-to-water measurements for 1970 were calculated by interpolating groundwater-level contours and extracting point values at the monitoring well locations. Groundwater-level change was estimated using two methods (approach 1 and 2) to address groundwater-level...

The High Plains aquifer extends from about 32 degrees to almost 44 degrees north latitude and from about 96 degrees 30 minutes to 106 degrees west longitude. The aquifer underlies about 175,000 square miles in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital data set consists of three sets of water-level measurements. The first set are the supplemental water-level measurements for 457 wells screened in the High Plains aquifer, not located in New Mexico , and measured in predevelopment, and between 2013 and 2016, but not in 2017. These supplemental measurements were used to calculate historical water-level change values for predevelopment to 2013 to 2016 and...

This USGS data release consists of 15 geospatial datasets for Smith Valley and Mason Valley, west-central Nevada, including contours representing groundwater levels based on depth-to-water measurements, groundwater-level change rasters calculated from groundwater-level contours, groundwater-level change rasters calculated from depth-to-water point values, and groundwater monitoring well locations with groundwater-level data used to develop groundwater-level contours. Groundwater-level contours representing conditions in 1970 (Huxel and Harris, 1969; Rush and Schroer, 1976) and 2006 (Lopes and Allander, 2009) were compiled from previous studies and revised with minor adjustments. Two additional groundwater-level...

This raster dataset represents groundwater-level change from 2007 to 2020 in Smith Valley and Mason Valley, Nevada, calculated using approach 1. For this approach, groundwater-level contours from 2006 and 2020 were interpolated into rasters and differenced to calculate groundwater-level change. Groundwater-level change was estimated using two methods (approach 1 and 2) to address groundwater-level measurement uncertainty and constrain groundwater-level change estimates.
