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...

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...

These contours represent water level change in the shallow aquifer in Lahontan Valley from 1992 - 2012 based on depth-to-groundwater measurements made in 73 wells in 1992 and 2012, with limited measurements made in 2013. Measurements collected in 2013 were used to develop the contours only in limited cases where the measurement well was being pumped or was inaccessible in 2012. Water-level change in the shallow aquifer was determined by differencing measurements made in 1992 with current measurements. The difference values were used to interpolate a change surface and contours were developed from that surface.

This raster dataset represents groundwater-level change from 2007 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 2006 and 2020. Point values of change were interpolated into a raster to calculate valley-wide 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.
