John M Kilpatrick

John is the Director of the Wyoming-Montana Water Science Center. 

John began his career as a graduate student with the USGS in the Arkansas District in Little Rock, Arkansas. He worked on a variety of groundwater modeling and contamination studies in Arkansas and Nebraska before becoming the Studies Section Chief in the Montana District in 1996. In 2007, became Director of the Montana Water Science Center, which was combined with the Wyoming Water Science Center in 2013.

Temporal changes in the configuration of the water table in the vicinity of the management systems evaluation area site, central Nebraska

To improve understanding of the hydrologic characteristics of the shallow aquifer in the vicinity of the Management Systems Evaluation Area site near Shelton, Nebraska, water levels were measured in approximately 130 observation wells in both June and September 1991. Two water-table maps and a water-level-change map were drawn on the basis of these measurements. In addition, historical data from U

Simulated response of the High Plains aquifer to ground-water withdrawals in the Upper Republican Natural Resources District, Nebraska

The U.S. Geological Survey, in cooperation with the National Soil Tilth Laboratory of the U.S. Department of Agriculture, Agricultural Research Service, conducted a study as part of the multi- scale, interagency Management Systems Evaluation Area (MSEA) program to evaluate the effects of agricultural management (farming) systems on water quality. Data on surface flow, tileflow, and streamflow in t

Geohydrologic characteristics and simulated response to pumping stresses in the Sparta aquifer in East-Central Arkansas

A finite difference digital model of the Sparta aquifer system in Arkansas was developed to aid in assessing the geohydrologic characteristics of the aquifer as well as the impact of withdrawals on water-level declines in the aquifer. The model consists of two layers. The Cockfield aquifer, represented by layer 1, was modeled as a constant head surface. The Sparta aquifer is represented by layer 2

Ground-water resources of the upper White River basin in Arkansas

The upper White River basin in Arkansas lies almost entirely within the Ozark Plateaus physiographic province, which consists of deeply dissected plateaus underlain by limestone, shale, and dolomite. Significant water-yielding units within the upper White River basin include the Eminence and Potosi Dolomites, the Roubidou Formation, the Gasconade Dolomite and the Van Buren Formation, outcrops of u
