Preliminary map showing freshwater heads for the Mission Canyon and Lodgepole limestones and equivalent rocks of Mississippian age in the Northern Great Plains of Montana, North Dakota, South Dakota, and Wyoming

Abstract:

A potentiometric-surface map showing freshwater heads for the Mission Canyon and Lodgepole Limestones of Mississippian age has been prepared as part of a study to determine the water-resources potential of the Mississippian Madison Limestone and associated rocks in the Northern Great Plains of Montana, North and South Dakota, and Wyoming. Most of the data used to prepare the map are from drill-stem tests of exploration and development wells drilled by the petroleum industry from 1946 to 1978. Some data are also from cased oil wells, water-production wells, and springs. A short explanation describes the seven categories of reliability used to evaluate the drill-stem-test data and identifies several factors that might explain the apparent anomalous highs and lows on the potentiometric surface. The map is at a scale of 1:1,000,000 and the potentiometric contour intervals are 100, 200, and 500 feet. (USGS)
