Description:
Abstract:
This data set consists of digital water-level-change contours for the High Plains aquifer in the central United States, 1980 to 1995. The High Plains aquifer extends from south of 32 degrees to almost 44 degrees north latitude and from 96 degrees 30 minutes to 104 degrees west longitude. The aquifer underlies about 174,000 square miles in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming.

This digital data set was created from 5,892 wells measured in both 1980 and 1995. The water-level-change contours were drawn manually on mylar. The contours were converted to a digital map at a scale of 1:1,250,000. The data should not be used at scales larger than 1:1,250,000.

Purpose:
This data set was created to document the original map (McGuire, V.L. and Sharpe, J.B., 1997) produced by the High Plains Water-level Monitoring project and to make available the data on this map for use with geographic information systems.

Supplemental_Information:
This data set was re-projected to Stateplane, NAD83, fipszone 2600 for use in the Platte River Cooperative Hydrology Study using the ARCINFO PROJECT command. Introduction --

The information provided in this introduction is found in U.S. Geological Survey Professional Paper 1400-B (Gutentag and others, 1984). This data set consists of digital water-level-change contours for the High Plains aquifer in the United States, 1980 to 1995. The High Plains aquifer, which underlies about 174,000 square miles in parts of eight states, is the principal water source in one of the nation's major agricultural areas. In 1980, about 170,000 wells pumped water from the aquifer to irrigate about 13 million acres.

The High Plains aquifer is a regional water-table aquifer consisting mostly of near-surface sand-and-gravel deposits. In 1980, the maximum saturated thickness of the aquifer was about 1,000 feet and averaged about 200 feet. Hydraulic conductivity and specific yield of the aquifer depend on sediment types, which vary significantly both horizontally and vertically. Hydraulic conductivity ranged from less than 25 to greater than 300 feet per day and averaged 60 feet per day. Specific yields ranged from less than 10 to 30 percent and averaged about 15 percent.

The High Plains aquifer boundaries were determined by erosional extent of associated geologic units and by hydraulic and physiographic boundaries where the High Plains aquifer extends eastward from the Great Plains physiographic province (Fenneman, 1931). In most of the area, the erosional extent of the hydraulically connected Tertiary and Quaternary deposits were used as the aquifer boundary. In eastern Nebraska, streams and physiographic boundaries were used as the aquifer boundary.

Reviews Applied to Data --

This electronic report was subjected to the same review standards that apply to all U.S. Geological Survey reports. Reviewers were asked to check the topological consistency, tolerances, attribute frequencies and statistics, projection, and geographic extent. Reviewers were given digital data sets for checking against the source maps to verify the linework and attributes. The reviewers checked the metadata files for completeness and accuracy.
