Digital map of saturated thickness in 1980 for the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico,
Oklahoma, South Dakota, Texas, and Wyoming
Dataset Identification:
Resource Abstract:
This digital data set consists of saturated thickness contours for the High Plains aquifer in the central United States. The
High Plains aquifer extends from south of 32 degrees to almost 44 degrees north latitude and from 96 degrees 30 minutes to
106 degrees west longitude. The outcrop area covers 174,000 square miles and is present in Colorado, Kansas, Nebraska, New
Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital data set was created by digitizing the saturated thickness
contours from a 1:1,000,000-scale base map created by the U.S. Geological Survey High Plains Regional Aquifer-System Analysis
(RASA) project (Gutentag, E.D., Heimes, F.J., Krothe, N.C., Luckey, R.R., and Weeks, J.B., 1984, Geohydrology of the High
Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming: U.S. Geological
Survey Professional Paper 1400-B, 63 p.) The data are not intended for use at scales larger than 1:1,000,000.

on those maps for use with geographic information systems.

Additional information on resource:
Introduction -- The information provided in the introduction is found in U.S. Geological Survey Professional Paper 1400-B
(Gutentag and others, 1984). This data set consists of digital saturated thickness contours for the High Plains aquifer in
the United States. 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. The maximum saturated thickness of the aquifer in 1980 was about 1,000 feet and averaged 200 feet.
Hydraulic conductivity and specific yield were highly variable because of the heterogeneity of the aquifer. 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 the erosional
extent of the High Plains aquifer and hydrologic 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 hydraulically connected Tertiary
and Quaternary rocks were used. Streams and physiographic provinces in eastern Nebraska were used as hydrologic boundaries
of Quaternary deposits. This digital data set was created by digitizing the saturated thickness contours from a 1:1,000,000-scale
base map created by the High Plains RASA project (Gutentag and others, 1984). Reviews Applied to Data -- This electronic report
was subjected to the same review standard that applies 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. Related Spatial and Tabular Data Sets -- Other References Cited -- Fenneman,
