Aquifer test to determine hydraulic properties of the Elm aquifer near Aberdeen, South Dakota
Bryan D. Schaap
2000, Water-Resources Investigations Report 2000-4264
The Elm aquifer, which consists of sandy and gravelly glacial-outwash deposits, is present in several counties in northeastern South Dakota.

Assessment of freshwater mussels in the Allegheny River at Foxburg, Pennsylvania, 1998
Robert M. Anderson
2000, Water-Resources Investigations Report 2000-4058
The upper reaches of the Allegheny River are a high-quality resource that supports populations of a number of endangered species. Two endangered species of freshwater mussel, the northern riffleshell, Epioblasma torulosa rangiana, and clubshell, Pleurobema clava, are present in this river reach. Prior to a bridge-replacement project at the Allegheny...
Simulation of projected water demand and ground-water levels in the Coffee Sand and Eutaw-McShan aquifers in Union County, Mississippi, 2010 through 2050
Susan S. Hutson, E. W. Strom, D.E. Burt, M. J. Mallory
2000, Water-Resources Investigations Report 2000-4268

Hydrologic aspects of the 1998-99 drought in the Delaware River basin
Gary N. Paulachok, Bruce E. Krejmas, Heidi L. Soden
2000, Water-Resources Investigations Report 2000-4112
A notable drought in the Delaware River Basin during late 1998 and most of 1999 had a major effect on surface and subsurface components of the hydrologic system. The drought conditions resulted from anomalous patterns in the general atmospheric circulation that diverted Gulf and subtropical Atlantic moisture away from the...
Digital Map of Water-Level Changes in the High Plains Aquifer in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming, 1980 to 1997
Brian C. Fischer, Keith M. Kollasch, Virginia L. McGuire
2000, Open-File Report 2000-96
This data set consists of digital water-level-change contours for the High Plains aquifer in the central United States, 1980 to 1997. 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....

Joyce E. Williamson, Timothy Scott Hayes
2000, Water-Resources Investigations Report 2000-4220
During the 1980?s, significant economic development and population growth began to occur in Lawrence County in the northern part of the Black Hills of western South Dakota. Rising gold prices and heap-leach extraction methods allowed the economic recovery of marginal gold ore deposits, resulting in development of several large-scale, open-pit...
