Guidelines for collection and field analysis of water-quality samples from streams in Texas
F.C. Wells, W.J. Gibbons, M.E. Dorsey
1990, Open-File Report 90-127
This manual provides standardized guidelines and quality-control procedures for the collection and preservation of water-quality samples and defines procedures for making field analyses of unstable constituents or properties. Descriptions and procedures are given for several methods of sampling for which a variety of samplers may be used. Sample-processing devices such as...
Effects of surface coal mining and reclamation on the geohydrology of six small watersheds in West-Central Indiana
Jeffrey D. Martin, Richard F. Duwelius, Charles G. Crawford
1990, Water Supply Paper 2368-B
Six small watersheds in west-central Indiana were selected for study of the hydrologic effects of surface coal mining and reclamation. The watersheds include mined and reclaimed, mined and unreclaimed, and unmined agricultural land uses and are each less than 3 square miles in area. Surface-water, ground-water, and meteorologic data for...
Ground-water levels in the alluvial aquifer in Eastern Arkansas, 1989

Surface-water hydrology and salinity of the Anclote River estuary, Florida
Mario Fernandez Jr.
1990, Water-Resources Investigations Report 89-4046
Direct measurements of streamflow, tides, and salinity in the Anclote River Estuary, Florida were made during the period January 1984 through May 1986; historical streamflow was compared to that measured during the study; the influence of well-field pumpage on streamflow was evaluated; and regression relations between salinity, tide, and average...
A summary of water-resources activities of the U.S. Geological Survey in Iowa; fiscal year 1990
1990, Open-File Report 90-583
Water resources activities of the U.S. Geological Survey in Iowa consist of collecting hydrologic data and conducting interpretive studies. Hydrologic investigations in Iowa are made through three basic types of projects: (1) hydrologic data-collection programs; (2) local or areal hydrologic studies; and (3) statewide or regional investigations. These projects are...

W.J. Haire, C. Price
1990, Water Data Report FL-89-2A
Water resources data for the 1989 water year in Florida consists of continuous or daily discharge for 295 streams, periodic discharge for 36 streams, miscellaneous discharge for 75 streams, continuous or daily stage for 154 streams, periodic stage for 13 streams, peak discharge for 57 streams, continuous daily tide stage...
Invertebrate communities of small streams in northeastern Wyoming
D. A. Peterson
1990, Water-Resources Investigations Report 85-4287
Invertebrate communities of small streams in an energy-mineral- development area in the Powder River structural basin of northeastern Wyoming were studied during 1980-81. The largest average density of benthic invertebrates among 11 sites was 983 invertebrates/sq ft at a site on a perennial stream, the Little Powder River at State...
