Preliminary report on the Pierre Shale in North Park, Colorado, and its correlation to Boulder, Middle Park, and Northwest Colorado
Dawn H. Madden
1979, Open-File Report 79-729
The Pierre Shale consists of interbedded marine shale and sandstone representing nearly continuous marine sedimentation during Late Cretaceous time. The Pierre Shale and time-equivalent marine units in the western interior United States contain 28 ammonite range zones. The ammonites show such rapid evolution and such wide geographic extent that their...
Chemical analyses of surface water in Illinois, 1975-77--Volume II, Illinois River basin and Mississippi River tributaries north of Illinois River basin
David Grason, R. W. Healy
1979, Water-Resources Investigations Report 79-24
Samples of surface water were collected and analyzed by the Illinois Environmental Protection Agency. The results from water years 1975 to 1977 are presented in three volumes. The history of sampling and analytical methods used during that period are summarized. Stream discharge data from records of the U.S. Geological Survey...
Analysis of water-level fluctuations of Lakes Winona and Winnemissett-- two landlocked lakes in a karst terrane in Volusia County, Florida
G.H. Hughes
1979, Water-Resources Investigations Report 79-55
The water levels of Lakes Winona and Winnemissett in Volusia County, Fla., correlate reasonably well during dry spells but only poorly during wet spells. Disparities develop mostly at times when the lake levels rise abruptly owing to rainstorms passing over the lake basins. The lack of correlation is attributed to...
River mileages and drainage areas for Illinois streams—Volume 2, Illinois River basin
R. W. Healy
1979, Water-Resources Investigations Report 79-111
River mileages are presented for points of interest on Illinois streams draining 10 square miles or more. Points of interest include bridges, dams, gaging stations, county lines, hydrologic unit boundaries, and major tributaries. Drainage areas are presented for selected sites, including total drainage area for any stream draining at least...
Generalized thickness of the confining bed overlying the Floridan Aquifer, Southwest Florida Water Management District
Anthony Buono, R. M. Spechler, G. L. Barr, R. M. Wolansky
1979, Open-File Report 79-1171
This map presents the thickness of the confining bed overlying the Floridan aquifer in the Southwest Florida Water Management District and adjacent areas. The bed separates the surficial aquifer from the underlying Floridan aquifer. Lithologic logs and information from quarries were used in conjunction with an unpublished map to compile...
Generalized thickness of the surficial deposits above the confining bed overlying the Floridan Aquifer, Southwest Florida Water Management District
R. M. Wolansky, R. M. Spechler, Anthony Buono
1979, Open-File Report 79-1071
This map report presents the thickness of the surficial deposits overlying the upper confining bed of the Floridan aquifer in the Southwest Florida Water Management District. The surficial deposits range in thickness from less than 25 feet in the western part of the district to greater than 250 feet in...
The effect of nitrification in the oxygen balance of the Upper Chattahoochee River, Georgia
Theodore A. Ehlke
1979, Water-Resources Investigations Report 79-10
Oxygen consumption as a result of nitrification, and carbonaceous bacterial oxidation were compared in a 108 kilometer reach of the Chattahoochee River, Georgia. Nitrogenous and carbonaceous oxygen consumption were separated by using an inhibitor of nitrification 1-allyl-2-thiourea. The comparison was conducted in the laboratory using samples collected from the water...
