The Northern Rocky Mountain region has had scattered infestation of the western spruce budworm Christoneura occidentalis since the early 1900's (U.S. DEPARTMENT OF AGRICULTURE (USDA) 1976b). On the basis of aerial surveys in 1975, TUNNOCK et al. (1976), estimated that budworm defoliation occurred on 2,278,804 acres of six National Forests in Montana. Since the use of DDT was banned in...

This report was prepared by personnel of the Iowa district of the Water Resources Division of the U.S. Geological Survey under the supervision of D. K. Leifeste, District Chief, and Alfred Clebsch, Jr., Regional Hydrologist, Central Region. It was done in cooperation with the State of Iowa and with other agencies. This report is one of a series issued by Iowa. General direction for the...

Hydrologic information for the north-central and western coal-mining regions of Missouri is needed to define the hydrologic system in these areas of major historic and planned coal development. This report describes the physical setting, climate, coal-mining practices, general hydrologic system, and the current (1980) hydrologie data base in these two coal-mining regions. Streamflow in...

Water-level measurements in wells were started by the USGS in Iowa in 1935. Since then a total of about 450 different wells have been measured. The present network consists of about 70 wells. The measurement of these water levels aids in evaluating the present and future water resources of the State. Many factors influence water-level fluctuations. These factors include atmospheric...

Generally, the water quality of Indian Creek-Van Buren watershed is suitable as a source of Municipal, industrial and agricultural water supply and for fish and wildlife. This suitability is based upon comparisons of the existing water quality of Indian Creek to Federal and State water quality standards and criteria developed for the protection of water sources and the fish and wildlife...

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 100 square miles. The report is contained in two...

Data on the East Fork Des Moines River for the August 1979 flood between river miles 330.4 and 408.8 is being published as a supplement to the report "Floods in the Upper Des Moines River basin, Iowa" (Schwab, 1970). Elevation profiles of the 1979 flood, along with previously published profiles, are shown in figures 2-4.

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 are included for all sites where samples were collected at...

This report was prepared by personnel of the Iowa district of the Water Resources Division of the U.S. Geological Survey under the supervision of S. W. Wiitala, District Chief, and Alfred Clebsch, Jr., Regional Hydrologist, Central Region. It was done in cooperation with the State of Iowa and with other agencies. This report is one of a series issued by Iowa. General direction for the...

This report presents selected geologic information derived from wells in a 22-county area of southeastern Iowa. The information was extracted from the Automatic Data Processing (ADP) geologic file of the Iowa and U.S. Geological Surveys. The data presented include location, well identification number, and elevation of the well sites; depth and stratigraphic classification of the bedrock...

To assist the Iowa Department of Environmental Quality in determining the effects that coal mining and attendant activities will have on the water quality of Iowa streams, the U.S. Geological Survey collected three sets of water-quality samples (representative of high, average, and low streamflow) in the White Breast, English,aand Cedar Creek basins in south-central Iowa. These samples...
