Macroinvertebrate assemblages and environmental variables were evaluated as part of the Idaho statewide surface-water quality monitoring program during 1996–98. Two assessment approaches were used to evaluate the macroinvertebrate data collected from Idaho rivers—biological metrics and multivariate statistical analyses. A total of 247 macroinvertebrate taxa were identified in semiquantitative riff

Water-resources data for the 2000 water year for Texas are presented in six volumes, and consist of records of stage, discharge, and water quality of streams and canals; stage, contents, and water-quality of lakes and reservoirs; and water levels and water quality of ground-water wells. Volume 5 contains records for water discharge at 71 gaging stations; stage only at 4 gaging stations; stage and

The County Road A disposal site, located on the Bad River Indian Reservation, Ashland County, Wisconsin, contains papermill sludge generated by a former mill in the City of Ashland. Since the time of disposal (1968-1970) the site has been the subject of investigations by the U.S. Bureau of Indian Affairs, the U.S. Environmental Protection Agency, and private consultants. During 1997- 1998, an inve

Volume 2 contains records for water discharge at 49 gaging stations; stage only at 3 gaging stations; stage and

Analyses and interpretation of water quality, sediment, and biological data from water years 1986 through 1998 indicated that land use and other human activities have had only minimal effects on water quality in the Wolf River upstream from and within the Menominee Indian Reservation in northeastern Wisconsin. Relatively high concentrations of calcium and magnesium (natural hardness), iron, mangan

Nutrient and suspended-sediment data were collected on major tributaries to the St. Croix River during 1997-99 as part of three studies. The first study, done in 1997 as part of the U.S. Geological Survey?s National Water-Quality Assessment Program Upper Mississippi Study Unit, was a widespread synoptic survey of nutrient and suspended-sediment concentrations, loads, and yields during snowmelt.

IntroductionThe Water Resources Division of the U.S. Geological Survey, in cooperation with State, municipal, and Federal agencies, collects a large amount of data pertaining to the water resources of Pennsylvania each water year. These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of the water resources of the State. To make th

Water-resources data for the 1999 water year for Ohio consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report, in two volumes, contains records for water discharge at 120 gaging stations and 69 partial-record sites; water levels at 187 observation wells and 26 crest-stage
