Soil erosion from construction sites has long been identified as a significant source of sediment and other suspended solids in runoff in many parts of the United States (Hagman and others, 1980; Yorke and Herb, 1976: Becker and others, 1974). In some states, such as Wisconsin, sediment has been identified as the number one pollutant (by volume) of surface waters (Wisconsin Depart- ment...

Intense recreational use of Geneva Lake and extensive residential and other development in its watershed (fig. 1) has created concern over a possible decline in water quality of the lake. Because of this concern, a collaborative effort between the U.S. Geological Survey (USGS), Wiscon- sin Department of Natural Resources (WDNR), and the Geneva Lake Environmental Agency was begun to...

Data that describe the physical characteristics of stream subbasins upstream from selected sites on streams in the Des Moines River, Upper Des Moines River, and East Fork Des Moines River Basins, located in southwestern Minnesota, and northwestern Iowa, are presented in this report. The physical characteristics are the drainage area of the subbasin, the percentage area of the subbasin...

Data that describe the physical characteristics of stream subbasins upstream from selected sites on streams in the Upper Wapsipinicon River, Upper Cedar River, Shell Rock River, and Winnebago River Basins, located in southern Minnesota and northern Iowa are presented in this report. The physical characteristics are the drainage area of the subbasin, the percentage area of the subbasin...

This report presents the water-quality data collected during 1998-99 from the land owned by the Prairie Island Indian Community at the northern end of Prairie Island, Minnesota. The data were collected by the U.S. Geological Survey in cooperation with the Prairie Island Indian Community. Seventeen monitoring wells were installed by the U.S. Geological Survey in 1998. Fifteen of the wells...

There are seven types of aquatic resources on the Grand Portage Reservation. An ecological monitoring program was proposed for these resources. Some of the resources are pristine, while others have been affected by development. Each type of resource has physical (habitat, sediment, and hydrology), chemical, and biological (fish, invertebrates, and algae) characteristics that are...

In small streams, flow and water-quality concentrations often change quickly in response to meteorological events. Hydrologists, field technicians, or locally hired stream ob- servers involved in water-data collection are often unable to reach streams quickly enough to observe or measure these rapid changes. Therefore, in hydrologic studies designed to describe changes in water quality...

The Trout Lake Watershed is in the Northern Highlands Lake District in north-central Wisconsin. The study area includes four subbasins with five lakes and two bog lakes. The objectives of the Trout Lake WEBB project are to (1) describe processes controlling water and solute fluxes in the Trout Lake watershed, (2) examine interactions among those processes and (3) improve the capability...

Nitrogen (N) was added for 35 days in the form of 15NH4Cl to Kings Creek on Konza Prairie, Kansas. Standing stocks of N in key compartments (that is, nutrients, detritus, organisms) were quantified, and the amount of labeled N entering the compartments was analyzed. These data were used to calculate turnover and flux rates of N cycling through the food web, as well as nutrient...

The objectives of this study are to provide continuous discharge records for selected rivers at specific sites to supply the needs for regulation, analytical studies, definition of statistical properties, trends analysis, determination of the occurrence, and distribution of water in streams for planning. The project is also designed to determine lake levels and to provide discharge for...

A better understanding of the ground-water and surface-water resources of the Rock River Valley in southwestern Minnesota was needed due to concerns surrounding future reliable sources of water for public supply. The Rock River Valley aquifer consists of a surficial sand and gravel unit that underlies the entire Rock River Valley and a buried sand and gravel unit that is present only in...
