A Groundwater-Flow Model and Effective Nitrate Calculator for Waupaca, Wisconsin
The City of Waupaca, Wisconsin, uses groundwater pumped from a network of seven high-capacity wells as its municipal water supply. Recent increases in the concentration of nitrate in the municipal water supply raised questions about the source of this contamination and whether it might eventually exceed standards for drinking water. This study combines...-

Hydrogeology and Simulation of Groundwater Flow in Columbia County, Wisconsin
The WGNHS and the U.S. Geological Survey characterized the hydrogeology and developed a groundwater flow model to assess groundwater resources in Columbia County. This report describes regionally extensive aquifers and presents several extensive datasets collected from deep wells across the county. The report also documents the construction and... -
Quaternary Geology of Fond du Lac County, Wisconsin
The Quaternary geology of Fond du Lac County consists of glacial deposits and landforms dating to the last part of the Wisconsin Glaciation (ca. 20,000 to 12,000 yr BP) and nonglacial deposits and landforms of Holocene age (11,700 yr BP to present). Glacial till and meltwater sediment were deposited by the Green Bay and Lake Michigan Lobes of the...-

Potential Effects of Climate Change on Stream Temperature in the Marengo River Headwaters
Cold-water trout habitat in Wisconsin is projected to substantially decrease as a result of climate change. The extent of habitat loss depends, in part, on groundwater discharge to streams, which can provide cool-water refuges for trout. Survey hydrogeologists used field measurements and models of groundwater flow and stream temperature to evaluate how...-

Bedrock Geology of Dodge County, Wisconsin
Dodge County lies in southeast Wisconsin, an area almost entirely covered by glacial deposits. This map interprets the distribution of the buried bedrock units across the county. Geologist Esther Stewart’s refinement of the bedrock elevation contours may help land-use planners identify areas most susceptible to groundwater contamination from applications...-

Water-Quality Indicators of Human Impacts to the Wetlands of Door County, Wisconsin
Door County, the narrow peninsula in eastern Wisconsin, is home to numerous wetlands, many of which are fed by groundwater. Poor-quality groundwater discharging to a wetland can alter the ecology of the wetland and harm native plant and animal communities. This report documents a one-year study of six wetlands. Researchers recorded water quality and... -
