Chequamegon-Nicolet National Forest Water Quality Database
The Chequamegon-Nicolet National Forest (CNNF) in northern Wisconsin contains numerous groundwater-dependent water resources that may be vulnerable to potential effects of land development, mining, and climate change. In order to monitor water quality over time, 138 of the lakes, streams, wetlands, spring ponds, springs, and wells were sampled in... -
Inventory and Analysis of Flowing Artesian Wells in Bayfield County, Wisconsin
This report presents a county-wide inventory of flowing artesian wells in Bayfield County. Flowing artesian wells are a remarkable resource of high-quality water that both community members and tourists value. This report provides baseline water quality data that are a valuable resource for future assessments. Data collection occurred in 2022. Includes... -
Hydrogeology of the sandy uplands of the Bayfield Peninsula, Wisconsin
The sandy uplands of the Bayfield Peninsula are primary contributors to regional groundwater recharge and provide baseflow to streams in the area. Few data exist, however, to characterize upland hydrogeology or its susceptibility to groundwater contamination. Here, data from two new cores and wells, one existing well, and a lake in the sandy uplands...-

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... -
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...-

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... -
