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... -
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...-

Wisconsin Groundwater-Level Monitoring Network Improvements, 2018-2021
This report documents work completed as part of a grant from the U.S. Geological Survey’s National Groundwater Monitoring Network (NGWMN) program. It provides an overview of the Wisconsin Groundwater-Level Monitoring Network (WGLMN) and provides detailed description of well evaluation and repair activities, and drilling of new monitoring wells across 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...-

Characterization of Groundwater Resources in the Chequamegon-Nicolet National Forest, Wisconsin
Results of a comprehensive review and analysis of groundwater resources in the Chequamegon-Nicolet National Forest. The study was divided by location into four reports corresponding to the four main land units: Medford, Nicolet, Park Falls, and Washburn/Great Divide. Each report describes the results of the inventory, modeling, and analysis.-
