Located in the south-central portion of the state, new geologic mapping of the frequently-visited Baraboo Hills has resulted in a revision of the stratigraphy of the Precambrian-aged bedrock. The Baraboo Quartzite is now divided into four informal members, and the maximum depositional age for the Baraboo Quartzite is 1714±17 million years old. These...

Three-dimensional bedrock mapping of Grant County at a scale of 1:100,000 provides new baseline information on the distribution of geologic units. Grant County contains Paleozoic bedrock units ranging in age from Silurian to Cambrian. Gentle folds and small faults deform the Paleozoic sequence and were mapped based on structure contours of the base of the...

The Quaternary geologic map of Jefferson County, Wisconsin, provides details about the surficial sediment and landscapes that were formed largely in the footprint of the Laurentide Ice Sheet's southern Green Bay Lobe during the late Wisconsin Glaciation (ca. 20,000 years before present). These landscapes include lowlands underlain by glacial and...

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...

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...

Columbia, Green Lake, and Marquette Counties were glaciated during the last ice age, and large areas were inundated with water from proglacial lakes and large meltwater rivers that occupied the valleys of the existing Wisconsin and Fox Rivers. These processes resulted in rolling upland hills, including drumlins punctuated by low-lying areas dominated by...

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...

Report, database, field protocol, photos, and site sketches documenting the multi-year project inventorying springs in Wisconsin with discharge rates of at least 0.25 cubic feet per second.

This report documents the groundwater flow model that was developed for western Chippewa County, Wisconsin. It also presents analyses that were run to evaluate how industrial sand (frac sand) mining and irrigated agriculture--might affect the water table and base flows of nearby headwater streams.

All of what is now Calumet and Manitowoc Counties was covered by ice during the last great glaciation, between 30,000 and 11,000 years ago. This bulletin explains the glacial history, interprets the deposits left behind, and portrays the distribution of the deposits on a map and cross sections. This report should be useful to planners and development...

The bulletin describes the state-of-the-art scientific tool that can be used to help make good decisions about high-capacity well placement and pumping, as well as land use in Wisconsin's Central Sands region. It can also be used to predict which wells and well locations would have the greatest impact on nearby lakes and streams. The user's manual...

Traces the complex glacial history of Door County. Map shows glacial units with shaded relief.

The 2016 groundwater flow model is a three-dimensional model using state-of-the-art representation of the hydrogeology of Dane County. This report describes the model, appendices provide data, and the user's manual provides basic instructions and recommendations for running the model.

Kewaunee County, at the southern end of the Door Peninsula, was overrun by glaciers many times. Author Lee Clayton describes the county's complex glacial geology, from the surface soil down to solid rock. The accompanying map shows the placement of glacial sediments as well as glacial and post-glacial stream and lake sediments.

Hydrogeologists at the Survey developed a groundwater management tool to help guide land-use decisions in Dane County. The publication describes the inputs used to calculate recharge and includes a reduced-scale version of the recharge map. A full-scale version of the recharge data has been subsequently added as Dataset 1.

This report traces the advances and retreats of glaciers through Sheboygan County in eastern Wisconsin. Available as a bulletin, map, cross sections, and GIS data.
