This feature layer contains Wisconsin hydro flowlines, area hydrography features and culvert lines created and developed by Wisconsin Department of Natural Resources DNR IT GIS Section as part of a pilot project to remap rivers, lakes and streams in Wisconsin coastal counties and HUC 8 watersheds at a scale of 1:5,000 (also referred to as 5k Hydro). WDNR staff used the most current Lidar DEM for each county as the input to the ACPF toolbox to create accumulation derived flowpaths. Waterbody area features and culverts were developed using Lidar breaklines, existing 24k GIS features, and digitization from multi-year aerial photography. Collection protocols followed USGS NHD digital elevation hydrography creation guidelines.Data DictionaryThis pilot project was funded by the Wisconsin Coastal Management Program and the National Oceanic and Atmospheric Administration, Office for Coastal Management under the Coastal Zone Management Act, Grant # NA21NOS4190086Dataset last Updated 4/22/2025.

Wild and Scenic Rivers are established to protect natural streams, to attract out–of–state visitors, to assure the well–being of our tourist industry, and to preserve some rivers in a free-flowing condition and protect them from development. This dataset is useful for locating recreation opportunities on free-flowing Wisconsin Rivers. More information on Wisconsin’s Wild and Scenic Rivers can be found at the DNR’s page on Wisconsin’s wild and scenic rivers.

This layer consists of a 1:250,000-scale polygon coverage containing depth-to-bedrock estimates used in preparing the GCSM for Wisconsin. The primary source for this data layer is a 1973 map at 1:1,000,000 scale published by the WGNHS and USGS. Where more recent information was available, the USGS updated the 50-foot and 100-foot contours of the depth-to-bedrock map at a scale of 1:250,000. Soil associations data, and other information,were used to add a 5-foot contour to the data layer.See the usage documentation (https://www.arcgis.com/home/item.html?id=e1e89ae505594459a46407f1daf4ad5d) and the Full report (https://www.arcgis.com/home/item.html?id=fd4d0c43abc04b4ab915586d9a0e89dd) for more information.

This service is NOT for download but may be viewed in web maps and apps.Georeferenced Statewide Bedrock Geologic Map of Wisconsin, 1982. The Statewide Bedrock Geologic Map of Wisconsin was developed to provide a reliable, accurate and detailed representation of the state’s subsurface geology. It supports a variety of applications, including geological research, land-use planning, resource management, environmental conservation, education, public outreach, and policy development. By offering insights into the composition, structure, and distribution of bedrock formations, the map aids in identifying potential geological hazards and areas of scientific or ecological significance and helps planners, researchers, and decision-makers make informed choices.

The statewide geologic map symbol for each formation is standardized for consistency and can be found in the accompanying legend. The legend provides essential information, including formation names, lithologic descriptions, geologic age, and the symbology used in the dataset. This map and its data were developed by UW Extension-Geologic and Natural History Survey (WGNHS), Meredith E. Ostrom. Visit WGNHS Maps & Publications search for WGNHS maps and contact WGNHS at info@wgnhs.wisc.edu with any questions about this map or data. The map was georeferenced for use in this service by the Wisconsin DNR Bureau of Drinking Water and Groundwater, Water Use Section. For any questions contact the Bureau of Drinking Water and Groundwater GIS Analyst at DNRDGGISAPPS@wisconsin.gov. This data was mapped at a very small scale (ranging from 1:5,000,000 to 1:500,000), making it unsuitable for detailed local analysis or site-specific decision-making. Users are advised to consult local or higher-resolution datasets when conducting detailed analyses or making critical decisions.

This dataset contains DNR Managed Lands as parcels with local property name, and GIS and deed acreages. Parcels are symbolized as fee simple (DNR Owned), DNR easement on private land (open/restricted public access) and DNR lease on federal- and county-owned land. This dataset does not contain closed fee or easement. See metadata/data dictionary for interest (transaction type) classification.The parcels are digitized from deed legal description and based on the DNR Landnet System (Public Land Survey System), Wisconsin Transverse Mercator. This data is updated on a weekly basis.This layer represents the geometry of the real estate holdings of the Wisconsin Department of Natural Resources and is not to be interpreted as representing legal property boundaries.

Wisconsin's Outstanding and Exceptional Resource Water (OERW) designations are designed to include Wisconsin's cleanest waters. The OERW dataset was first developed in the 1990s using narrative descriptions from the state’s OERW designations described in NR102 and the state’s 1:24,000 scale hydrography dataset using 7.5 minute USGS topographic quadrangle maps. The OERW spatial data quality has been reviewed by GIS specialists working with biological field staff and using more detailed landmarks and data over time. The accuracy of the delineations continue to improve with the use of improved technologies and tools. Year 2006 designations were derived by selecting and copying applicable features from the 1:24,000 scale hydrography dataset.

This data set is a polygon feature class representing Wisconsin DNR Turkey Management Zones. Turkey Management Zones indicate the areas with various turkey hunting regulations throughout Wisconsin. Hunting regulations may vary between and within zones. Users should consult the most recent Hunting Regulations Handbook to determine which regulations apply to which zones, or portions of zones.

Wisconsin's Watershed data layer contains 330 delineated watersheds created initially for the Priority Watershed Program. Basins and watersheds are interconnected areas of land draining from surrounding ridge tops to a common point such as a lake or confluence with a neighboring land area.These watersheds were originally delineated by Wisconsin DNR for the Nonpoint Source Water Pollution Abatement Program, also generally known as the Priority Watershed Program. They generally indicate areas that drain into a common river system or lake, but may also be based on DNR basin management criteria.
