The layer was developed using 2017 Dane County LiDAR information and identifies areas in the county where the slopes are > 6% and are required to have additional practices under a USDA NRCS 590 winter spreading plan and Dane County Winter Spreading Permit. This information is provided by Dane County Land & Water Resources Department as an alternative to using soils data to determine the 6% slope threshold for winter spreading restrictions. Due to the inherent nature of karst landscapes, new features can develop at any time. This data layer is not a complete inventory of the entire landscape in any given county and in all cases must be field verified for accuracy. Much of the information presented is the result of local land conservation department staff performing routine field walk-overs as part of conservation program compliance monitoring activities. These counties have voluntarily provided a map of karst feature/sinkhole data collected from multiple sources. Karst Features in Brown, Door, Kewaunee and Manitowoc Counties: No warranty, expressed or implied, is made regarding the accuracy or utility of information depicted on this map.

The Department of Agriculture, Trade and Consumer Protection and University of Wisconsin do not guarantee the accuracy, the applicability for a particular use, the completeness, or the legality of data provided by other sources. It must be field verified to identify additional risk areas such as conduits to groundwater and concentrated flow channels. This map is provided solely as an initial inventory of nutrient spreading risks for nutrient management planning.
