These polygon and line data layers represent Wisconsin DNR previously impaired waters for the State of Wisconsin in 2016.[The waters in this data layer are those which have been listed and subsequently removed from Wisconsin's list of Impaired Waters. The condition of these waters has been restored so that water quality standards are now met. Each water has its own story of degradation, discovery, restoration, monitoring, and removal from the list.]
