This statewide dataset shows the location of Wisconsin Permit Discharge Elimination System (WPDES) Surface Water Outfalls. This dataset was last updated Summer, 2007.

You may use this online data set for planning, but to verify that a waterbody has an outfall discharge is to request information from the local WDNR Permit Program contact.
