Do I need a DNR permit for a pond?
If the pond connects to a navigable waterway, is in a wetland, or involves dam construction, DNR permits are required. Small isolated ponds on private land may not need a DNR permit but may need county permits.
What about a storm water pond?
Stormwater management ponds associated with development projects require municipal approval and potentially DNR permits for discharge.
How big can I dig a pond without a permit?
There is no simple size threshold. Permit requirements depend on location (near waterways, wetlands, floodplain) rather than size alone. County zoning offices can advise on specific sites.
