T.R.O.U.T - Trout Regulations and Opportunities User Tool

Fishing Wisconsin

TROUT graphic

The Trout Regulations & Opportunities User Tool (TROUT) was designed to help trout anglers find places to fish. TROUT includes trout fishing regulations, classified trout water, public land and DNR fishing easements.

Wisconsin boasts over 13,000 miles of trout streams; deciding on just one fishing place can be daunting. TROUT will help anglers optimize their time on the water by showing where the publicly accessible land is relative to roads, bridge crossings, and trout streams. Exploring trout water just got easier.

This tool provides anglers with the following:

  • On-the-go mobile access to trout streams and regulations
  • Roads, aerial images, and fishing easements
  • The ability to find your location, measure distances, and print/save a customized map for a fishing trip
  • NEW! Trout habitat project locations and details from 2011 through 2016

This web mapping application is powered by Geocortex Essentials middleware and provides a robust, intuitive platform to display geometry, perform spatial analysis and create custom maps. Microsoft Silverlight plug-in must be loaded on the computer for Geocortex Essentials to open. Get the free download [exit DNR].

Are Managed Forest Lands (MFL) available on this map?
No, private forest lands open to public recreation through Managed Forest Law and Forest Crop Law programs are unavailable on this map. See Private Forest Lands Open to Public Recreation Web mapping application. Easements held by county and private conservation organizations are also not available.

Are private lands (plat books) available on this map?
No, they are not available on this map. This web map contains those lands that, for the most part, are open to the public. For more information, see plat books and land ownership maps [exit DNR] or your county office.

How do I see additional detail?
You can zoom in or out using the mouse's scroll wheel. Users can also press the "Zoom In" or "Zoom Out" buttons on the left side of the map.

How do I find out detailed information for a specific site?
After you've zoomed in on your specific site, click on the trout regulations layer, and a pop-up describing the bag limit and season will appear. Select the "Point Identify" button from the menu or toolbar. Then click on the site. A name should appear in the column on the left side of the map. Click on the title, and a pop-up box with specific information will appear.


This map is not intended to be an exhaustive display of publicly accessible waters. For example, it doesn't include county-owned easements or easements held by conservation organizations. DNR and Stewardship Easements are private lands open for public access. However, not all nature-based activities may be allowed.

No warranty, express or implied, is made regarding the information's accuracy, completeness or legality. The boundaries depicted on this map do not represent the legal ownership boundaries of any property. The delineation of legal boundaries may only be conducted by a licensed surveyor.

DNR web mapping applications contain the most current information about DNR properties and private lands under DNR management with public access for hunting and recreational activities. Please be aware that 3rd party web mapping applications (e.g., Google Maps, commercial mapping companies, etc.) may display erroneous boundaries of these properties. To ensure you can reach your intended area and avoid trespassing, use DNR web mapping applications to plan your outing. Confirm the ownership of non-DNR public land (e.g., municipal, county, federal), tribal land, and private land through other means. Also, recognize that on-ground postings and property boundary signs override property boundaries shown in DNR and 3rd party web mapping applications and should be respected.
