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 regulation, classified trout water, public land and DNR fishing easements.

Wisconsin boasts over 13,000 miles of trout streams; deciding on just one place to fish 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:

  • 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 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 accuracy, completeness or legality of the information herein. 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 that 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, and 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.
