Trout Waters are represented by Class I, Class II or Class III waters. These classes have specific ecological characteristics and management actions associated with them. For more information regarding Trout Classifications, see the Fisheries Trout Class Webpages. (https://dnr.wi.gov/topic/fishing/trout/streamclassification.html)*anglers can also use the classified trout maps for each county at the DNR’s Trout Stream Maps page or use the Trout Regulations and Opportunities User Tool (TROUT) to locate fishing opportunities.

The layer represents Wisconsin DNR trout habitat management project points. Trout habitat management projects include activities such as maintaining trout streams, improving existing streams and restoring streams capable of sustaining trout populations. Projects are managed through the Inland Trout Program which is funded through the Inland Waters Trout Stamp Program revenues, sales of patron licenses and collector stamps, general fishing license fees, federal Sport Fishing Restoration (SFR) funding and donations. For more information about the Inland Trout Program please visit https://dnr.wi.gov/topic/fishing/trout/InlandManagement.html Trout Habitat Projects are represented by points or lines depending on the level of detail of geographic reporting for a given project. Projects represented as lines represent the full extent of the project along the stream while projects represented by points are either site specific projects or represent the starting location of project.

For more information regarding Trout Classifications, see the Fisheries Trout Class Webpages. (https://dnr.wi.gov/topic/fishing/trout/streamclassification.html). This dataset contains information on the location, size, and trout classification of over 100 trout spring ponds.*Anglers can also use the classified trout maps for each county at the DNR’s Trout Stream Maps page or use the Trout Regulations and Opportunities User Tool (TROUT).

Trout Regulations depict bag limits and season for inland and Great Lakes trout fishing. To view written descriptions of the regulations visit http://dnr.wi.gov/topic/fishing/regulations/TroutRegs.html

For general fishing rules, which also apply to trout fishing refer to the most current Guide to Wisconsin hook and Line Fishing Regulations (Publication FH-301). This layer is an interpretive summary of Wisconsin’s fishing laws and regulations. For complete fishing laws and regulations, consult the Wisconsin State Statutes

Chapter 29 or the Administrative Code of the Department of Natural Resources. Consult the legislative website - (http://docs.legis.wisconsin.gov/code/admin_code/nr/001/20).

These streams are Priority Navigable Waters under the State of Wisconsin's Waterways Protection Program. Priority Navigable Waterways include lakes less than 50 acres, waters with self-sustaining musky, sturgeon and walleye populations, tributaries to and rivers connecting naturally reproducing populations, and perennial tributaries to trout streams.

This layer is intended for use in the Wisconsin PFAS Interactive Data Viewer GIS mapping application, use for any other purpose should be done with caution to avoid misuse or misinterpretation of information contained in this layer. Please seek appropriate DNR staff support.This layer contains Wisconsin waterbody polygons, including lakes or portions of streams and rivers, where fish have been found to contain high levels of PFAS and limited fish consumption is advised. More information about specific consumption advisories is available at Consumption Advisories and PFAS.All determinations of Consumption Advisories are handled by the DNR Division of Fish, Wildlife and Parks. For more on all Consumption Advisories in Wisconsin see the Eating Your Catch webpage.This information should be used with the polyline data in the layer called "EM PFAS - PFAS-Based Consumption Advisory - Stream/River Lines" to see all of the information on PFAS-related fish consumption advice in Wisconsin.
