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.

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).

Includes all relevant data for road stream crossing inventories including passability ratings. To see photos for a given crossing, select it and scroll all the way down to the bottom of the attribute table for attachments. Complete passage barriers prevent passage for all life stages of brook trout.Juvenile passage barriers prevent passage by juvenile brook trout.

Features from the 1:24,000 scale National Hydrography Dataset (NHD) were used to depict inland stream trout and salmon type regulations. NHD features were altered to fit the extent of the regulations described in FO 200 and FO 210. Except for streams in the Michigan-Wisconsin Boundary Waters, any other inland stream not classified by type (1-4; GR, RA, BTRA) are still subject to trout and salmon fishing regulations as described on page 40 of the Michigan Fishing Guide. Please see pp. 24-25 for Michigan-Wisconsin Boundary Waters regulations. Note that the two inland stream trout and salmon regulation GIS layers only show the streams classified by type; these layers do not include any streams that are not classified by type. The regulation type associated with a stream feature is indicated in the RegulationType field and the designation status is indicated in the Designated field (with 0 as non-designated and 1 as designated). The RegulationType and Designated field are concatenated in the RegTypeDes to show the full type regulation and designation status. In some cases, a stream will have more than one regulation type assigned. In which case, the RegulationType field will have both types listed, as will the RegTypeDes field. Each regulation type is associated with specific rules for the length of the fishing and possession seasons, minimum size limits, and daily possession limits. See FO 200 and the Michigan Fishing Guide for more details about the individual regulation types. Regulation types are as follows: Type 1 – Type 1 Trout Stream; Type 2 - Type 2 Trout Stream; Type 3 - Type 3 Trout Stream; Type 4 - Type 4 Trout Stream; BTRA – Brook Trout Restoration Area; RA - Research Area Trout Stream; GR - Gear Restricted Stream. Designation status is either designated or non-designated. Designated trout streams are inland streams containing a significant population of trout or salmon, as identified by the State of Michigan. Designated trout streams are protected from certain activities, see the Michigan Fishing Guide or FO 210 for more details. All Type 1, Type 2, GR, RA, and BTRA are designated trout streams. Most Type 3 and Type 4 streams are designated trout streams. The main layer shows the majority of inland streams that are classified by type for trout and salmon regulations. However, there are some polygon features that cannot be displayed in this line layer and are represented in the BTRA polygon layer. To show all inland streams that are classified by type for trout and salmon regulations, both layers must be displayed in the proper order using established symbology. The BTRA polygon layer should be displayed on the top of the main stream regulations layer. When displaying the inland trout and salmon streams with inland trout and salmon lakes Types A-F & Special Type, both of the stream layers should be displayed underneath the Types A-F & Special Type layer. For the main regulation type layer, set the drawing order so that specific regulations type display on top of others. Do this by opening the feature class properties in the Table of Contents in ArcMap, then go to Symbology, then Advanced, then Symbol levels and using the following order, from top to bottom: Type 4 Non Designated, Type 3 Non Designated, GR Type 4 Designated, GR Type 2 Designated, GR Type 1 Designated, GR Designated, RA Designated, Type 4 Designated, Type 4 BTRA Designated, Type 3 Designated, Type 3 BRTA Designated, Type 2 Designated, Type 1 Designated, and Type 1 BTRA Designated.

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.
