Michigan DNR Management Unit Boundaries for different DNR Divisions.

Michigan Department of Natural Resources Law Enforcement Division Area boundaries. This layer shows the boundary of the areas and provides information about its associated district.

Project boundaries are geographic lines that help define the state’s public lands acquisition and disposal strategy (Michigan's Managed Public Land Strategy). As part of the strategy, we will improve project boundary alignments of public lands to more closely reflect actual land ownership. There currently are about 1.9 million acres of privately owned lands scattered within the project boundaries. These boundaries were approved by the Natural Resources Commission in March, 2020.

Boundary line depicting the applicable extent for the Lake Michigan Coastal Program grants. The Lake Michigan Coastal Program is based on a watershed approach. The boundary for the program, the Coastal Program Area, includes those areas that drain into Indiana's portion of Lake Michigan. The Coastal Program Area boundary defines the areas that will be eligible to participate in the program. More information about the Coastal Program Area can be found in Chapter 3 of the Lake Michigan Coastal Program document. For more information: https://www.in.gov/dnr/lakemich/6039.htm.

Feature service of DNR managed GIS data to be published on the MI DNR Open Data site.

This feature class is an inventory of stream crossings, culverts, and bridges in the Great Lakes Region. Data gathered and contained in this feature class is based on the Great Lakes Stream Crossing Inventory Protocol.

Whole grids from the v3.3 Michigan Great Lakes Grids GIS layer were assigned to statistical districts to match boundaries in existing GIS layers (see maps 1-3 in the 2000 Consent Decree). The Dissolve tool in ArcGIS 10.5 was used to dissolve the Michigan Great Lakes Grid layer (v3.3) to create statistical district boundaries that were then bounded by waterbody descriptions as follows: 1) The MI-8 and MH-1 statistical districts were clipped to end at the boundary of the St. Mary’s River as described in the 2000 Consent Decree. 2) MH-6 was clipped to end at the Blue Water Bridge as described in Fisheries Order 200, and 3) “MICH”in Lake Erie was modified to end at the Lake Erie/Detroit River boundary as described in the 2016-2017 Michigan Fishing Guide. Note that all districts consist of whole or clippped (as described above) 10-minute grids except for Lake Erie which consists of whole aggregated 10-minute grids and two clipped (as described above) 5-minute grids (le_602 and le_603). Also note that statistical district boundaries are almost identical to those of the lake trout management units (where they exist) as described in FO-200.GIS layer last updated 10/02/2019.

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.

Lakes from the 1:24,000 National Hydrography Dataset (NHD) were used to depict the Type A-F and Special Type inland lake fishing regulations for trout and salmon. Lake features from the NHD were altered to fit the extent of the regulations described in FO 200. Except for lakes in the Michigan-Wisconsin Boundary Waters and Sylvania Wilderness Area, any other inland lake not classified by type is subject to regulations as described on page 38 of the Michigan Fishing Guide. See pp. 24-25 and 26 for Michigan-Wisconsin Boundary Waters and Sylvania Wilderness Area regulations, respectively. Note that this GIS layer only shows lakes that are classified by type; this layer does not include any lakes that are not classified by type. Every lake in this layer has a regulation type and a designation status. Regulation type 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 combined regulation type and designation status is indicated in the RegTypeDes field. Each regulation type is associated with specific rules for the length of the fishing and possession seasons, minimum size limits, daily possession limits, and tackle type. See FO 200 and the Michigan Fishing Guide for more details about the individual regulation types. Regulation types are as follows: A – Type A Trout Lake; B - Type B Trout Lake; C - Type C Trout Lake; D - Type D Trout Lake; E – Type E Trout Lake; F – Type F Trout Lake; Special - Special Type Trout Lake. Designation status is either designated or non-designated. Designated trout lakes are inland lakes containing a significant population of trout or salmon, as identified by the State of Michigan. Designated trout lakes are protected from certain activities, see the Michigan Fishing Guide or FO 200 for more details. All Type A and Type D lakes are designated trout lakes. All other trout lakes types (Type B, C, E, F, and Special) are non-designated lakes. GIS layer last updated 11/13/2023. Metadata record last updated 3/21/2024.
