Great Lakes High Resolution Shorelines

The following outlines the deviations in this dataset from the NHD 1:24,000 open water polygons: NHD 1:24,000 data did not exist for the Canadian side of Lake Huron at time of completion. For this shoreline, the summarized NHN 1:20,000 shoreline was used from the synchronized Watershed Boundary Dataset (NHN data is available in ~50 work units for the Great Lakes and would have been time consuming to process). The NHN shoreline included in the WBD did not cover the St. Marys River, so a shoreline layer provided by the Ontario Ministry of Natural Resources (OMNR) that was created from the Ontario Hydro Network (OHN) was used. Islands for the St. Marys River and some larger islands in Lake Huron were added from the NHN. A small number of islands that were notably missing were digitized and added to the Lake Michigan layer at the 1:24,000 scale. A set of EPA bays was used to add additional, prominent bays and some river mouths to the Great Lakes shoreline basin wide. Source data download dates: National Hydrography Dataset 1:24,000 (1/13/2013); Watershed Boundary Dataset (acquired 1/7/13 from the USGS); NHN (downloaded 1/23/2013); OHN Shoreline (acquired 12/16/2013 from OMNR).
Great Lakes 10-minute by 10-minute statistical grid cells clipped to shoreline

Note, this version of 10-minute by 10-minute grid cells is clipped to the Great Lakes NHDPlus high resolution shoreline where possible. After the union of the Lake Huron and 10 min by 10 min grid coverages, some of the resulting polygons were unioned and nearly all were assigned unique ID numbers as to correpond to the generally accepted 10 min grid definition used by the fishery community. This attribute is found under the field titled "Grid10min." For example maps containing said generally accepted grid definitions, see for example: <"Status of the Fishery Resource - 1989"; A Report by the Technical Fisheries Review Committee on the Assessment of Major Fish Stocks in those Waters of the Upper Great Lakes Ceded in the Treaty of 1836; U.S. Fish and Wildlife Service, Michigan Department of Natural Resources, Chippewa/Ottawa Treaty Fishery Management Authority; Appendix Figure B1.2>. Additional attributes include which Whitefish Management Unit "Wfm_units" and Statistical District "Stat_dist" each 10 minute by 10 minute grid belongs to (as defined by the State of Michigan Department of Natural Resources Fisheries Division) and "Area" in square meters (since meters are the map units of Michigan GeoRef), "Perimeter" in meters, and "Hectares" which were all calculated with the ArcView Xtools Meters/Hectares extension (XtoolsMH.avx). For quality information regarding the shoreline, please refer to the associated metadata cited previously. After merging the shoreline pieces there were two known gaps on the Michigan shore (most likely near the intersection of counties). These were sealed by graphically adding arcs to fill the gap (so that polygons that would not "leak out" could be created). There is no guarantee regarding the accuracy of this editing. The two edits were done at approximately: -83.32 lon, 44.50 lat; -84.22 lon, 46.00 lat. The Mackinac Bridge between the Michigan lower peninsula and Michigan upper peninsula was not included with the NOAA shoreline data that was merged. It was also added graphically, extending from approximately -84.73 lon, 45.79 lat to -84.72, 45.85. There is no gurantee regarding the accuracy of this editing. The has been a reduction of detail from the original shoreline data and grid during editing within ArcInfo/ArcView due to tolerances/snapping/etc. which would be evident upon comparison of this coverage with the two original coverages. The original grid coverage was created in ArcInfo using the Generate command - Fishnet option and was "straight" prior to union. After union of the two coverages, close inspection of some of the grid polygon border-arcs will reveal slight shifts in their "straightness". There has been no attempt to remedy said flaw. It is believed that the overall accuracy is within reason for many fishery applications. Suggestions for fundamental edits to this coverage should be directed to the originator.
Great Lakes Substrate Polygons

Input datasets were compiled by many sources over years ranging from 1968-present. The majority of sources are published journal articles with maps that were digitized. Lake Erie Habitat Task Group data was collected using side scan sonar and proofed with grab samples and underwater video. The shoreline material was extended from the shoreline to the nearshore areas (0 - 30 m of depth) areas of all the Great Lakes except Erie. The shoreline material information is from the the U.S. Army Corps of Engineers (2012) and the shoreline classification from Environment Canada Environmental Sensitivity Atlas (1990s). The shoreline material classification was extended to areas deeper than 30 m for missing data locations in northern Lake Superior. The Euclidean Allocation Tool, part of the Spatial Analyst Extension, was used to extend the shoreline material line feature class values into the nearshore and missing data areas.

Regulations: Tribal commercial fishing by any method other than trap nets shall be prohibited except fishing for chubs with small mesh gill nets or small mesh trap nets. Trap net fishing in this zone shall be open only to Bay Mills and Sault Tribe trap net fishers. A total of four (4) trap net operations shall initially be authorized for this zone. Each trap net operation will be limited to twelve (12) trap nets within the zone. Additional operations may be authorized in the future by CORA based on data collected in previous years. Maps for general reference only: refer to text of Consent Decree 2000 for exact locations and provisions. Created a new point shapefile in ArcGIS 8.1. A point was located on the USGS Alpena county 1:24,000 DRG as outlined in the Consent Decree 2000 documentation. The point was generated at the mouth of the Thunder Bay River. We then created a new polygon shapefile in ArcGIS 8.1. The new pollygon layer was created using the snapping tool in ArcMap. Starting form the above point location and heading in a clockwise direction snapping to the vertices (as outlined in the Consent Decree 2000 documentation) of the MDNR (University of Michigan) Statistical Grid layer, extending the polygon boundaries beyond the US Department of Commerce (Bureau of the Census, Geography Division) county census (1995) layer, and finishing the sketch at the starting point. The new polygon feature was then commbined with the US Department of Commerce (Bureau of the Census, Geography Division) county census (1995) layer using the union tool from the geoprocessing wizard in Arc Map. The desired features were then selected, exported as a new shapefile, and reprojected from Michigan georef to Decimal Degrees to create the final Southern Lake Huron Trap Net Zone layer.

Rogers City Harbor Closure restricted commercial fishing zone

The area within two (2) miles of the break walls at Rogers City. Restrictions: Harbor closure shall apply. Created a new point shapefile in ArcGIS 8.1. A point was located on the USGS Presque Isle county 1:24,000 DRG as outlined in the Consent Decree 2000 documentation. The point was generated on the nautical light located at the southeast end of the breakwall. A two mile buffer was then generated from the point shapefile using the buffer wizard tool in Arc Map. This buffered point location was then intersected with the National Oceanic and Atmoshperic Administration - Great Lakes Environmental Research Laboratory (NOAA - GLERL) shoreline layer using the intersecting tool from the geoprocessing wizard in Arc Map to create the final Rogers City Harbor Closure layer. The desired features were then reprojected from Michigan georef to Decimal Degrees to create the final Northern Lake Huron Inter- Tribal Fishing Zone layer.
