Summary
The Grand Traverse Band of Ottawa and Chippewa Indians (GTB) is a present-day sovereign tribal government whose official history dates federal recognition to 1980. Its public history describes treaty-grounded sovereignty and a service area extending across six Michigan counties.
GTB’s current Great Lakes Management program provides a direct Beaver Island connection: the tribe says it operates a commercial marina on Beaver Island, licenses and monitors commercial fishing, conducts lake assessments, and maintains fishery data. This is present-day institutional evidence, not proof that GTB and the treaty-era Beaver Island Band are the same legal entity.
Open questions
- What tribal-authored and legal sources define GTB’’s specific relationship to Beaver Island and to the 1836 and 1855 treaties?
- Which current fishery, marina, and cultural-resource records can be cited at a useful level without exposing protected information?
- How should GTB and LTBB relationships be represented where their treaty rights or service areas overlap?
