Buying Land in Mille Lacs County, Minnesota

Zoning and wetlands: a directly county-run program

Mille Lacs County's Zoning Office administers the county's Development Ordinance, effective May 1, 2015, which regulates land uses, where buildings may be located on a parcel, the type and number of animals permitted on a property, and rules for on-site businesses in residentially zoned areas, for unincorporated parts of the county. The county's shoreland provisions apply the standard statewide distance -- generally within 1,000 feet of the ordinary high water mark of a lake -- described on our Minnesota state hub, aiming to manage shoreland and water-surface crowding, prevent pollution, and provide adequate space for sewage treatment systems on shoreland lots. For Wetland Conservation Act purposes, Mille Lacs County's own Environmental Services Office serves as the Local Government Unit, administering wetland determinations directly rather than delegating that role to a separate district -- appeals and disputes, including one involving fill placed in a wetland along a township road within the shoreland overlay of the North Fork Bradbury Brook, a DNR public water, have been handled through this county-run structure.

The 1855 reservation boundary: an unresolved dispute, not settled history

It's worth being precise about which legal dispute actually matters here, because two very different cases share the Mille Lacs Band's name. The 1999 U.S. Supreme Court case Minnesota v. Mille Lacs Band of Chippewa Indians (526 U.S. 172) is the historically famous one, but it concerned the Band's treaty hunting, fishing, and gathering rights under an 1837 treaty covering a much larger ceded territory -- it did not decide the boundaries or continued existence of the Mille Lacs Reservation itself. The dispute genuinely live and unresolved today is different litigation: Mille Lacs Band of Ojibwe v. County of Mille Lacs (and related suits naming the County Sheriff and County Attorney), which asks whether the reservation set aside for the Band under the 1855 treaty -- commonly described as roughly 61,000 acres -- remains intact, or was effectively diminished to a much smaller area, commonly cited by the county at roughly 4,000 acres.

In March 2022, the federal district court issued a 93-page ruling affirming that the 1855 treaty territory retains federal reservation status. The county and its officials appealed. While that appeal was pending, the Minnesota Legislature amended Minnesota Statutes sections 626.90 and 626.93 to remove a prior requirement that the Band enter into a joint-powers agreement with the county before Band tribal police could enforce state law within the reservation, effectively granting the Band law-enforcement jurisdiction across the 1855 boundary by statute rather than by court order. On February 12, 2025, the U.S. Court of Appeals for the Eighth Circuit ruled that this legislative change mooted the county's appeal, remanded the case with instructions to vacate the lower court's decisions, and dismissed the county's, the sheriff's, and the county attorney's appeals as moot. The practical result: the district court's earlier rulings on the reservation boundary were vacated, and the underlying boundary question -- whether the reservation is 61,000 acres or roughly 4,000 -- remains legally open rather than decided, even though the Band's law-enforcement authority within the larger boundary is now on firmer statutory footing.

Layered on top of the boundary dispute, the amount of land actually held in federal trust for the Band's benefit within the historically disputed area is commonly cited at roughly 3,600 to 4,000 acres -- itself a small fraction of the full ~61,000-acre 1855 boundary the Band asserts, and a figure that keeps changing: the State of Minnesota separately enacted legislation to return at least 18 acres of state trust land within the reservation boundary to the Band, and in November 2025 a federal judge dismissed a lawsuit by neighboring Morrison County that had opposed placing more than 3,200 additional acres into federal trust for the Band (a separate, Morrison-County-specific case -- see our dedicated tribal trust land page for that county). None of this should be read as a reason to avoid land in or near the historical Mille Lacs Reservation boundary, but it is a direct, current reason to verify rather than assume, and the dispute is still moving: our dedicated tribal trust land page for this county covers the county's own February 2026 move to reopen the fight and how to check a specific parcel's actual status.
