16 U.S.C. § 160a–1 — Boundaries

(a) Lands and waters included; legal description; revision: Except as subsection (b) allows, the park includes the land and water shown on a specific map — "Voyageurs National Park, Proposed Land Transfer & Boundary Adjustment," numbered 172/80,056, dated June 2009 (22 sheets) — kept on file at the National Park Service. Within one year of the state and local governments donating their land within the park, the Secretary must add an exact legal description of the boundary to this map. The Secretary can revise the park's boundary later by publishing a new map or description in the Federal Register, but can never grow the park by more than 1,000 acres through these revisions. (b) Additional revisions; procedures applicable; failure to comply with procedures: (1) The Secretary may also make five specific boundary changes, using the same process as subsection (a): (A) removing about 782 acres in the Neil Point area; (B) adding about 180 acres in the Black Bay Narrows area; (C) adding about 18.45 acres the State of Minnesota owns at the Kabetogama Forestry Station; (D) adding about 120 acres of state-owned land forming a strip along an unimproved road north of Ash River Trail; and (E) — subject to paragraph (2) — removing about 1,000 acres at Black Bay and giving that land to Minnesota. All these changes must match a specific 1981 boundary drawing kept on file at the National Park Service. (2) The Secretary can only remove and convey the Black Bay land in (1)(E) if Minnesota, before or at the same time, does two things: (A) transfers the land described in (1)(C) and (D) to the United States (by lease, easement, or better) — if it's only a lease or easement, Minnesota must convert it to full ownership by June 30, 1987, or that Black Bay land reverts to the park; and (B) signs a recordable agreement promising that: (i) Minnesota has created a wildlife management area on the land it received; (ii) Minnesota has a Secretary-approved plan to manage the waters and state land around Black Bay (including all of Rainy Lake's state-owned parts) to support the park's purposes; (iii) Minnesota won't transfer that land to anyone except the Secretary; and (iv) Minnesota will let the Secretary access that land at reasonable times. (3) If Minnesota ever breaks the material terms of that agreement, the Black Bay land reverts back to the United States as part of the park. This reversion happens automatically once the Secretary delivers notice of the violation to Minnesota — unless Minnesota challenges it in the appropriate U.S. Court of Appeals within 90 days of that notice, in which case the court can issue whatever orders are appropriate.
