Find a boat launch near where you want to go

Enter a Michigan city, bay, lake, river or harbor. The finder locates that destination, then ranks source-backed launch choices by distance. Michigan DNR records remain the primary inventory; carefully verified municipal launches can fill documented public-data gaps without inventing pins.

The destination marker comes from OpenStreetMap/Nominatim geocoding. Green pins are source-qualified DNR records; amber pins are DNR records with facility review in progress; violet pins are separately source-qualified municipal supplements. Every Directions link uses the coordinate documented for that launch record. Geocoding © OpenStreetMap contributors.

How launch trust works

Michigan DNR remains the primary inventory. A DNR Great Lakes-access record with a stable source ID and published coordinates can appear in two states, while a documented public-data gap can be filled only through a separately sourced municipal record.

  • Source-qualified DNR: open record with no facility-review flag.
  • DNR review in progress: official open DNR record, shown amber while ramp, parking, fee and hours metadata remain provisional.
  • Municipal source-qualified: the owner/operator establishes the launch and independent location evidence supports the mapped motor-ramp point. It is shown violet and never mislabeled as DNR.

DNR records marked Review Needed, reference-only records and unknown future review states stay withheld. Michigan DNR boating resources · DNR source layer

What the ranking means

The list is ranked by straight-line distance from the destination you searched, not by a guessed “best launch” score. It starts with a 25-mile search area. If fewer than three source-backed choices are available, the radius expands and the page tells you how far it expanded.

  • Missing source fields remain “Not listed”; they are never inferred.
  • Provisional DNR records and municipal supplements cannot satisfy an explicit DNR ramp-class or trailer-parking refinement unless the data model is deliberately upgraded with equivalent authoritative fields.
  • Private marinas and informal road-end ramps are not invented to fill gaps.
  • A primary-source outage is shown separately from a genuine no-match result.
