Lake Ontario Shipwreck Anchoring Ban Delayed Until September 2028

NOAA has delayed the effective date of Lake Ontario National Marine Sanctuary’s prohibition on grappling into or anchoring on shipwreck sites until September 21, 2028. The final rule took effect July 15, replacing the previous July 21, 2026 start date for that specific prohibition.

The postponement is intended to preserve public access while NOAA builds an alternative mooring system. Sanctuary managers have identified 16 shipwrecks for the initial installation effort, obtained required state and federal permits and awarded contracts for mooring components. Installation was originally expected to begin in 2025, but NOAA was unable to secure partner vessel time and must complete the work during Lake Ontario’s summer seasons.

For dive boats, the delay means the sanctuary’s federal provision specifically banning grappling into or anchoring on wreck sites is not yet in force. It does not grant permission to damage a wreck. All other sanctuary protections remain active, including the prohibition on moving, removing, recovering, altering, destroying, possessing or otherwise injuring sanctuary resources. New York law also continues to prohibit wreck damage, including damage caused by anchoring or grappling.

NOAA says the permanent buoys will provide a safer way for divers and boaters to reach priority wrecks without placing hooks or anchors on fragile historic structures. The additional time also allows the sanctuary to develop best-practice guidance and conduct public education before the federal prohibition takes effect.

Divers and operators should therefore treat the delay as a temporary access transition, not an invitation to attach gear to wreckage. Use an installed sanctuary mooring when one is available, keep anchors and grapnels clear of cultural resources, and confirm current site-specific guidance before leaving port.

Lake Ontario’s sanctuary wrecks remain open for responsible diving and snorkeling. The practical change is the date of one federal restriction; the responsibility to avoid contact, disturbance and artifact removal has not changed.
