Starting June 13, 2025, the National Park Service (NPS) is implementing a new 13-knot vessel speed limit in the eastern part of the Lower Bay whale waters in Glacier Bay. The move is part of the NPS’s ongoing efforts to protect marine life in the park’s waters.
The speed limit is being enforced in the eastern portion of the bay, an area known for its rich marine biodiversity. This area is particularly significant as it is frequented by various whale species, necessitating the need for measures to ensure their safety and preserve their natural habitat.
The NPS has not released further specifics about the enforcement of this new speed limit. However, it is expected that park officials will be monitoring the waters closely to ensure compliance. The new speed limit is a significant step in safeguarding the marine life in Glacier Bay, reflecting the NPS’s commitment to conservation.
