Glacier Bay National Park and Preserve Superintendent Susan Boudreau announced today that a vessel speed limit of 13 knots through the water will be implemented in lower Glacier Bay to protect numerous humpback whales that have been sighted in this area. This speed restriction will apply to all vessels from 5 AM Tuesday June 18 until further notice. In addition, in lower Glacier Bay whale waters, vessels greater than 18 feet in length are restricted to a mid-channel course or 1 nautical mile offshore.
Whale waters at the mouth of Glacier Bay and around the Marble Islands remain unchanged. Since May 8, a 13 knot vessel speed limit has been in place in Park waters at the mouth of Glacier Bay. In addition, on June 7 a 13 knot vessel speed limit was implemented within 1 nautical mile of North and South Marble Islands. There are no vessel course restrictions in these areas.
As shown on the attached map, lower Glacier Bay whale waters include the waters extending from the mouth of Glacier Bay to a line drawn between the northern tip of Strawberry Island and the northern tip of Lars Island. This boundary is shown on NOAA nautical charts of Glacier Bay. The whale waters at the mouth of Glacier Bay are bounded on the north by an imaginary line between Point Carolus and Point Gustavus, and on the south by the Park boundary in Icy Strait. The eastern boundary is an imaginary line running due south from Point Gustavus to the Park boundary, and the western boundary is an imaginary line running due south to the Park boundary following longitude 136 degrees 05' West. The whale waters around North and South Marble Islands extend from the shoreline of the islands out to 1 nautical mile.
Boaters should proceed cautiously in all areas where whales may be present because whales may surface in unexpected locations, posing a hazard to both the vessel and the whale. Although humpback whales tend to be distributed along the shoreline, boaters should note that whales frequently cross mid-channel as they move between feeding sites. Vessels are prohibited from operating within ¼ nautical mile of a humpback whale in Park waters, including those Park waters outside Glacier Bay proper. In addition, vessel operators positioned within ½ nautical mile of a humpback whale are prohibited from altering their course or speed in a manner that results in decreasing the distance between the whale and the vessel. Speed and course restrictions in whale waters are intended to reduce the disruption of feeding humpback whales and to lower the risk of whale/vessel collisions.
Boaters are advised to verify whale waters designations prior to entering Glacier Bay by telephoning (907) 697-2627 or by contacting KWM20 Bartlett Cove on marine VHF radio. Whale waters restrictions are authorized in Glacier Bay National Park in accordance with Title 36 of the Code of Federal Regulations, Subpart N, 13.1174.
