On March 28, Diana Lind and her husband were motoring their sailboat toward the Ballard Locks when they saw a plume shoot out of the water.

Lind said they slowed down to watch as what she believes was a gray whale did a loop around the area for approximately 20 minutes. She said she thinks there were two whales swimming side by side.

Andrea Takash is the spokesperson for the Army Corps of Engineers, which operates the Locks. She said they don't have any mention of whales in their log books from over the weekend.

Gray whales do occasionally swim near the Locks, though it is rare, Takash said.

The Army Corps of Engineers only knows of one instance where a gray whale made it into the Locks, she said.
