Center for Whale Research Southern Resident Orca community population chart
The typical range of the Southern Resident orca community encompasses the entire inland waterways of Puget Sound, the San Juan Islands, and Georgia Strait in Canadian waters, a vast river-fed estuary known as the Salish Sea. They are known to travel at least 300 miles up and down the coasts of Washington to the south, and along Vancouver Island to the north. It is not known how far offshore into the Pacific Ocean they may travel. They usually swim from 75 to 100 miles every 24 hours.
