Puget Sound Orca Populations, by Pod
Southern Puget Sound's orca pods have increased in population since 1974.
Date range: 1974-2004
Caption: As a result of strict protection measures in the 1970s, killer whale numbers began to increase until the 1990s. Over the next few years, the population tailed alarmingly downward, mainly in the large L pod. Luckily, since 2000, their numbers have begun to climb once more.
