Washington State Parks and the Nisqually Indian Tribe jointly manage the park, ensuring that the park respects the Nisqually people’s cultural and spiritual connections to the land. The Nisqually people lived where “the three rivers come together for thousands of years.” The Nisqually people were fishermen who lived off the rich river bounty and sustained life for their homes and environment. They were the traditional landowners before being forced to cede their lands and move to a reservation outside Olympia.
