We began in 1994 as the Chums of Maxwelton Salmon Adventure - a group of teachers joined with others to provide outdoor Environmental Education for elementary school students in the South Whidbey School District. MSA quickly grew to working with the community and other agencies to Restore Salmon runs to the Maxwelton Watershed on Whidbey Island, and encouraged Watershed Stewardship through habitat restoration and individual actions.

Our mission expanded in 2006 and we became Whidbey Watershed Stewards, recognizing that we want to promote the health and vitality of all of South Whidbey's watersheds and nearshore for the people and environment of Puget Sound. Whidbey Watershed Stewards promotes nearshore and watershed health by linking water, land, wildlife and people on Whidbey Island through education, research, and restoration.
