The roots of the Squamish Watershed Society date back to 1993 when a group of people interested in protecting the integrity of the Squamish River Watershed formed the Squamish River Watershed Committee. One of the first projects this Committee embarked on was to study the water quality of the Cheakamus River.
From 1995 to 1998, under the FRBC Watershed Restoration Program (WRP), the Watershed Committee conducted environmental assessments on all of the major watercourses draining into the Squamish River Watershed and the Lillooet River Watershed, identifyied key restoration sites, and conducting in-stream restoration work. In 1998 the organization officially became the Squamish River Watershed Society and was incorporated under the Societies Act of British Columbia.
As a registered non-profit the SRWS successfully applied to participate in the Habitat Conservation Restoration Program which was run through DFO and enabled groups to provide Stewardship Coordinator support to their regions. The SRWS partnered with the Lillooet River Watersheds Council and two Stewardship Coordinator positions were formed to respectively manage the Squamish Watershed and the Lillooet Watershed. This program ran from 2000 - 2003.
From 1999 - 2003 the SRWS was heavily involved with Fisheries Renewal BC (FsRBC) a provincially established organization whose focus was to restore provincially significant fisheries. During that 5 year time period the SRWS was able to administer over 250 projects throughout the Sea to Sky Corridor from Porteau Cove north to D'Arcy.
The SRWS continues to provide the structure to fund watershed related projects, and networking out to provide opportunities for citizens, policy makers, resources users, First Nations, organizations, and interested parties to exchange technical/science based information on issues concerning the watershed.
In 2011 the SRWS became a Registered Charitable organization.
