The Hoy-Scott Watershed Society fonds consists of the records created and received by the Hoy-Scott Watershed Society and reflects its hatchery operations, salmonid enhancement and environmental stewardship programs, events, and environmental advocacy initiatives in the larger Coquitlam Watershed.

The fonds consists of administrative records, reports, correspondence, event planning files, newspaper clippings, newsletters, publications, plans, a scrapbook, promotional materials, and photographs documenting the activities of the Hoy-Scott Watershed Society and the operations of the Hoy Creek Hatchery in Coquitlam.

The fonds was arranged into four series by the archivist. See the Physical condition and Arrangement note below for more information.
