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.

The series documents the various salmonid enhancement and environmental stewardship programs and events the Hoy-Scott Watershed Society (HSWS) organizes and maintains. A significant portion of the series consists of newspaper clippings HSWS maintained about their events and activities reported on in local newspapers. Additionally, it includes Creek and Trail Inspection Reports, feed records, accumulated thermal units, and trough data forms.
