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 collection consists of assorted maps of the Coquitlam area that have been donated or transferred to the City of Coquitlam Archives and are not part of a specific fonds or collection.

The collection consists largely of research materials and notes created in the preparation of Boire's book "With Hearts and Minds" published in 2016. The remainder of the collection consists of materials collected by Boire from Caisse Populaire Maillardville Credit Union, as well as accumulated material pertaining to Boire’s involvement in several community initiatives, such as the Maillardville Residents' Association, Maillardville revitalization and planning, and Place Maillardville.

Materials include correspondence, photographs, administrative records, interviews, reports, handwritten notes, clippings, advertising and professional materials, newsletters, research materials, prints, postcards, ephemera, a map, embossing seals, a lid from a glass milk bottle, and other documents. The collection also includes a manuscript copy of “With Hearts and Minds”.

The file consists of aerial photographs of the Coquitlam area organized by flight path.
