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 fonds consists of two scrapbooks and one wooden name plate. The scrapbooks were put together by Dr. Thomas G. Caunt, who worked at Crease Clinic and the Provincial Mental Hospital, Essondale, starting in 1935. He created the scrapbooks for his son and daughter as a record of his employment.

The scrapbooks detail significant moments of Caunt's medical career and personal life during 1934–1968, as well as various events at Essondale Hospital, including the installation of the BC Tel telephone exchange. A significant portion of the scrapbook documents the trips Caunt took in 1949-1950 to move geriatric patients to the new Homes for the Aged in Vernon (Dellview) and Terrace (Skeenaview).

The file contains a scrapbook created by Caunt for his daughter detailing significant moments of his medical career and personal life during 1934–1968. Photographs and newspaper clippings document aspects of Caunt and his wife Lucy's life at the doctor's residences and hospital buildings at Essondale; trips to Stanley Park; a celebration of the 1934 School of Psychiatric Nursing class with doctors and staff held at Dr. Arthur Crease's summer house in Ocean Park, Surrey.

It also depicts various events at Essondale Hospital including the installation of the Hospital's first television, the certification of Crease clinic by the American Psychiatric Association, occupational therapy displays, the installation of a new BC Tel telephone exchange, Christmas parties, retirements, events at Pennington Hall, and the opening of the Industrial Therapy Building. It also documents an event Caunt attended at the Chateau Frontenac in Quebec City held by the Canadian Psychiatric Association and events held at the Empress Hotel in Victoria.

A significant portion of the scrapbook documents the trips Caunt took in 1949-1950 to move geriatric patients to the new Homes for the Aged in Vernon (Dellview) and Terrace (Skeenaview).
