Pacific Northwest Stream Survey Collection, 1931-1950

The collection includes documents outlining factors affecting salmon spawning in creeks and rivers such as pool grade, bottom composition, and artificial obstructions. The research data consists of handwritten notes and narrative descriptions in files and on 5x8 index cards. The photographs consist of black and white prints and negatives of the creeks and rivers featured in the survey and are stored in a card file box and a file drawer. There are also two scrapbooks of photographs with images of the rivers and creeks featured in the survey, the researchers who worked on the study, and salmon management efforts at dams and hatcheries in the region. The reports, published in seven parts from 1948 to 1950, summarize the data gathered in the survey. Also included in the collection is a map of Keswick Dam which documents migratory fish controls at the dam.
