The Oregon State University Libraries has created this wonderful collection of 1,000 different images taken between 1934 and 1945 that document 390 streams in the Columbia River Basin. The photographs were taken by U.S. Bureau of Fisheries researchers who were interested in the spawning and rearing habitats for spring Chinook salmon. Visitors can use the clickable map on the homepage to move around through the images, which cover areas like the Puget Sound, the Clearwater region of Idaho, and the Willamette River Valley in Oregon. Each of these separate maps has a finer level of detail, and visitors can even click on various tributaries to look for detailed images. Visitors can use the keyword search, or the geographic search, which allows them to scroll around via major river basins. The site also contains technical reports on the salmon's spawning patterns created as part of this long-term project.
