In some ways the Grants Pass Project or more specifically Savage Rapids Dam, the primary project feature is highly unique. Originally built in 1921 by the Grants Pass Irrigation District and rehabilitated by the United States Bureau of Reclamation in the 1940s, Savage Rapids Dam included fish ladders to aid migration and a fish screen structure to keep fry out of the turbine and pump intakes. At the time of the dams construction the issue of fish in the Pacific Northwest did not receive much attention or consideration, making inclusion of a fish screen structure and fish ladders all the more worthy of note. Fish ladders were left off of Grand Coulee Dam in the 1930s due to economic and technical considerations, though they were included on Bonneville built during the same time period. Unfortunately the fish screen structure proved ineffective and was removed after a single irrigation season. Reclamation installed a new fish screen structure after rehabilitating the dam. On the other hand, the original fish ladders continue to operate effectively. While not the focus of the project, these fish friendly features, primarily because of their early date of construction, are what sets the project apart and makes it distinctive. The Grants Pass Irrigation District must be commended for their foresight.
