The problems involved in the design of facilities to insure the safe upstream passage of anadromous fish at The Dalles Dam were very complex. Seven hydraulic models, together with full-scale apparatus for testing the effects of rapid decreases of pressure on fish that pass underneath the spillway gates, were used to check the adequacy of designs for the respective elements and to effect revisions if necessary. In addition, full use was made of information gained from operation of Bonneville Dam, McNary Dam, and other major projects in the Pacific Northwest.
