John Day Dam, Columbia River, Oregon and Washington; Hydraulic Model Investigations
Excavation requirements, adequacy of cofferdam and diversion plans, project layout, structures designs, and proposed methods for operation of the John Day Project were investigated in a 1:80-scale general model. Water-surface data from the general model were used to regulate a 1:25-scale model in which satisfactory designs for the skeleton powerhouse units were developed. The general model was verified with natural water-surface elevations (before construction of The Dalles Dam) and with similar data after The Dalles pool was filled. Agreement between model and prototype flow patterns and water-surface elevations was satisfactory for both conditions.
