Spillway and Stilling Basin for The Dalles Dam, Columbia River, Oregon and Washington: Hydraulic Model Investigation
The concrete-gravity ogee spillway of The Dalles Dam contains twenty-three 50-ft-wide bays separated by 10-ft-wide crest piers. The crest is designed to pass 2,290,000 cfs under a total head of 61.3 ft; the crest shape is designed for 75 per cent of maximum head or 46.0 ft. A 170-ft-long, hydraulic jump-type stilling basin, with one row of 9-ft-high baffle piers and a 13-ft-high end sill, will dissipate excess energy of spillway flows to and including the project design discharge of 2,290,000 cfs. The hydraulic performance of various elements for the spillway and stilling basin was studied in a 1:36-scale model.
