A 1:10-scale hydraulic model was used to develop designs for the overflow section, weir upstream from the fish counting station, orifice control section, and exit of a 20-ft-wide, 1v on 10H-slope fish ladder for Little Goose Dam. Data from this study were used to design a similar fish ladder for Lower Granite Dam. An improved type of control section with vertical slots and submerged orifices in the bulkheads was developed in the model for use at Lower Granite. This type of control section was installed at both projects. (Author).

Facilities for passing fish upstream over Lower Monumental Dam include a powerhouse collection system and a 16-ft-wide fish ladder on both sides of the river. A straight, 35-pool section of fish ladder and a typical fishway entrance weir were reproduced in a 1:10-scale model. Performance of a pair of typical diffusion chambers was studied in a 1:8-scale model that included portions of the adjacent supply conduit and fish ladder. Fishway weirs of original design, with 5-ft-long overflow crests at each end of a 6-ft-long nonoverflow section, upstream fins, and 18- by 18-in. orifices on the floor, were satisfactory. Discharges of 66.0 and 69.7 cfs produced heads of 10.0 and 12.0 in. on the weirs. With standard orifices in all weirs, heads of 12.2 and 13.4 in. on the first weir below the fish counting station were required to provide the above discharges. (Modified author abstract).

Facilities for passing fish upstream over Ice Harbor Dam include a powerhouse fish collection system, auxiliary water supply systems, and a fish ladder on each side of the river. A 1:10-scale model was used to develop designs for the overflow weir portion, regulatory section, and exit of each fish ladder. Tests of the 24-ft-wide, 1V-on-16H-slope south fish ladder indicated that the tendency for self-induced surges in a straight 41-pool section was reduced by 2-ft-long nonoverflow baffles at each end of the weirs. A satisfactory design of full-length overflow weirs with The Dalles-type crests and 21- by 23-in. orifices was adopted. A regulatory section with staggered 21- by 60-in. orifices in nonoverflow baffles was selected from four alternative designs. (Modified author abstract).
