This book was released on 1973 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modifications of the flow control sections and counting stations of the Bradford Island and Washington Shore fish ladders at Bonneville Dam were necessary to accommodate rapid pool changes which will result from fluctuating discharges caused by power peaking at hydroelectric projects upstream. Fishway operation for the extreme flood control pool range from elev 70.0 to elev 82.5 (feet above mean sea level) was considered. The normal range for design was between elev 72.0 and 80.0. A portion of the forebay, the exit control section, the counting station, the supply channel for auxiliary water, and typical sections of each ladder were studied in a 1:14-scale model.

This book was released on 1984 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prototype operation of the originally constructed fish ladders at John Day Dam revealed the need for ladder modifications to improve fish passage. A 1:10-scale model was used to evaluate the design modifications for both the north-and south-shore ladders. Improvements were desired in the flow-regulating sections and at the fish counting station for both fish ladders. The model was instrumental in developing a successful modification to the Hell's Gate slot-orifice type regulating section. The modification consisted of a slot-only design having a maximum head drop of approximately 6 inches. A vertical counting station was developed for the north-shore ladder. Successful operation in the prototype has verified the effectiveness of the design.

This book was released on 1968 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Facilities for passing fish upstream over John Day Dam include a powerhouse collection system with fishway entrances at each end and along the downstream face of the powerhouse, and a 24-ft-wide fish ladder with 1-on-10 slope on both sides of the river. The north fish ladder (except entrance section) and a portion of ladder adjacent to the south fish counting station were studied in a 1:10-scale model. A group of four typical diffusion chambers in each ladder was reproduced in a 1:8-scale model. Fishway weirs with 6-ft-long overflow crests at each end of a 12-ft-long nonoverflow section, upstream fins, and 18- by 18-in. orifices at the floor were adopted. Orifice sizes in the regulating sections were adjusted to control discharge and head drops between 19 nonoverflow bulkheads for an 11-ft range in forebay levels. Sloping floors, baffle beams at a constant elevation, and metering orifices sized to provide 60 cfs each were selected for diffusers in sloping portions of the fish ladders.
