Book excerpt: 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).

This book was released on 1974 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

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.

This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Marine Fisheries Service (NMFS), Endangered Species Act, Biological Opinion issued March 2, 1995, require the US Army Corps of Engineers to develop an emergency auxiliary water supply (EAWS) system for all adult fishways where determined to be necessary in coordination with NMFS A reconnaissance level technical report (Lower Snake River, Adult Ladder Systems, Emergency Auxiliary Water Supply (Phase I - Technical Report) prepared in 1995, identified several alternative methods of providing emergency auxiliary water supply for each of the adult fishway systems at each of the four lower Snake River locks and dams to address the Biological Opinion requirement. This Emergency Auxiliary Water Supply, Phase II - Technical Report continues to evaluate the Phase I report alternatives for the Little Goose and Lower Granite Lock and Dams at a greater level of detail. The objectives of this Phase II report are to evaluate, in greater detail, the alternatives previously identified in Phase I report and recommend a selected alternative for providing EAW supplies for each of the adult fishway systems at Little Goose and Lower Granite. This Phase Ii report identifies a construction cost estimate, including engineering and design, supervision and administrative costs and presents a proposed schedule for completing the design and construction of the recommended alternatives for each dam.
