This book was released on 1976 with total page 42 pages. Available in PDF, EPUB and Kindle. 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).

Available in PDF, EPUB and Kindle. Book excerpt: 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).

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.
