River flows passed through the spillways of the dams located on the lower Columbia and lower Snake Rivers produce water that is supersaturated with dissolved gases. These high levels of dissolved gases are detrimental to aquatic life. In the 1970's, spillway deflectors were installed on the spillways of several U.S. Army Corps of Engineers' projects (Bonneville, McNary, Lower Monumental, Little Goose, and Lower Granite Dams) to reduce the high levels of total dissolved gas (TDG) produced. However, in 1976, it was decided to postpone the construction of deflectors at Ice Harbor Dam. Key fishery researchers of that time judged that spillway deflectors at Ice Harbor Dam would cause poor hydraulic conditions in the tailrace that would likely delay or block adult fish passage. Also, the severity and frequency of TDG supersaturation downstream of Ice Harbor Dam was expected to be reduced significantly in the near future because of several factors. These factors included: (1) the recent completion of all six powerhouse turbines at Ice Harbor Dam, which would significantly reduce the amount of spill discharge required during periods of high flow; (2) the recently completed Dworshak Dam, having 3 million acre feet of active flood control storage, which would also reduce the amount of spill required at Ice Harbor Dam due to high flows; and (3) the installation of spillway deflectors and the accelerated schedule for turbine installation at the three lower Snake River dams upstream of Ice Harbor Dam, which would reduce the frequency and level of TDG entering the forebay of Ice Harbor Dam in the near future. This reduction of TDG in the forebay was expected to reduce, to some extent, the level of TDG downstream of Ice Harbor Dam as well. Operation of Ice Harbor Dam has changedh-IS)GT*GD,G9>G-* (DES(

Preface : This report is an analysis of the two reports, A Special Report on the Lower Snake River dams, Ice Harbor, Lower Monumental, Little Goose, and Lower Granite, Washington and Idaho, U.S. Departmentof Commerce, National Marine Fisheries Service, U..Department of Interior, Fish and Wildlife Service Bureau of Sport Fisheries and Wildlife, September 1972 and Special Lower Snake River Report for Compensation for Fish and Wildlife Losses Caused by Ice Harbor, Lower Monumental, Little Goose, and Lower Granite Locks and Dam Projects, Washington and Idaho, U.S> Corps of Engineers, Walla Walla, 1973. Subsequent to the agreement to evaluate the above two reports, a third report was made available by the U.S. Corps of Engineers. This report is untitled and can be assumed to be an in-house analysis of the two reports mentioned above. Although not reviewed per se, it was used as a resource document.

This study was conducted to identify methods that have been used in the repair and rehabilitation of concrete dams. Information was obtained through literary searches, discussions with project personnel, and visits to project sites. Each case history includes a background of the project, the deficiency that necessitated repair or rehabilitation, and descriptions of materials and methods used in the repair or rehabilitation. When available, the cost of the repair project and the performance of the repair to date have been included. Case histories included in this report cover a range of deficiencies in concrete structures, including cracking, spalling, erosion, leakage, inadequate PMF capacity, expansion resulting from alkali-aggregate reaction, instability, and insufficient storage capacity.

This manual prescribes guidance for designing hydraulic steel structures (HSS) by load and resistance factor design (LRFD) and guidance for fracture control. Allowable stress design (ASD) guidance is provided as an alternative design procedure or for those structure types where LRFD criteria have yet to be developed. Typical HSS are lock gates, tainter gates, tainter valves, bulkheads and stoplogs, vertical lift gates, components of hydroelectric and pumping plants, and miscellaneous structures such as lock wall accessories, local flood protection gates, and outlet works gates. HSS may be subject to submergence, wave action, hydraulic hammer, cavitation, impact, corrosion, and severe climatic conditions.
