SYNOPSISThe Long Lake - Crater Lake Division of the Snettisham HydroelectricProject was authorized for construction by Congress in 1961. Volume 1 OfDesign Memorandum No. 26, Main Report, summarizes the post-authorizationstudies conducted to date for the Crater Lake phase, and presents therecommended feature design developed as a result of those studies.The feature design level studies included agency and environmentalcoordination, geotechnical investigations, computer modelling of thepower conduit and its appurtenances, design analyses, a detailed quantitytakeoff and cost estimate, and preparation of feature level drawings.The next level of effort will be preparation of plans and specifications,during which the design of the features will be refined and detailed.The technlcal appendices contained herein present the geotechnical datafrom the pertinent explorations, as well as sample calculations fortunnel support; the design criteria, methodology, constraints, andcalculations for the hydraulic design of all features of this designmemorandum; and the theory for penstock design. This informationsupplements the general overview presented in the Main Report.
