Pages were scanned at 400 ppi on Fujitsu fi-5650C sheetfed scanner as 8-bit grayscale or 24-bit RGB uncompressed TIFF images. For ContentDM access the images were resampled to 750 pixels wide and 120 dpi and saved as JPEG (level 8) in PhotoShop CS with Unsharp Mask of 100/.3. Foldout pages larger than 11" x 14" were captured using a BetterLight Super 8K-2 digital camera back on a 4x5 view camera (100mm Schneider APO lens). Oversize images were resampled to 1500 pixels wide. Optical Character Recognition (OCR) by ABBYY FineReader 7.0 with manual review. |

Show APPENDIX VI VI-25 20 COLORADO RIVER STORAGE PROJECT 2. Recorded flow of the Colorado River at Grand Canvon. 3. The computed theoretical inflow to Lake Mead will be the sum of 1+2. Arrangements would be made to obtain end-of-month contents for the month for each of the upstream filling reservoirs immediately after the end of the month. Records of discharge of the Colorado River at Grand Canvon are available under the present operating methods, so no change would be required to obtain that record. LAKE MEAD OPERATION 1. The theoretical inflow to Lake Mead would be as computed above. 2. Forecasts of Lake Mead inflow would be made exactly as they are mode under present operating criteria, and the release from Hoover Dam to meet predetermined requirements based on (a) flood control under regulations being used prior to Glen Canyon; (6) irrigation orders and predetermined levels of Lake Mohave; (c) energy production schedule as computed from June 1 forecast each year with the firm schedule of generation used if the resulting end-of-Deecmber content will stay above 17 million acre-feet. In years of less than firm, as indicated by the theoretical study, that percentage of firm will be generated that will permit the end-of-December content to be 17 million acre-feet or downstream water requirements will be released from Hoover Dam, whichever is the greater. Releases to meet downstream requirements will be made each year regardless of resulting reservoir elevations. The committee on integration and interests of the upper basin will be consulted at the beginning of each operating year, and the proposed theoretical study will be discussed. Actual programs of operation of Hoover Dam will be determined at the regularly scheduled integration committee meetings. It will be necessary to make some assumptions with respect to distribution of firm energy during a theoretical operation year as actual firm will not usually be attained under the actual operating condition. This distribution of firm energy for the theoretical study will be determined as that which would be produced by the release of water to meet the current estimate of downstream requirements during each of the months of June through September and March through May, and the balance distributed to the months of October through February in a pattern similar to that adopted by the regular integration committee, or a river operation committee if established, for the actual operation of Hoover powerplant during that year of operation. These computations on a monthly basis will be carried on concurrently with the actual recorded operation of Lake Mead and Hoover Dam to compute the deficiency in Hoover firm energy. Attached is a set of computation forms to be used in the determination of the deficiency in firm energy deliveries at Hoover powerplant. The forms will be kept current each month by the Bureau of Reclamation, and copies will be furnished to all interested parties as soon as possible after the end of each month. |
