[illegible]possible value in connection with land development , only the amountof water that could be drawn off at a certain fixed level was estimated; This amount Mr. Martin and Mr. O’Shaughnessy figured at125,625 acre feet, or in gallons,-40,933,000,000. Bellow this levelin the large reservoir there are approximately 15.000,000,000gallons more, which makes the total capacity of the large reservoiras above stated, 65,000,000,000. Mr. O’Shaughnessy’s suggestion thatthe project would be tremendously valuable for city supply, led tofurther investigation which brought to light the other reservoirsherein mentioned. The following is a quotation from a report datedJuly 29, 1912, made by Mr. O’Shaughnessy to Wm. H. Crocker of SanFrancisco, concerning the largest reservoir herein referred to:-"As the outlet of reservoir will have an elevation of 300feet above the sea, it would be possible to use this source as anauxiliary supply to Oakland, Berkeley or San Francisco, The waterwould be pure, unpolluted water from the snow shed of the Sierras,and the expense of developing and conveying would not be 60% of manyof the other Sierra schemes.Owing to the fact that reservoirs are situated in the foothillsand that facilities for construction work are of the best, thecost Hetch Hetchy project.The estimates of the capacity of the small reservoirs have beenmade conservatively, and Mr. Martin, the Engineer states that inhis opinion construction work will hardly [illegible] any more expensive pergallon of storage than in the case of the largest reservoir.I would be glad to furnish you with such data as I have at mycommand, but would prefer that an [illegible] engineer, whom you maycare to appoint for the work [illegible]made a complete report.Yours [illegible] truly,[illegible] Burton Harrison06341
