If the water were drawn off at a height of 2,100 feet or 60 feet below the flow line, the available capacity of the reservoir would be 27,810 acre-feet. On these assumptions and taking the run off above computed, the following table has been prepared showing how we should have fared between the years 1866 and 1890.
