Theordinates of required storage are measured on the Hne A B until thepoint G is reached, corresponding to a minimum flow of 1,238 second-feet, the ordinate A-G being equal to the ordinate H-M. Below aminimum flow of 1,238 second-feet the ordinates of required storageare measured from H on the Hne H M. For a minimum flow greater than 2,500 second-feet the ordinatesof required storage are greater than A B and are defined by the slant- 3000. 500 0 20 40 60 80 100 120 2 MINIMUM STORAGE REQUIRED IN BILLION CUBIC FEET ^ Figure 5.—Minimum discharge of West Branch of Penobscot River at MlUinocket for given storage in billion cubic feet. ing lines 2,600, 2,700, etc. It will be noted that the line marked2,571 passes through T> and E, and for minimum flow greater than2,571 the dotted lines radiate from E, corresponding to a time of46 months (March, 1903, to March, 1907), during which water storedprior to March, 1903, will be used. The probable upper hmit of storage is indicated by the averagedischarge at Milhnocket during the period 1901-1909, inclusive, whichwas 3,160 second-feet, or second-feet per square mile of drain-age. It seems best to set the limit somewhat below this figure andtherefore second-feet per square mile of drainage (or about 3,000second-feet at Milhnocket) will be assumed as the limiting quantityof water to be considered in these storage inve
