The monthly flows of a stream over the period of the driest year on record are shown below [table]. (i) Estimate the maximum possible uniform draw-off from this stream and determine the reservoir capacity to achieve the uniform draw-off and the minimum initial storage to maintain the demand. (ii) If the reservoir has only a total capacity of 8×10⁶ m³ with an initial storage of 4×10⁶ m³, determine (a) the maximum possible uniform draw-off and (b) the spillage. [7+3+2]
