In the power sites water will always be held at the top level and in the regulating reservoirs near the top, so that water will be in the reservoir for the low year. A part of this area is already occupied by the stream, so that additional evaporation needs only to be considered. Assuming, roughly, that additional evaporation will take place on 75 per cent of the above maximum areas and assigning values, the following table results: Table No. 8.-Estimated future depletion by evaporation from Reservoirs.
