of New Hampshire wherein such dam and reservoir would be located, wholly or in part, by reason of acquisition and ownership by the United States of lands, rights or other property for the construction and operation of such flood control dam and reservoir and shall decide whether the flood control benefits to be derived in the signatory states from such flood control dam and reservoir, both by itself and as a unit of a comprehensive flood control plan, justifies, in the opinion of the commission, the assumption by a signatory state of the obligation to make reimbursement lor loss of taxes and for economic losses and damages. Such estimate and decision shall thereafter be reviewed by the commission at five-year intervals until such time as the United States shall have acquired title to the site of such flood control dam, or plans for its construction are abandoned. The commission shall notify the governor, the members of the United States Senate and the members of the United States House of Representatives from each signatory state, and the chief of engineers as to the commission's decision and as to any change in such decision. "On receipt of information from the chief of engineers that any flood control dam and reservoir is to be constructed, reconstructed, altered or used for any purpose in addition to flood control, including those flood control dams and reservoirs heretofore constructed and those specified in Article IV, the commission shall make a separate estimate of the amount of taxes which would be lost to and of economic losses and damages which would occur in political subdivisions of the signatory state wherein such dam and reservoir would be located, Avholly or in part, by reason of acquisition and ownership by the United States of lands, rights or other property for the construction and operation of such dam and reservoir m excess of the estimated amount of taxes which would be lost and of the economic losses and damages which would occur if the dam were constructed and operated for flood control only, and the commission shall decide the extent to which, in its opinion, the signatory states would be justified in making reimbursement for loss of taxes and for economic losses and damages in addition to reimbursement for such dam and reservoir if constructed and used for flood control only.

The commission shall notify the governor, the members of the United States Senate and the members of the United States House of Representatives from each signatory state as to the commission's decision and as to any change in such decision. "Within thirty days after acquisition by the United States of the site of any flood control dam the commission shall proceed to make a final determination of economic losses and damages occasioned by such dam and reservoir. The commission shall not include in such determination either speculative losses and damages or losses and damages for which the United States is liable. "The commission shall compute the share the Commonwealth of Massachusetts shall pay to the State of New Hampshire by multiplying the sum of such losses and damages, as previously determined, by the percentage of flood control benefits which the Commonwealth of Massachusetts receives of the flood control benefits resulting from the dam and reservoir.
