Rufus Wheeler Peckham, St. Anthony Falls Water-Power Company v…
“ It was proper and in accordance with a wise public policy to grant a privilege to these companies to build dams, etc., as stated in the charters, and to permit them, by virtue of the dams and sluices, to use the water that in fact and from time to time might come down the river, but it cannot be supposed that the legislature meant by any grant of this kind to warrant that for all future time no part of the water that might otherwise naturally flow down the river should ever be used under the authority of the state for any public purpose, without compensating the plaintiffs for that diversion. ”
