Rufus Wheeler Peckham, United States v. Bellingham Bay Boom Company…
“ The power of Congress to pass laws for the regulation of the navigation of public rivers, and to prevent any and all obstructions therein, cannot be questioned. When Congress chooses to act, it is not concluded by anything that the states or that individuals by their authority or acquiescence have done, from assuming entire control of the matter, and abating any obstructions that may have been made, and preventing any others from being made except in conformity with such regulations as it may impose. The ultimate power of Congress over the whole subject is undoubted. ”
