interpretation and application of this article, nothing authorized
hereunder shall be construed to convey any property rights, either in
real estate or material, or any exclusive privilege; nor authorize any
injury to private property or invasion of private rights or any
infringement of federal, state or local laws or regulations, but shall
express the assent of the state so far as it concerns the public rights
of navigation. Nothing contained in this section shall be construed to
limit, impair or affect the general powers and duties of the canal
corporation relating to canals as set forth in section ten of the canal
law.
