N.Y. Const. art. XV, § 4

Notwithstanding the prohibition of sale, abandonment or other disposition contained in section one of this article, the legislature may authorize by law the lease or transfer to the federal government of the barge canal, consisting of the Erie, Oswego, Champlain, Cayuga and Seneca divisions and the barge canal terminals and facilities for purposes of operation, improvement and inclusion in the national system of inland waterways. Such lease or transfer to the federal government for the purposes specified herein may be made upon such terms and conditions as the legislature may determine with or without compensation to the state. Nothing contained herein shall prevent the legislature from providing annual appropriations for the state’s share, if any, of the cost of operation, maintenance and improvement of the barge canal, the divisions thereof, terminals and facilities in the event of the transfer of the barge canal in whole to the federal government whether by lease or transfer. The legislature, in determining the state’s share of the annual cost of operation, maintenance and improvement of the barge canal, the several divisions, terminals and facilities, shall give consideration and evaluate the benefits derived from the barge canal for purposes of flood control, conservation and utilization of water resources.
