§ 3. All boats navigating the canals and the owners and masters

thereof, shall be subject to such laws and regulations as have been or

may hereafter be enacted concerning the navigation of the canals. The

legislature shall annually make provision for the expenses of the

superintendence and repairs of the canals, and may provide for the

improvement of the canals in such manner as shall be provided by law

notwithstanding the creation of a special revenue fund as provided in

this section. All contracts for work or materials on any canal shall be

made with the persons who shall offer to do or provide the same at the

lowest responsible price, with adequate security for their performance

as provided by law.

All funds that may be derived from any sale or other disposition of

any barge canal lands, barge canal terminals, barge canal terminal lands

or other canal lands and appertaining structures and any other funds

collected for the use of the canals or canal lands shall be paid into a

special revenue fund of the treasury. Such funds shall only be expended

for the maintenance, construction, reconstruction, development or

promotion of the canal, canal lands, or lands adjacent to the canal as

provided by law.
