N.Y. Canal Law § 25: Making and recording of "Blue Line" maps

§ 25. Making and recording of "Blue Line" maps. The commissioner of

transportation shall cause the preparation of maps of the Erie, Oswego,

Champlain and the Cayuga and Seneca canals as they existed prior to and

independent of lands appropriated for barge canal purposes and of all

lands belonging to the state adjacent thereto or connected therewith,

and there shall be designated on such maps the boundaries of the lands

to which the state holds title, and so far as possible the names of the

owners of the adjoining lands. Every map when completed shall be

approved and certified to as correct by the commissioner of

transportation and be certified to as correct by the chief engineer. The

original of said map shall be filed in the office of the corporation and

copies thereof, duly signed and certified as aforesaid, shall be filed

in the office of the department of state. Each of said maps so filed

shall be regarded as an original copy. A blue or white print copy of

such map or portion of such map or maps as related or applies to any

particular county of the state shall be transmitted to and filed in the

office of the clerk of such county, or in the office in such county

wherein conveyances are required by law to be recorded and such filing

shall constitute a notice to all persons of the state's title to and

ownership of said lands. A transcript of such maps certified as correct

by the officer with whom such map or maps shall be filed shall be

received as presumptive evidence of the state's title to the canal lands

as of the date designated on such maps in all judicial or legal

proceedings.
