2006 New York Code - Making And Recording Maps.

 
    §  24.  Making  and recording maps. There shall be kept on file in the
  office of the corporation complete maps of every canal now or  hereafter
  to be built on which the boundaries of every parcel of land to which the
  state  shall  have a separate title shall be designated and the names of
  the former  owner  and  date  of  each  title  entered.  All  such  maps
  heretofore  approved  by  the  commissioner  of  transportation  or  the
  corporation, or certified by such commissioner, corporation  or  by  the
  state  engineer  or hereafter approved by the corporation to be correct,
  shall be presumptive evidence of the truth of the facts  therein  stated
  and  of the ownership by the state of the lands therein described. Every
  such map when completed shall be approved and certified to as correct by
  the corporation. 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.  Any
  such  maps  filed  in  the office of the clerk of a county in which such
  lands are located or in the office in such county where conveyances  are
  required  by law to be recorded shall constitute evidence to all persons
  of the state's title to and ownership in 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.
