[NESC, Table 232-3, p. 104] Reference Heights (Change) Change Footnote 3 to read:
3For controlled impoundments, the surface area and corresponding clearances shall be based upon the design high water mark. For other waters, the surface area and clearances shall be based on the ordinary high water mark. The clearance over rivers, streams, and canals shall be based upon the largest surface area of any 1.6-km-long (1 mi) segment which includes the crossing. The clearance over a canal, river or stream normally providing access for sailboats to a larger body of water shall be the same as that required for the larger body of water.
