Geneva Gazette
July 17, 1822

We are informed that in consequence of the lowness of the water in this section of the canal, it is to be drawn off the upper levels, beyond Palmyra, and that until the embankment at Mann's Mills is completed, and the waters of the Genesee river let into the, the navigation will not extend farther westward than Palmyra.
