- Locks_on_the_C&O_Canal abstract "The Locks on the C&O Canal, located in Maryland, West Virginia, and Washington, D.C. of the United States, were numbered from 1 to 75 with two locks, 63⅓ and 64⅔, having fractional numbers and no lock 65. There is also a lock at the downstream end of the canal in Washington, DC where Rock Creek flows into the Potomac River which is sometimes called Lock 0 or the Tidewater Lock.The canal had several kinds of locks: Lift locks, River locks, and Guard locks (also called Inlet locks).The final locks (70-75) had been completed earlier than 1842, before locks 62 and 66. It was found that the level of the canal between locks 62 and 66 could be raised in three steps instead of four. So the additional locks through there were numbered 1⅓ steps apart (62, 63⅓, 64⅔ and 66) so that the other locks, already completed, did not have to be renumbered.While the National Park Service FAQ states that it takes about 10 minutes for a boat to lock through, experiments done in the 1830s show that it was possible for a boat to go through in 2½ minutes, although 3 minutes was their average.".
