History of Lock 33
The lock was built as a double Enlarged Erie in the late 1830's--say 1838 - 1840. It was definitely opened for navigation and brought into use at the opening of navigation in 1840. Therefore it had to be built in the few preceding years. Since Clinton's Ditch ran on a diagonal South of the lock they could work on this lock "in the dry" without concern about traffic and navigation on the old canal. My guess is that the lock probably took only a year or two to built that is why I say 1838-1840. Perhaps construction started earlier (my hunch is not) but I can't verify that at this time. If construction did start earlier it could have begun NO earlier than 1836 as that is when construction of the Enlarged Erie began.
It was lengthened at the head of the berme side instead of the foot probably because Lock 33 is located at the end of a curve and lengthening it at the foot would make the lower end of the lock stick out into the curve taking away from the arc of the bend rendering it sharper and for double headers this could be a big problem. Here again that is my interpretation as I have not found that in writing as of this message. There must have been a good reason for lengthening at the head because it is more difficult and expensive to lengthen at the head than the foot because of the greater excavation required into the upstream canal bed as opposed to the downstream end where all that is required is excavation for footings. Compare bids for Locks 32 and 33.
Perhaps the remains of that waste weir is still there--so perhaps when you get a chance please check the berme bank just West of the lock to see if you can find it.
There was another waste weir on the towpath side about 2,400 feet ( 1/2 mile perhaps 3/4 mile) West of Lock 33. I think perhaps that has been buried under the road or the muck piles from the 1930's deepening of the Barge Canal to 14 feet depth. But who knows. Another exploratory hike when you have nothing better to do.
