Maybe not.
The Cascade Locks and Canal which I just clicked on were 90 feet high to deal with a 55 foot [17m] variation on the Columbia River, while the wiki Lock article reports that Portuguese locks on the Douro River have rises of 108 [33m] and 115 feet [35m], while the Irish have a couple of 100 feet [30.5m] locks on the Shannon.
Given another 300 years of improving technology in the Terran Federation, I suspect much higher rises are quite possible.

The problem is not in the construction--the problem is filling and emptying the locks. Large rises require modern pumping. Safehold-tech locks can't be that high.
Why would you need pumps? You need valves and pipes to allow water to flow from the upper level to the lower level in a controlled manner.
