Feb 1, 2018 at 22:52 comment added bendl Let's call it a disagreement about the premise of the question. Can you, to quote OP, "repair and use hydropower plants"? Not if you're talking about the ones that currently exist. Can you build one from scratch and maintain it? Sure, but I don't think that's what he was asking.
Feb 1, 2018 at 22:12 comment added Mark @bendl, you're not going to be using turbines to drive your generators, you're going to be using waterwheels. Yes, that means about a 90% loss of potential output, but kilowatts of power are plenty for a recovering post-apocalyptic society.

Jan 25, 2018 at 0:51 comment added bendl @klingledion I don't think that you could maintain even a small hydro plant. The main difference between small and large plants is really only the number of turbines. The turbines themselves aren't that different
Jan 25, 2018 at 0:14 comment added kingledion @bendl Well, the question does say 'repair or make your own.' I agree the Hoover dam would be a no-go due to the size of the machinery, but medium sized hydro plants may be feasible, as would making your own.
Jan 24, 2018 at 18:32 comment added bendl I hugely disagree that you could somehow repair a modern hydroelectric dam. I believe you could create your own rudimentary hydroelectric generator and maintain that one, but if a turbine fails a modern hydroelectric plant there is absolutely no way to replace it without a factory and huge team of skilled machinists
