Not really, take a gander at this:

Basically everything in that is a bit of information you need to monitor and understand to ensure one of your turbines doesn't catastrophically explode, which generally leads to other turbines being damaged and the power house being flooded (which renders /everything/ useless) - and that doesn't even cover the knowledge required to clean and maintain the turbines themselves, or the operation of the reservoir itself (debris buildup and flooding are two major issues).
It's also likely there will already be a military unit and engineers stationed in a hydroelectric dam; the military will need the power to keep their bases running (even if they have their own generators it'll still be more limited in fuel than a hydroelectric dam, wind farm, or solar farm), keep civilian routes of communications open, and make taking back zombie-infested cities (if possible) easier if operations can run 24/7 rather than whenever the sun is up.
You'll probably be able to find refuge in that situation, but at the same time the Law of Zombie Outbreak pretty much demands such a situation means an overwhelming horde of zombies will be knocking at the doorstep at any moment.
