Titan AC - What's next for Titan? Hydroelectric power?

Now we know what the surface of Titan looks like, its a world with oceans,
lakes and rivers of something. How about a follow on mission? Clearly its a
unique body. Perhaps there is a Case for Titan. Humans could settle Titan, and
I thought about a unique form of power to power the settlement. How about a
hydroelectric dam? There are lakes and rivers of hydrocarbons, what if we built
a dam in front of one of those rivers and created an artificial hydrocarbon
resevoir behind it. The hydrocarbon lake would build up behind it and create
pressure on the dam. The pressure could turn a turbine and create electricity
for a manned base on Titan. Naturally some of that electricity can be used to
heat the base, and create oxygen to breath and water to drink from the surface
ice. Titan is the only other world in the Solar System besides Earth where you
could build a hydroelectric dam.
