Sure you could put Niagara Falls in a dam, but it wouldn't be pretty.
They went through a lot of effort to get hydro power from Niagara Falls without ruining the tourist attraction factor. Instead of turning it into a dam, a three square mile reservoir was built and water is diverted from the upper river to this reservoir (mostly) at night. During the day, the dam creates energy by draining the reservoir into the lower river. No part of the power generation system is within a mile of the falls itself.
