A dam is built across a river to control the flow of water.
A good place for a tidal barrage is somewhere like a river mouth, or a bay that has a narrow opening to the sea. You want a lot of water to come into the collection area at high tide, and then you want to catch it all in as small an area as possible to set up your turbines to harness the power of all the water. The Rance River Power Station in Brittany, France, is the world's first tidal power station. See link below.
No, the Clermont and the Rocket were steam-powered vessels. The Clermont, also known as the North River Steamboat, was a steamboat built by Robert Fulton in 1807. The Rocket was a steam locomotive built by George Stephenson in 1829.

The Susquehanna River is the closest river to Newton, Pennsylvania. It is about 20 miles to the west.
In a run-of-the-river hydroelectric system, electricity is generated using water flowing in a river without significant water storage or dams. This approach minimizes environmental impact but may have variable power output due to fluctuating water levels. In a storage system, water is stored in dams or reservoirs and released as needed to generate electricity, providing better control over power output but with greater environmental impact.
