Along rivers or streams, at the foot of hills and mountains with ponds or lakes, and at the mouths of bays and inlets where there are tides. Hydroelectric plants operate on the basis of gravity moving water downward. So the requirement for hydroelectric power is water and a difference in height, altitude or depth. Most Hydroelectric plants are located on rivers and used dams to provide the difference in height. In some cases, hydro plants have been built at the foots of hills or mountains that had lakes on them at higher levels. If the difference in altitude is sufficient, a small flow and a small power plant can produce an impressive amount of power. It is possible to get hydroelectric power from the movement of water without a dam, and this is done in rivers with sufficient current, but where damming the river would be too destructive to the land or things on the land. It is also done in places with tidal flows that are sufficiently energetic. Micro-hydroelectric sites can even be small streams, if the water flow is sufficiently reliable.
Most hydroelectricity is generated from large dams built across large rivers. A smaller amount comes from turbines in rivers, bays and swift-moving tidal races.
Easier access to trade routes, fresh water, faster transportation, hydroelectric power can be built there, easy access to the ocean,
The first hydroelectric dam in Arkansas was built on the Ouachita River. This dam, known as the Blakely Mountain Dam, was completed in 1952 and is part of the Ouachita Project. It plays a significant role in power generation, flood control, and recreation in the region.
Most rivers around the world produce water with the capability of supporting hydroelectric power generation. We can only appreciate from the Yellow and Blue rivers in China, to the mighty Colorado in the Western United States, the harnessing of water power is in full swing -- either established, recently built, or planned.
Hydel Energy, which means Hydro- Electric energy, i.e., electricity produced with help of water.
You have just described a hydroelectric power system.
A dam is typically built to contain the flow of water. Dams are structures built across rivers or waterways to control and regulate the water flow, store water for various purposes, and generate hydroelectric power.
