Hydro comes from the Greek word for water. Hydro-electricity, or hydro-power, is usually generated by turbines in a dam in a river. The dam means that a great body of water builds up in the river valley behind the dam. This is released through the turbines when electricity is needed.
Smaller than dams are barrages across the mouths of rivers which capture water from high tides and release it to generate electricity. Smaller still are turbines in river and tidal streams which do the same thing.

In brief:
Hydro was the first commercial source of power of any size. The uses were understood right away, but there certainly are drawbacks.
They destroy farmland and alter the course of rivers. They must also be located at the discretion of the plant rather than our choosing. Much of our power that we use today is not even used constructively. There is a large portion of our energy that is used in transporting it across the country. The major disadvantage I would put against this form of power would be the land and energy consumed in transporting the power away from the plants. Grid loss is a major issue for energy users.
It is a renewable energy source. Unlike fossil fuels which will eventually run out, hydro power plants do not use up the energy source. It is also not polluting to the environment. They output power at a relatively reliable rate (compared to solar or wind, especially). On the other hand, they drastically affect all ecosystems upstream of the dam, and are much more environmentally destructive than nuclear power plants.
Advantages
Disadvantages
The advantages counterbalance the disadvantages so there aren't disadvantages.
next question
Some disadvantages of hydroelectric power plants include their impact on aquatic ecosystems and fish populations due to changes in water flow, displacement of communities and loss of land due to dam construction, and the potential for reservoir sedimentation to reduce operational efficiency over time. Additionally, hydroelectric power plants can be vulnerable to droughts and climate change, affecting their reliability as a renewable energy source.
whatever you want the advantages to be.
