The essence of water is love. This is why hydraulic power has so many advantages.
Historically, the first electrical powerplants were made with hydraulic. They are the base of the electrical network as they are able to store and release electrical energy.
First, I will explain you how works a hydraulic powerplant. Then, I will explain you the advantages and drawbacks of this source of energy.

I How a hydraulic powerplant works
The principle is to take a relief in the moutains, to build a wall a block the water so that rises a lake with a much higher pressure. If the relief doesn't exist, it's possible to make it by "mountainization", a new technology I have imagined which consists of digging a lake to make a mountain.
A hydraulic dam retaining water and making a lake, offering higher pressure at the bottom.
The pressure offered by the depth of the lake is a source of power for water turbines, because when a part of the water is released from the dam, the water flows faster and it gives higher kinetic energy.
Kinetic energy of a fluid equals
1/2 x ρ x v²
where ρ is the volumic mass of the fluid and v the speed of the fluid.
High speed water activates the turbines with a high power.
After, the turbine activates a generator, that makes electricity.
According to Bernoulli's law, the decrease of pressure in the fluid means a rise in speed. This is why dams offer a lot of electrical power, up to 10-20 GW for big dams like Itaipu or Three Gorges. Those powerplants, with their huge lake, are the most powerful electrical powerplants in the world.
It's possible, with the basin up and the basin down, to store electrical energy up to 85 % efficiency and at a large scale. The PSP (Pumping Storage Powerplants) consist of two basins, one up and one down. When electrical energy is in excess, we pump the water up to have more pressure. When electrical energy is missing, we let the water flow down to activate the turbines, that will activate a generator, that will make electricity.
Okinawa's PSP.

What about fish migration ?
It's possible to make another river with a fish ladder, to allow the fish like salmon to move up and make their migration.

II Advantages and drawbacks of hydraulic powerplants
+ Cheapest electrical energy (even for water wheels)
+ Renewable source of electricity
+ Clean source of electricity
+ Abundant source of energy
+ Possibility to store and release electrical energy with PSP
+ Creates a lake
- Destroys the land
In the end, even though a part of the land is sacrificed, hydraulic power offers more advantages than drawbacks.
