Which map is the best for buliding hydroelectric dam?

Any map.
You can build a dam anywhere. However if you want to use more of the natural terrain rather than terraform your own, then look for a good supply of water in large volume and differences in terrain height. This is important since it isn't just flow that determines the power output. The difference in height of the water volume behind the dam and in front of the dam is crucial.

Open any map in the editor.
Create a hollow mountain up to maximum world height.
Place the largest water source as high as you can inside the mountain.
Place another largest water source at sea level below the mountain.
Open the mountain wall facing the water source at sea level.
Build walls to make sure water only flows between the two water sources and doesn't escape.
Start the map.

The river leading out into the ocean (not the one coming from the lagoon) on lagoon shore produces a steady 500+ MW for me, that's the highest I've been able to muster without terraforming or using sewage outlets to force-feed a dam.

The Islands map has a spot for a 1600 MW dam (maximum output). I think it's two tiles away from the start so it'll take a while until you can build it without any mods.

I started new city in two river map does is good?

As grapplehoeker says, any map if you don't mind terraforming. I followed his guide and got a (questionable) max output dam as seen in this screenshot:

My budget is set to 50% which is why it shows 800MW, but the overlay power is below that !!
