But there’s a chance that, cut off from the sea, the water collected wouldn’t be enough to offset losses (evaporation, etc), right? Kind of like how the Mediterranean was dry when it was cut off from the Atlantic?
A telling sign is that the baltic sea gets less salty the further you go away from its connection to the north sea. That means that the water is flowing out of the baltic sea, so putting a dam there would only slowly rise the sea level.

Well, no, its too far north for that to happen.
