Is the Nipper River Controlling the Black Sea?

The Nipper River goes through it so anyone that controls it can prevent ships from traversing the Nipper and going to the sea. It's basically a sandbar and you know it's really really hard to do anything there from a sort of defensive fortification perspective. I think it's actually rather unlikely that Ukraine intends to conduct a river in operation to cross the Napper there and attack your zone they don't have to right? They can conduct an offensive operation east of the river into Zaparija, he says.
