So, let's get into some speculation here.  All opinions welcome.

 The Russians are evacuating civilians from Kherson, supposedly to protect them from the coming battle.  But some people have speculated that if the Russians get all the civilians out of Kherson, and then if the Russian army loses the battle for Kherson and they have to evacuate and give up the city, that they will either blow up the hydroelectric dam and flood the city, or they will nuke the city.

My bet would be, if the Ukrainian army is occupying the city, the Russians blow up the dam and flood the city.  There's a small chance, though, that they will nuke the city after the Ukrainian army occupies it.
