Destruction of the Kakhovka Dam

On the 6th of June, the Kakhovka Dam in Ukraine was destroyed.  Both Russia and Ukraine blamed the other side. For Russia, this would cause issues with the water supply to Crimea and also risk safety at Europe's largest nuclear plant. For Ukraine, this means that not only are the areas that they recaptured to be flooded, but also this is going to be harder to cross the Dnipro River. When I say cross, Ukrainian forces already did this in April and it may be that the flooding may affect those who are on the south bank.  

Such an action will make it harder for Ukraine to retake Crimea, but I suspect that was going to be a hard ask anyway.
