Cool, the russian army is unable to defend their dam against an Ukrainian attack. What a bunch of newbies those russian soldiers are. A dam... not a building, a dam, a huge block of concrete and they were unable to even defend it.

The dam sluices were Russian controlled but the dam is on the front line. It easily could have been attacked by either side.

Wrong, you don't destroy a dam just like that. It takes preparation and a lot of explosives at the right points. This is not a Micahel Bay movies we're talking about.

Both sides will see flooding but moreso the Russian side because it’s flatter. Breaching the dam will empty the canal providing much-needed water to Crimea. The lower water level upstream could threaten the safety of an offline nuclear plant upriver. I can’t tell which side controls the plant, so I’m not sure who that would affect more.

And Putin doesn't care about all of that. He has proven it again and again.

I can’t tell which side controls the plant

Russia, They took control of the plant, which is illegal, all nations around the globe know perfectly that no army should take control of a civilian power plant. Every other army is trained to carefully avoid the nuclear power plants. For some reason Russia keeps ignoring the international laws.

But Ukraine could have done it for the reasons stated.

Nonsense, but keep trying

We’re definitely still in the fog of war and it’s ignorant to assume we know all the details.

Textbook Russian propaganda here -> "Nobody knows for sure".... Well, keep telling you that, nobody believes you west of Russia.

The dam was under Russian control and they sabotaged it to slow down the Ukrainian counter offensive. It's fine, Ukraine knew it was a possibility and they have plans accounting for it.

The lower water level upstream could threaten the safety of an offline nuclear plant upriver.

The plant is in the cold shutdown right now, so while it still need some water as cooling, the amount is way lower than in case of normal work, so even in the worst case of complete dam destruction it will not be affected as it is now.

I can’t tell which side controls the plant, so I’m not sure who that would affect more.

Currently Russia.

Russia could have easily done this to distract Ukraine ahead of it’s counteroffensive and to make the river harder to cross.

Problem is, nobody proven that offensive is even real, not to mention that it was prepared there. Currently the most intensive fights are being waged somewhere else. Also Russia recently hit at least two or three huge UA ammo depots which probably really did hampered any preparations. And the battle of Bakhmut was colossal meat grinder where regardless if we agree on exact numbers, Ukraine lost some of their best soldiers remaining (exactly those who would spearhead the offensive) and Russia lost mercenaries.

Both sides will see flooding but moreso the Russian side because it’s flatter.

Also basically all Russian defensive positions along the river were destroyed, countering the guy above on similar level i could say UA surely hit it because it will make their attack much easier when the flood lessens.

Finally, UA already had plans for exactly that action last year, as they admitted to WaPo:
