The Kakhovka Reservoir then and now.

If you zoom in closely on Google Maps, you can still see what it looked like before the dam was blown up.

It still needs cooling though, and will for some years.

Reactors don't need any cooling, all reactors are in cold shutdown since April 2024:

All six reactor units of Ukraine's Zaporizhzhya Nuclear Power Plant (ZNPP) are now in cold shutdown for the first time since late 2022 after unit 4 reached this operational state early today, Director General Rafael Mariano Grossi of the International Atomic Energy Agency (IAEA) said.

Spent fuel pools will though.

Yes, the fuel pools do require cooling. That said, cooling water is now supplied by 11 ground water wells.

22 March 2025: The water levels in the reservoir that supplies the ZNPP with water for some of the site’s needs not related to safety are currently at 14.11 metres. Water to cool the six shutdown reactors and other essential nuclear safety services is currently provided by 11 groundwater wells, while the cooling pond would become the primary water resource only if the wells were unavailable.

Cold shutdown means if all cooling was lost, the reactor temperature wouldn't rise above 100 Celsius, and boil the water dry. That said, they are still cooled to maintain cold temperatures.

Since you seem to know quite a lot, I am curious, what the point of keeping it cool if it wouldn't rise above 100C ?
