Ukrainian dam breach: Was it sabotage by whom?

Update 6/7/2023: As we learnt in the news yesterday, there were at least three factors contributing to the dam breach:

1. The Ukraine bombed the street across the dam last year
2. Russia allowed the water at the dam to rise to very high levels
3. The dam may have had pre-war structural issues due to lack of maintenance or for other reasons

That the dam breached apparently multiple times may rule out an accident.
