"The Nova Kakhovka dam and hydroelectric plant has been largely destroyed and few structures remain," Maxar said in a statement.
The images show houses and buildings submerged in water, with many having only their roofs showing, and water taking over parks, land and infrastructure.
Ukraine said Russia had committed a deliberate war crime in blowing up the Soviet-era dam, which powered a hydroelectric station.

The dam was damaged in November following Russia's withdrawal from the Kherson city.
