Prius C flooded till rear hybrid fan vents

Dear all,
My Prius C (Toyota aqua) got flooded in urban flooding in my area Karachi Pakistan.
Water inside was up to rear hybrid fan vent totaly drowned in water.....
Engine oil, air filter, and other main components are dry or have no sign of water into them. Oil level, brake oil and collants are same as before flooded.
Now I used bucket to throw water out and tried to see if engine will show READY sign ....which it didn't.
Is hybrid battery strong to face such flooding ?
What other damage I may be expecting as gear EV and ECO mode button were also underwater.
Anyone have any idea of such flooding and it's consequences?
