1995 Geo Prizm 15 inches or more of water

I was driving and didn't realize water was so deep. I was already in it so I tryed to just keep going. When I switched gears it died. I pushed it out of water and had it towed home. Has not started since. When I try to crank it it makes loud clunk noise. I believe the motors locked up. Last thing I need right now. I took air filter out and some other stuff. I know water has gotten in to the intake. Checked oil and it looked fine no water. Tried to get a push and pop clutch but still nothing, but when popping the clutch it did not make my tires squeal it just keep rolling like motor is not locked up. My first standard and front wheel drive car and know nothing at about them please help. I need to get back into my school before its to late. Thank You
