2007 Chevrolet Cobalt Clutch and water damage

I drove by water 3 days ago, I let it dry and now when I try ro drive my car revs up, but it won´t accelerate, I can´t pass 20 miles per hour, some people have told me it´s the clutch, but before spending 300 dollars on a clutch set, I need to know if the problem could be anywhere else or I just give it more time to dry.
