No first hand experience with this cable, but from looking at pictures I don't see how letting them stand in water (assuming no chemical contamination) will hurt them or effect performance. As long as the terminated ends weren't in the water you should be good to go.
If I were you I'd let them dry (apply no heat) and wire them up. If you want to be cautious, get a cable tester (<$100 at pro music stores) and test for shorts.
At a previous house we had repeated basement/water issues and the solution was to install a B-Dry interior perimeter drain system w/ sump pump. B-Dry is a proprietary system, but there are several competing systems.
