Yes, CR makes definite predictions. The "Great Flood" part was shown to be false in the late 1700s.
This is one way it differs from ID, which is in principle incapable of making predictions.
"The "Great Flood" part was shown to be false in the late 1700s."
Not really. More and more evidence is accumulating. If you look at the Paleozoic and Mesozoic sediments they are spread across vast areas, quite distinct from the cenozoic sediments which are mostly local in origin. Likewise, paleocurrent analysis shows that throughout the Paleozoic and Mesozoic, the paleocurrents on each continent were going the same direction.
Most people don't know this, but there is a pretty much worldwide unconformity separating the Precambrian from the Cambrian. It is pretty stark in the locations where it is visible. Likewise, there is a similar global unconformity at the K/T boundary. These are the basic markers of the begin and end of the global flood.
