camo12, I was in the same situation about 7 years ago. Most of the river bottom I was hunting flooded out, pushing nearly all of the deer out. We are now in a 5 year drought so the river bottom has been dried up for 5-6 years. The deer numbers are currently very high (partly due to much more cover such as grass and weeds from the flood), though it took a couple years after the flood to completely rebound. I would guess the deer numbers will get back to normal within a year or two for your area also.

The flood was actually a blessing in disguise for us. When the deer were pushed out of the river bottom for a couple years, it allowed breeding with deer from outside the river bottom (those with better genetics). So we now have much nicer bucks running around in the river bottom. Since this is public land, our local Game and Fish dept. has been planting corn and clover since the water went down so that has helped bring the deer back.
