It’s always good to have a backup plan. We had planned on camping at River Run, a Corp of Engineer campground, but found the entry road closed off because all of the sites were underwater! A little playing around with my photo program and we had a nice but wet site. :-D Actually we stayed high and dry, camped at the little country park conveniently located across the road on the high bank of the river. The park has set their rates the same as the COE and they even give a 50% discount (except for the sites with sewer hookups) for Access and Senior passes which is unusual.
Shadowrock Rock has three types of sites. The sites along the river have concrete parking pads, water, and electricity and are very close together. Eight have sewer hookups. Sites in the next row are under the trees with water and electricity, gravel to park on and a little more room. The tent sites are the nicest - in the grass and under the trees with a lot of room between the sites.
