Don't know of a "comprehensive" list, no one has one for just all campgrounds either. But, in Indiana, the State Parks are open year round for camping. Water is turned on in the campground beginning early April and turned off the end of October. So, no water in the State Parks. But electricity is still on and you just drive in, pick your spot, set up, plug in, and enjoy. DNR will come around and collect a very reduced fee during those "off water" months. FYI, dump stations are still open too, but no running water.
FYI, anything South of Indiana (Kentucky, WV, VA and Southward) will be open and have full functionality, depending on each campground set-up. We've camped several times in Kentucky the week of Christmas for our annual pilgrimage to South Carolina or Florida during Christmas week. Always have water at those overnight stops (we stop at KOA's). Once we hit Indiana, private campgrounds are closed, and water is off at State Parks.
