RX,
Hopefully it'll be down my then. Anything under 623' and most of the ramps should be open. There are some high water ramps available above that, but the one that I checked out didn't do much for me - I'm a little cautious.
For reference, normal pool is 606'. Today the lake is 640'. Previous record during the '93 flood was 637'.
Any recommendations for camp grounds around Mark Twain that I can park a 25' camper and have full hook up, at least water and electric for Labor Day? I looked the online reservation site for the state park and it showed all sites with hookups being booked.
