Frank, I am down there on almost a weekly basis. by June there shouldn't be any water issue problems. Most of the flooding issues are on the White River and the authorities have closed Lock and Dam #2 which should protect Arkansas Post from those waters and the Mississippi.

As for what is there?

As you are asking this questionon this board I am assuming that you are interested in the war period of Arkansas Post. It is mostly a park and a small visitors center and a few interpretive panels, very general in nature. They are more interested in the early settlement and for the most part very little is done for interpreting the War years or the Battle. There are one or two artifacts such as the 6th Texas Infantry flag in the visitors center. The fort and most of the fortifications washed away in the 1927 and 1935 floods. So other than some of the foundations of the old town there is not much else physically appearent there.

You can probable get more solid information about the battle from the historians on this board than you will from the rangers at Arkansas Post, unless you are just going there to see the lay of the land.
