Kyle, I think I understand your situation. I have some inlaws who have an 80 acre pecan farm on the Verdigris river near Coffeyville. It floods the trees every year. A few years ago the water got over the tops of some of the trees, and the trees didn't seem to suffer much. But there is a world of difference in pecan trees, and traditional fruit trees, from a flooding standpoint. My advice is not to plant anything but pecans on the lower acres. One big flood will kill any traditional fruit trees. If you have upper ground, you could plant in terraces, as Hman suggests. Apples, depending on the rootstock, can take some mild flooding once established, and there is a market for them. Plums and pears also tolerate some excess water depending on the rootstock. The problem with plums, is trying to get a good looking plum, which has been challenging for me. It's been much easier for me to grow peaches. Unfortunately they are among the least tolerant of water-logged soils. Non-traditional fruits like persimmons, and to a lesser degree, pawpaws will handle more water, but trying to find a market for the fruit could prove difficult.

Lucky you! It's a native & the fruit is reportedly sweet & delicious - I have a very small 1 in a pot waiting for transplant.... Here is a link that might be useful: Chickasaw Plum info

I've only been in the house since November so I can't tell you too much. I think it will get good sun in the summer and it will get good sun when it grows taller. I am just trying to get an overall plan for the yard. Ill start researching those fruits you mentioned.

I bought a house with a backyard that is a former 60 years old citrus grove, one of the reasons I bought this specific house. The north part of the grove was Washington Navels and the south part was Valencia. The original home owners planted Minneola Tangelo and a Pink Blush Grapefruit, now 40 years old. Originally I was working on restoring it to look like the grove it once was but now I"m adding enough that it will look different as I have too many trees to fit. It originally had about 18 full size 20' diameter trees but I'm adding a few different varieties and have 58 original trees plus trees planted plus trees in pots to plant. WAY too many so one 100' side is now going to be Espaliered citrus along the wall. Still have 6-7 in pots in the front walk. Another 5 different Avocados. Just grapefruit: Pink Blush, Duncan, Oro Blanco, Melogold, Rio Red, Valentine, Cocktail, Chandler Pomello. Of course, this many trees in drought stricken SoCal is a problem so I now am working on 1920 gallon rain water recovery and grey water recovery system. In the meantime, I have 8 42 gallon trash cans in the inside roof corners that get filled each rainstorm so I water with almost all rainwater recovery. I'm not addicted, really!
