While I was looking for the photos of Creve Coeur Airport's 1993 flood photos, I came across my master book of images and notes from the event and our attempts to recover and get the aiport back up and running. I must admit, we did not wade out into the Missouri River and "give Mother Nature the middle finger", we did not have time. We had airplanes to clean up and an airport to rebuild. The flood of 93' leveled the playing field for all of us in the valley. The farmers quit fighting the airport at every turn and we started working together to pull the levee in and give the river more room. Of course we also raised the height of the new levee and built it to Federal standards. However, that was mostly stuff we started working on several months after the flood water went down. The first thing we had to do was save the few vintage aircraft that were still at the airport when it flooded. For you folks trying to clean up down at the LSFM, here are a few things that I remember from our ordeal. Keep in mind, advice is usually worth about what you pay for it. I'm no expert but we did learn a few things about dealing with wet airplanes, both wood and fabric stuff and aluminum skin types.
1) We started off buying ACF50 but it quickly became cost prohibitive. It's great stuff as is Corrosion X but we had to find less expensive methods of stopping the corrosion and rust until we had time to take things apart. The next step was WD-40 in drums. I've been told that the WD in WD-40 stands for "Water Displacement". No idea if that's really true but that's one of the things it does very well. We sprayed it on everything. I mean everything. It has an ability to get between rivets and the holes they are in and sometimes can work it's way around a rivet's head and the squeeze. Pretty soon, we realized that even WD-40 was more than we could afford in the amounts we needed it so we tried smoke oil aka concrete form oil. In the end, that worked well.
2) For parts, hardware, and any other bits, we filled 55 gallon drums with Kerosene and tossed the parts in with the idea that when we had more time, we could pull the parts out and clean them properly. I still have a few 5 gallon pales of misc bits that still yield good parts even fifteen years after the flood.
3) We had such a mess to clean up that at first, we started tossing things into the dumpsters rather than have to look at them. In some cases it was the right thing to do but in other cases, we wished we had kept the items. Save everything you can by preserving it now. You may decide to toss it at some date in the future but once it's gone to the dump, it can never come back.
4) Documents and paperwork, books and manuals can be saved more often that you might think. Commercial freeze drying operations did wonders for some the folks at another local a/p that got wet in the 93' flood.
5) I know you guys are in a wet climate all year but once you get stuff into small rooms, you can rent or buy dehumidifying units that create, at least to some degree, micro climates inside a room or a hangar. It takes time to dry stuff out like this but it does work. Of course I know this requires power and it may be some time before that is restored.
6) Fabric wings or control surfaces, even ones that were treated when covered, will grow mold once they get dunked in water. We sprayed copious amounts of anti-fungal chemicals into the fabric wings, fuselages, and control surfaces of several aircraft and managed to save them from rotting from the inside out.
7) If you have not done so already, find out if Texas has a Federal or State Surplus Property Division. In Missouri, they are combined into one facility. These groups usually have piles of cleaning materials like soap, preservative oil, gloves, etc. Sometimes, you can find pressure sprayers and steam cleaners.

Try to keep a sense of humor.
You folks probably know most or all of this stuff already. If not, I hope some of it is useful. Good luck, I'll be thinking about you all. Don't give up!
