OK, Google Earth was behaving this morning, so here’s an update on the directions. From your description, I suspect you have already read the stuff on Southwest Paddler, at
http://southwestpaddler.com/docs/little5.html" onclick="window.open(this.href);return false;
This would be “easy” now, except for one thing: Marc (SW paddler) apparently has some typo’s in his GPS coordinates. (It happens, I’ll send him an e-mail).
The correct location for the put in is: N34.2081 W94.2289
(I’m assuming the put in is near the dam; if signs direct you to the campground instead, then go with that.)
And the correct location of W road 80000 (also known as County Road 70) is: N34.11069 W94.20626
If you have a GPS or car navigation system of any kind, you should be able to enter those numbers into the system. If you don’t, then go to this web link:
https://maps.google.com/" onclick="window.open(this.href);return false;
“Cut and past” those coordinates into the search bar. You can then hit the “Directions” tab, and enter any starting point you choose (GPS coordinates, street address, or even just a local town like “Wickes, AR”), and get a detailed turn-by-turn set of directions.
I also recall a really nice surfing wave (when they are releasing) at the take out bridge; but don't remember whether we were taking out at the first bridge, or at W80000. It was good enough that we even drove down to "park and play" a couple of times, so that is something you could do on the day you have to start your drive home. It was fun in a tandem canoe, so I think your touring kayaks would also find it "surfable" if it is still there and not gone due to gravel bar changes or something.
For release information, I can only suggest you try calling the Corps. Contact information for Gillham was listed as:
