There are several COE parks and one SP around Lake Ouachita. We stayed at Tompkins Bend CG. 50 Amp electric but no water at individual campsites. Campsites on the outside of some loops are water front so just paddle from your camp. Lake Ouachita SP has FHU sites. Never got there ourselves. Lake Ouachita has miles of shoreline to paddle around. Check out Street View on Google Maps as they drove through the campground and you can pick which site you like best. Dogs allowed. With driving distance for a day trip to Hot Springs NP. Garvan Woodland Gardens SE of Hot Springs is also worth a visit if you like botanical gardens.
As noted above, the Buffalo National River has some stretches of flat water for kayaking, depending on water level.
Park Info Dogs are permitted in CG's, on the river and within 100' of the rivers edge, but not on trails. Must be on leash.
Beaver Lake in NW AR also has several COE CG's. For kayaking, I personally would prefer Lake Ouachita over Beaver Lake as Beaver Lake has a lot more development and houses around it while Ouachita seems a little more natural. But Beaver Lake is near Eureka Springs, worth a day of exploring. Pea Ridge NMP is an interesting Civil Was site I knew nothing about until we stopped there. Crystal Bridges museum in Bentonville has lots of great art and is free. My kind of price and I'm not one to go to art museums anyway but glad I went.
