Jerry stated that Floyd is the landowner. However, to be sure, since there is contention among the lake natives, I'd check with the clerk's office, armed with my own printout of the map/aerial so they can pinpoint the exact property, to be sure.
If I fished that property with any regularity methinks that written permission from the ramp landowner would make things a lot better, just in case some nosey third party tried to rain on your parade.
