While I would heartily welcome you to become a part-time resident of Stone County/Mountain View, you should know a few things if you are considering building on the White River.
1.) Stone County does NOT participate in the National Flood Insurance Program. You cannot buy flood insurance for your property if you live in Stone County, unless you live w/in the physical city limits of Mountain View. I don't know for sure where your potential lot is at, but there are no river front lots that actually lie w/in the MV city limits
2.) Most people building along the White River have a lot in the Alison/Sylmaore area, north of Mtn. View. The White River is also the county line. If you live on the east side of the river, you are actually in Izard County, and I believe Izard DOES participate in the Nat'l Flood Insurance Program.
3.) The White River floods. It's flooded quite a lot in the past few years. A river is not a lake, or an ocean -- it rises and falls quickly and unpredictably. Add to that the fact that there are a few dams upstream on the White River that can raise water levels after a heavy rain. I absolutely love the river view, but most people don't take into account how violent a river can quickly get. Build accordingly.
4.) There are lots of high places where you can build w/ a riverview while being quite far from the river. That is, if you don't mind living on the side of a mountain
