There's never really enough water at Uwharrie to hydrlock the engine. It's so hilly, and they do a good job of run-off/erosion management there. Most of the water will run off into nearby creaks. then they lay logs parallel with the stream to allow water follow and also allow vehicles to cross the creek without disrupting the flow so much. There's always been very little water to worry about, the mud was just slippery as hell when it rains.
