If it were mine, that river would scare me, if the water could get high enough to flood it.
Several years ago, a construction company near here was rebuilding a bridge and/or small dam across our little river. Friday PM, it was raining; they shut down for the weekend, AND LEFT BACKHOES AND CRANES in the river bed (behind the temporary diverter dam they had built.
Well, it rained Sat and Sun. By Sunday evening, water was level with the top of the cabs on the cranes.......... I think they dragged the backhoes out before they got in too deep.
They lost a lot of $$$$$ on that deal.
