LITTLE ROCK, Ark. – The Army Corps of Engineers is advising people in flood plains downstream of Beaver, Table Rock, Bull Shoals, and Norfork dams in northern Arkansas and southern Missouri as well as Greer Ferry Lake in central Arkansas to maintain awareness and monitor lake levels and the weather. These lakes’ flood pools are partially full from recent rains and more rain is forecast in coming days.
People should decide beforehand whether to move livestock, equipment and belongings to higher ground. Flows downstream can increase quickly, with perhaps no more than an hour or two notice; and rapidly changing conditions can create even shorter notice. The closer to a dam you are, the faster changes in river conditions can occur when releases from a dam are changed.
People in at-risk areas should stay in contact with local emergency officials, if larger than normal releases are required from a dam, warning will go out through local emergency management channels.
It is worth noting that lakes cannot prevent all flooding. Once a lake is full, larger than normal releases have to be made. The lakes have limitations that Mother Nature can exceed, and from time to time does. Therefore downstream property owners should be judicious in how they develop land within the flood plains.
Floods are not as frequent because of the dams, and when they do occur, they are typically not as severe as they were before the dams were built. But there will still be occasions when significant floods occur downstream of these dams.
If you experienced flooding in the high water events of 2008, 2011, or 2015, you could again experience flood waters in the same areas.
Planting crops on land that floods on occasion might be profitable in the long run, but building a home or business on that same land might not be. Farming, running a business, or having a home in the flood plain of a river comes with a risk that each property owner should take seriously when heavy rains are in the forecast.
