Should we all start building Arks?

Taney County MO. - After a recent spate of heavy rainfall that dropped three and three quarters of rain or more over our area, the National Weather Service is calling for yet another round starting on Friday, April 28! Should this occur in the manner shown in the above graphic, it would definitely impact the upper reservoirs of the chain of three large lakes that form Beaver, Table Rock and Bull Shoals. (The short strip of water known as Taneycomo which connects both Table Rock and Bull Shoals could also be severely impacted if rainfalls meet or exceed the forecast amounts).

As of April the 27th, Beaver Lake that form the headwaters of the chain, was already at 1,125.98 feet which was above the full pool level of 1,121.0 feet! Note that the graphic shows a chance for rain potential to be over 10 inches. That much water falling on an already water soaked watershed would be immediately dumped into the lake with little in the way of absorption. This extra water would then be released at the dam into Table Rock lake which would also be 'under the gun' so to speak. Without going into too much detail, that's one heck of a lot of water that will be headed somewhere in a hurry! Remembering that while the system can easily handle such a load, the real problems would arise out of just how fast the whole system is impacted. Too much rain all at once would simply overload the whole smear...

Having stated all that, remember that what is forecast to happen and what actually happens can be worlds apart. Also, please note that this post constitutes the musing of an old fart with no formal training in the weather what so ever.
