Where Will All The Water Go

[lymorej]

I see that the Rock is at 927.17 this morning, and with the rain that is predicted over the next couple of days, is it possible to see the lake over flood stage or will they be able to control it? Will the Landing area be affected by this? I was just wondering how it all works.

Thanks

NWS Springfield office is warning that a dangerous flooding event is setting up. Saturated ground, creeks full to banks and more heavy precip. coming. Look's like Capt. Don's long range weather info. is coming true with heavy rain Thurs/Fri and more Sun/Mon. It all depends on where it falls and for how long. Makes you appreciate why the Govt. built the White River chain of Lakes back in the day.

Our weather lady up here last night said everything basically south of the I44 corridor could get up to 5-8" of rain. That would absolutely be horrible.

Have they opened the overflows? At what level will they open them?

It appears they are running out of storage capacity.

I believe 5 flood gates are open. I'm sure Phil can tell us what's up.

I do know they moved the Heartland derby from BS to the Rock for the 12/13th of April because they said BS was going to crest to high for safe tournament conditions.

It will be very interesting to say the least.

I would think TR would be in the same shape that early. I can think of alot of islands and low points that will probably be submerged for a while.

I'm not sure what the official name is, but I was thinking of the new gates they put in. I was wondering if there is a preset pool height that will dictate they open? Does anyone know if there is a limit in water level they will allow for Taneycomo if they do open?

The auxiliary spillway is the most cost-effective way to keep Table Rock Dam safe during a catastrophic flood. The new spillway will only be used during extreme flood emergencies.

Table Rock Dam was constructed between October 1954 and August 1958. It consisted of 4,821 feet of earthen embankment with a 1,602 ft long concrete section. The concrete section is designed to withstand the erosive forces of water released from the spillway gates at the top of the dam. The designers based the size of the spillway on the worst flood Mother Nature might reasonably create based on weather data.

Under the dam safety program, in the 1990’s, the spillway capacity was evaluated using improved weather data, and more modern technology and safety requirements. Engineers determined that the lake would rise ten feet higher during the worst-case flood than previously calculated. An event of this magnitude would overtop the earthen embankment and destroy Table Rock Dam with catastrophic losses in downstream areas including Branson. To prevent the potential loss of life and property damages, the Dam Safety Project was constructed. After considering several options and gathering considerable public input, the auxiliary spillway was determined to be the best solution.

denjac,

That reply of yours was "great" reading....well done !
