NWS Springfield

.LONG TERM...(Monday through Saturday)
Issued at 129 AM CDT Sun Apr 30 2017

The next shortwave riding through a northwesterly flow aloft will
arrive Tuesday night and Wednesday. This system will interact with
front stalled just to our south to bring another round of rain and
some thunder. Rainfall amounts of one to two inches may occur
Tuesday night and Wednesday.

At this point does it really make any difference? Everything is just going to be full longer.

That is an amazing amount of water and rise considering every foot up spreads out over more and more land.

100,000 cfs is 18 acres a foot deep per minute. That is crazy numbers. Thanks for the updates.

Is the James and King dropping or maintaining their flows.

The video from Powersite you could see it increase as it ran. That was a huge WOW for any engineer.

[NotJLB]

James: 83700 cfs (increasing)

Kings: 30000 cfs (decreasing)

As if we didn't need another complication, now it is windy.

A lot of docks are unacessible, and were left with loose cables, to keep them from breaking as the water rises more. So, now they are swinging back and forth, with tremendous pressure on cables.

Dockwise, I have no idea what they do with them on Taneycomo, with all that current, when it gets like this.

If Bottom Power Pool is 880, how does the following make sense leading up to rainy season?

Jan 01 to Apr 30 915
Apr 30 to May 01 915 to 916

They are mostly designed for strong current. Heavier, and more numerous cables. Plus most of the docks are not in shallow water coves where they need to be drawn in and out with rise and fall. A lot of them are using steel framed "swing arms", for the lack of a better name. Connected to a heavy concrete anchor post with a large pivot pin. They still have twisted, came apart, and broke loose. Was it 2008, or 2011 that Bas Pro's dock broke loose, and was finally stopped way down lake? I think the same year Fall Creek Marina lost their dock. Broke up, and drifted away. Some of it was behind Monkey Island for some time.
Guess we're gonna find out. Just heard they pulled the stopper out. 50,000 cfs heading for the Landing.

My latest scoop (2 hours old) is that they are open 49,000 and that the predicted crest is 933-933.5 occurring about noon Monday.

[rjw1991A1]

936 is the magic number. From our 2008, 2011, and 2015 episodes, we learned that at that level the catwalk to open the gates is under water. So, it's that catwalk that is the bugaboo

Thought that was taken care of. I remember reading that the CoE was seeking bids for work to correct the prpblem.
No more ploitics allowed on 1b, so I guess we can't say why it wasn't if it wasn't

***URGENT MESSAGE FROM BRANSON EMERGENCY MANAGEMENT***
This is an emergency message from the City of Branson Emergency Management. The Corps of Engineers will be increasing flows from the gates of Table Rock Dam from 49 thousand to 65 thousand cubic feet per second at 6 pm. Please take appropriate actions to secure personal property and evacuate areas prone to flooding when flood gates open. Remember, utility services in these areas may be turned off if affected by flood waters. Early evacuation prior to dark is imperative.

65000 going out and 83300 coming in just from the James.

Little bits of rain in the area now. 2 inches expected Tuesday night.

[NotJLB]

The spillway release from Beaver is the same amount as the spillway release from TRL.

Beaver got stopped going up at 1131.25 22 hours ago. Now it is right at flood stage, 1130.

TRL has not been stopped yet, and is at: 01MAY2017 1400 934.53 It's hovering around there, about to be stopped from going up.

James and Kings are both backed off quite a lot, but James is still 33600. Kings is 6800. Those and what's being released from Beaver is still more than is being released from TRL, so figure it out.

KC bridge is closed, so it's the long way to and from town. I did some sight-seeing coming home today.

Cold and windy and nasty today.

NWS for Tuesday night and Wednesday:

Generally speaking, we are looking at 1.50" to 2.50" amounts. With soils saturated and rivers/streams very high, this rainfall will only add to the
flooding concerns.

[biscuitcreek]

Norfork has crested and the release from the dam is being lowered. More info from KTLO:

[NotJLB]

I can tell we have dock damage, likely a broken cable at least. It was OK until it got windy. It will be awhile before I can access/assess it, and see what else there is.

Ours won't be the only one.

Peobably not add to as much as extend existing levels. Just filling back up what is being drained now.

I am seeing 933.82 for TR. Is that correct. If so they have it going down. Unbelievable how much water they can get rid of from that lake thru the gates alone. Good grief.

Looks like they dodged the bullet again or ...its a calculated and carefully executed plan that seems to work every time? Hmmm...
