Repairs to damaged gates could happen in early August!

Forsyth MO. - On or about June the 28th of this year, some form of flood debris damaged a part or parts of a pneumatic line that was used to inflate air bladders that would raise or lower the gates as needed. When this line was 'cut', a goodly section of the barrier lowered, allowing water to flow freely from Taneycomo. On July 15, I was able to get in touch with a spokesperson at Liberty Utilities who informed me that repairs would have to wait until the water level on the Bull Shoals side had dropped enough for it to be safe. I was told that level would be 685 feet above msl. (I had posted 675 feet and got a correction notice from Liberty Utilities - see update below)! A situation that could be hampered due to Bulls Shoals Dam in Arkansas having to restrict their release rates, somewhat, until things improved on the Mississippi (my assumption).


While it may be hard to see in the graphic above, those little black triangles represent sensors that show when the body of water they are located on is above flood stage. It would appear that the Missouri and Mississippi rivers were both a little high, (to say the least). What is not apparent, yet, would the be effect of all the rainfall dropped on the Mississippi by tropical storm Berry. Again the bottom line is, in my limited view, it could be quite a long period of time before these main waterways get back to something close to normal.

 Update From Liberty Utilities:

'Heavy rain and flooding conditions in the lower Mississippi river valley have impacted several of the lakes in our Southwest Missouri area. 

Flood debris recently caused damage to two sections of the spillway gates at our Ozark Beach dam on Lake Taneycomo. Because of the damage, these spillway gates can’t be raised due to broken or cracked air lines. A breach to the dam has not occurred, and there are no immediate safety concerns. Crews will repair the air line damage once the water level in Bull Shoals lake has dropped to 685 feet, allowing them to safely access the dam equipment. Until that time, residents may experience dropping lake levels at Lake Taneycomo. 
If you plan on boating at Lake Taneycomo now or in the near future, please check the lake levels before entering the water and practice caution while traveling on the lake. Repairs will be made to our Ozark Beach dam as soon as conditions allow.'

Extrapolating from that new guideline and assuming that we do not experience any more heavy rainfall in the near term, I cam up with the following graphic click on to expand):

If correct, the 685 foot level could be reached at or before August the 10th! That's a big 'if', however.

Powersite Dam barrier broken and utility company seems clueless!

Forsyth MO. - On or about June the 28, Powersite Dam suffered a mechanical failure in a water blocking mechanism that normal projects up a few few allowing water to be withheld up to 702 feet or so. This insures that folks living along the Taneycomo waterway have water for their boats and docks to ride on. When it fails, the water is allowed to flow freely and so some dock owners awoke to find their stuff high and dry! Now it's been a couple of weeks and no repairs had yet been forthcoming.

I was also told that the Corps of Engineers were withholding water from Table Rock dam in an effort to get Taneycomo's level down far enough to replace what had broken. Powersite Dam, which is run by Liberty Utilities (formerly Empire), seemed clueless when a recent call to their Corporate office came up empty. No one seemed to know what the status of this repair effort was at! And, while they promised to call me back when they had an answer, I was left wondering just who is in charge concerning the Canadian owned enterprise... I'll post an update when I hear back from these folks.

Update: Monday, July 15, 2019 - I talked with a spokesperson from Liberty Utilities and was informed that the damage was to a pneumatic line that services the movable gates and that it will be inaccessible for repair until such time as the Bull Shoals water level drops to or below 675 feet msl. This morning Bull Shoals was at 687 feet.

Powersite Dam problems!

Forsyth MO. - On or about  the 28th of June, 2019, a air bladder mechanism failed at Powersite Dam resulting in the top retention area lowering. This allowed water levels at Taneycomo Lake to plummet to such an extent that some dock owners went out to find their docks were resting on mud!

The effects of lowering water levels fro 702 feet msl to 698 were easy to see! Areas that were normally covered with two to three feet of water were laid bare!

Almost two months later and the flood remains!

This side-by side-comparison of water levels in Shadow Rock Park taken May 9th and June the 25th show why I’m concerned about the future use of the park areas that are so much a part of life here where I live in southwest Missouri. It’s a number of months since we experienced those spring rains that originally caused the problem, but now I’m beginning to wonder if the lake levels will ever get back to ‘normal’. I’ve lived in this area for over twenty years and cannot remember this stretch of Bull Shoals flooding as often as it has recently. I also don’t remember the water level staying so high for so long!

So, where’s the figurative plug in the drain? That would be the Bull Shoals Dam across the Missouri border in Arkansas. Problem is, if the officials were to release the backlog too quickly, they would potentially re-flood a good portion of the state as the White River meanders its way southward. (A casual inspection of the White river, using a site like Google Maps, shows that it runs a very convoluted course with many small towns located along the way). Small riverside towns like Batesville flooded along with many others when the heavy rains fell back in May. So, that’s part of the problem. Any large release up stream right now would just re-flood areas in Arkansas.

Adding to the woes of the Corps of Engineers, recent and continuing heavy rains in the northern Midwest states have added historic amounts of flood water to the Mississippi which is only now beginning to recede back to more normal levels. After nearly two months above flood stage, the waters are now at 47.95 feet early Wednesday, June 22, bringing along with it a shared sigh of relief from many. The question on everyone’s mind now is what the fall rains will bring.

As of this writing, the lake level for Bull Shoals stands at 690 feet plus change. (Check the river levels chart comparing the last three years for some insight as to what that means). Hopefully, that level should begin dropping more rapidly, especially if the Midwest remains relatively dry. Maybe we’ll all get a chance to use the park areas later this fall right before winter sets in!

In aftermath of storms, the Powersite dam is still flowing!

The Powersite dam is still flowing at a good rate (as of May the 3rd, 2011) even though the water levels on the other side are now approaching normal levels. Hopefully, the levels in the parks downstream will now begin to go down and the locals will be able to enjoy planned activities this coming summer and fall.

 

While I was walking near the dam located, I came across this Zebra Swallowtail butterfly (Eurytides marcellus). This species is found throughout the middle and southwest parts of the county and is striking in it coloration.
