Title: Keystone Lake Flooding Post by: baby83 on July 06, 2007, 08:30:09 am I know on the news they are saying that keystone can hold alot more water. Well, I went over the Keystone Dam yesterday and it's about 10-15 Foot from going over the top! The whole Keystone State Park is flooded. There's already houses in the Prue area that are flooded! Let's hope the dam doesn't break. If anyone knows any websites for early tulsa flood pictures. I would appreciate it.
Title: Keystone Lake Flooding Post by: Porky on July 06, 2007, 08:37:31 am I'll wander over there this morning and take some pics. If Prue is getting flooding, Cleveland should be as well.
Title: Keystone Lake Flooding Post by: Breadburner on July 06, 2007, 08:38:26 am Not even close to what happened in 86.....
Title: Keystone Lake Flooding Post by: sauerkraut on July 06, 2007, 08:50:36 am They say since the new flood controls installed in 1984 Tulsa will flood no more. This is putting Tulsa to the test big time. If Tulsa can stay dry now Tulsa's future flood worries may be over. The problemo is the ground is just over saturated. Water has no place to go. Thinking about that, it's no wonder that 1957 Plymouth vault flooded, saturated ground from all the flooding years of the past. We are lucky in the mid-west we have dry & sunny weather this summer season.
Title: Keystone Lake Flooding Post by: rwarn17588 on July 06, 2007, 10:09:33 am Since I actually live in Tulsa, sauerkraut, I can vouch that the drainage system during the recent rains has worked like a champ.
You had the usual places where it flooded, such as underpasses. But that system installed in the 1980s has been showing its worth throughout. And since we're forecast to have a few days with no rain, I think we're out of the woods. BTW, "10 to 15 feet from the top" of any dam isn't all that worrying. Title: Keystone Lake Flooding Post by: Conan71 on July 06, 2007, 10:12:59 am I rode over the Dam on Weds. It's high, but I wouldn't worry about it. Breadburner is correct, they have much more data gathering equipment these days to keep flood waters better managed. They have many upstream and down stream stations to help keep water managed better.
I wouldn't worry about the strength of the dams, they will hold. Tulsa Corps Website (http://"http://www.swt-wc.usace.army.mil/") I'm going up to Oologah tomorrow. I've heard they won't let us out to sail. The water is up 18 feet higher than it was this time last week. I was up there Sunday when it was already up 5 feet. They originally thought it would be higher than '86, but so far, so good. My boss' brother was just in my office. He lives near Edwater Acres and Twin Mounds off Oologah. He said the water is up over their fenceline and in places the fence is completely under water. Title: Keystone Lake Flooding Post by: sauerkraut on July 06, 2007, 01:40:19 pm quote:Yes but the flood controls can't help much when the ground is all saturated with water and the water has no place to go but build up in pools and puddles and spread out. It no longer can drain away in the soil. If the rains keep up you'll get flooding. Title: Keystone Lake Flooding Post by: shadows on July 06, 2007, 02:11:19 pm We have been assured that the dams will hold by the corps. Rumors that there are cracks in them is false. They are made of better concrete than our overpasses, bridges and roads are made of.
The drainage basin of the 61 square miles of the Mingo has not received past or present the rainfall that created previous floods. One could check with the weather bureau and the storm water management water gages before we get too excited Title: Keystone Lake Flooding Post by: edward_apovi on July 06, 2007, 02:20:50 pm yeah its monsoon season here lately, i much prefer this to dry seasons from years past tho, its less hot and everything still grows. you can go outside in the rain and swim and have fun still, and the rivers are nice.
Title: Keystone Lake Flooding Post by: Conan71 on July 06, 2007, 02:21:04 pm quote: The point is, we've already had our flooding, we are waaaaay past saturated. This is as bad as it will get for this rainy season, unless the weather patterns change again and we get a ton more rain up-stream. Title: Keystone Lake Flooding Post by: TheArtist on July 06, 2007, 05:16:33 pm I think someone on the news said that we have only received about a third of the rain in the Keystone watershed that we got during "the great flood". Just heard them say that right now the Arkansas in Tulsa is flowing at about 60,000 cubic feet, it can handle 100,000 cubic feet, and to put this in perspective during "the great flood" it was flowing at 300,000 cubic feet. Lake Keystone and the Arkansas in Tulsa is no where near flooding like it did then.
Course my backyard has turned into a marshy, mosquito infested swamp. [xx(] Title: Keystone Lake Flooding Post by: Porky on July 06, 2007, 05:40:07 pm I didn't see any flooding today and that included my trip to Prue. So everything is fine there baby83. [:)]
I agree with all of you that there isn't a problem in Tulsa with flooding coming our way, unless we get some real storms to the north. Saying that, Keystone Lake and the Arkansas River are brim full. Here's some of the pics I took today: Click Here------> http://tinyurl.com/25acpk ....you can see in the pictures where the River Walk in Jenks might have a situation, if flooding would occur. Title: Keystone Lake Flooding Post by: cks511 on July 07, 2007, 09:10:21 am I taught school and lived in Bixby in 1986....this is nothin.
Title: Keystone Lake Flooding Post by: Conan71 on July 07, 2007, 09:23:28 am Riverwalk crossing is on the outside of the Jenks Levee. As I remember water went over the levee in '86 didn't it?
We went paddling in a canoe on the sod farms down in Bixby that year. [;)] Title: Keystone Lake Flooding Post by: waterboy on July 07, 2007, 09:44:19 am We have to put our faith in the guys opening the gates ever so carefully. They all know what happened when they were careless in the past.
My memory is that we have exceeded 100,000 cubic feet per second since that time and have not had flooding. You could find a history on the corps release site. Spokesman for corps said they may have to go to 130,000 about a week ago but never did and its currently 58,000cfs. I am not too concerned. But I live atop a hill, I'm only worried if the dam breaks and I'm jogging on the path! Title: Keystone Lake Flooding Post by: shadows on July 07, 2007, 04:42:16 pm If you are jogging and the dam breaks you will possibility do some high speed cross country running.
The weather radar at the weather station showed the 86’ storm as a red screen as the tropical storm moved up the Keystone drainage basin. They seems to have warned the corps of the inflow and the gates should be opened to compensate. The corps did not respond until they realized that the inflow would breach the dam. Then the gates were opened and flooded a large area down stream. I believe that the Keystone flood pool will hold an 1 1\2 inch rain fall over its complete basin. They are trying to hold back the water until the two rivers to the East of Tulsa get down the Arkansas and are back in their banks. It is interesting to note that the flood on the Mingo in 84’ that created SWM was predicted as a 20% chance of rain. Until the others rivers pass their flooding an unpredicted rain storm in the Keystone basin could cause another 86’ flooding disaster. Title: Keystone Lake Flooding Post by: waterboy on July 07, 2007, 09:19:00 pm quote: Could happen, but I doubt they will make the same mistake they did in '84. As per a story in the World ten years later, they trusted rather unsophisticated devices relaying inflow of creeks upstream. Rather than immediately sending corpsmen to double check dubious readings from the equipment, they opted to wait till it was almost too late. Their upstream monitoring is better now. One of those cases where technology really is helping. Now its just a case of balancing out the flooded areas. Title: Keystone Lake Flooding Post by: cannon_fodder on July 09, 2007, 08:43:22 am Here is my question:
With 50+K cf/s for a couple of months, did we wash out some of those sand bars? Surely most of the sediment settles out in the backwaters of Keystone and there just isnt that much area to pick up new stuff from Keystone to 21st street. Keep scouring, there has to be a rock bottom somewhere! If nothing else, we cleared out the trash. Title: Keystone Lake Flooding Post by: Conan71 on July 09, 2007, 11:57:04 am I motored out onto the water Oologah Saturday evening (not enough wind to sail). It's almost spooky. Where I'm used to seeing trees as shoreline land marks, those are mostly under water. Water is now at the top of 20 foot rock walls and into the treetops of campgrounds.
There were only two other boats out that I could see. I passed a 25-30 ft. log with birds perched on it in the middle of the water, along with several uninhabited ones, and saw all kinds of interesting floating debris. As I understand, the purpose of Oologah is aside from flood water management, downstream navigation (McClellan-Kerr), drinking water and recreation, it's also supposed to be a repository for upstream silt to keep it out of the navigation channel. |
