| Thomas Jenner posted BNSF 7305 east, H-TPLTUL (Temple, TX - Tulsa, OK), crosses the Arkansas River in Tulsa, OK at milepost 424.6. The Arkansas River is currently flowing at 104,000 cubic feet per second and 22 feet stage feet in Tulsa. 5/23/2019 16:50 [To put that in perspective, I think 100 kcfps was the original design limit for the Oroville Dam's Spillway.] |
Officials Encourage Flood Preparation as Keystone Dam Releases Go to 250,000 CFS "Water flowing into Keystone Lake should peak this afternoon around 320,000 cfs." The new Oroville Dam spillway design can do more than 200 kcfs, but I think the number is less than 250 kcfs.
A USACE spokesperson at around 27 seconds left in this video states that the channel's capacity is 105 kcfs and they are spilling just 86 kcfs, so no problem. I guess she hasn't got the memo about the 250 kcfs release!
I think a lot of the news articles I was looking at were using file footage for the video because the lower arm of the Tainter gates angled down. But here is a video where you can see that the first few gates on the left side have the lower arm at an almost horizontal angle.

From http://www.swt-wc.usace.army.mil/KEYS.lakepage.html Note that the hydro plant has been shut down. Another thing I learned from the Oroville disaster was that when the downstream level gets too high, they have to shutdown the hydro plant so that it does not get flooded.

This is the only photo I found with the lower arms close to horizontal. Then I noticed it was taken in May, 2019.

TOM GILBERT/Tulsa World [Many of the photos before this one show that some zoning authority allowed a subdivision of houses to be built on a flood plain. But I could not find where "South 145th West Ave. near Oklahoma 51" is on the map. At the bottom of the gallery is a video that starts with the muddy waters pouring over the Keystone Dam.] |
Update: I just saw a view of Tulsa on the Weather Channel showing what looked like a downtown area under water. They were making a point that they are going to stay at the current flood stage for many days because even more rain is on the way.

ATTENTION: The release values for the graphic above are inaccurate.
Please use the bolded red release value below. Which is based on several measurements by the USGS
of the flow at the 71st street bridge in Tulsa. NO gate changes were made at Keystone Lake last night.
The current data for the gage mentioned above can be found HERE and HERE.
Thank you for your patience we are working to correct the issue.
