This late April and now well into May 2017 rain has put a ton of water in the Grand Lake watershed and the lake is rapidly rising and on pace for a potentially record elevation level. (Note – NOT saying it’s going to happen, but is sure could with this event – either way…BIG WATER rivaling historic levels).

And that’s not good. For anybody.

Here’s what you need to know.

For the absolute latest information on the Grand Lake elevation and flood water releases at Pensacola Dam, there are a couple of things you can do.

First, for updates on the flood water release from GRDA, you can call the Ecosystems and Education Center in Langley at (918) 782-4726 for a recorded message. Not sure how often that is updated in high water events, but it is available.

You can also visit the GRDA website at THIS LINK for current lake levels, inflows and releases. It doesn’t tell you exactly how many gates are open at any time, but it does give you the most accurate picture of inflows and outflows.

And if you are on social media, you can find GRDA at a couple of places on Facebook, HERE is their Ecosystems and Education Center page and HERE is another page. On Twitter? Follow GRDA HERE.

Of course, everything that happens with the Grand Lake elevation impacts those downstream at Hudson, Ft. Gibson and into the Arkansas River, so it times of super high water like this all releases are made by the US Army Corps of Engineers.

Once Grand Lake reaches certain levels, GRDA no longer has the authority to start and stop water releases. They just follow through on their order.

We’ll keep you updated as best we can right here on this page with updates whenever we get them from GRDA.
