We made some changes on the Fry-Ark project today. Here's a note I sent out:
Today on the Fry-Ark Project we have started to wrap up exchanges against native inflows. Additionally, we are starting to see run-off inflows increase into Twin Lakes. As a result, we will be ramping up releases from Twin Lakes to Lake Creek over the next 36 hours. The anticipated schedule for increases to releases is as follows:
Today, June 10, 3 p.m.: 270 cfs, bringing total release to about 290 cfs.
At 8 p.m. we will add another 250, bringing the total release to around 540 cfs.
Tomorrow, June 11, at 7 a.m. we will increase a third time by 250 cfs bringing the total release to Lake Creek to 790 cfs.
Depending on run-off conditions, we might add a fourth increase later in the afternoon on June 11. I will keep you posted.
I think this is kind of a "jargoned" note I sent and I am trying to make it better. I know a lot of folks familiar with water understand "exchanges against native inflows," but not everyone does. So, I'll give it a go:
Essentially, when native inflow is coming into Twin Lakes, if an entity has water down in Pueblo Reservoir, they can exchange it against what is coming into Twin. So, if they have water in Pueblo they want to exchange and 100 cfs is coming into Twin Lakes, they can release 50 out of Pueblo, keeping the lower Valley whole, and store their other 50 in Twin. effectively moving their storage from Pueblo to Twin via an exchange.
So, during the exchange times, native water into Twin Lakes is not being released down the Arkansas. Now that the "native exchanges" are wrapping up, and inflow is coming on with run-off, we're bumping up the releases from Twin Lakes.
This isn't quite as finessed as my other explanations and I apologize. I'm trying to get better at describing exchanges and substitutions and it is not without its challenges.
