Hi all,
We are starting to see some spring run off come down from the mountains. As a result, yesterday and today we are bumping up releases at Green Mountain Reservoir to the Lower Blue.


Yesterday afternoon, we bumped up releases to 500 cfs.


This morning, we bumped releases up again to 600 cfs.


We can see multiple operations changes during spring, so please be sure to check the gage before you head up to the Lower Blue.

As always, feel free to contact me with any related questions or concerns.


Best,
Kara

Thanks Kara.

How about one "bump" to 4K and blow those strainers outta there? We won't tell. :mrgreen:

Just sent this out:
All,
As run off continues to come down from the high country, we continue to bypass the inflow through Green Mountain Dam to the Lower Blue River.



At noon today, we increased our releases from Green Mountain to the Lower Blue by 200 cfs, putting the river at 800 cfs.



Friday morning at 6 a.m. we will increase the releases again by 200 cfs, putting the Lower Blue at 1000 cfs.



Saturday morning, we will increase another 200 cfs around 6:00 a.m and Saturday afternoon we will increase one last time by 200 cfs, resulting in a 1400 cfs flow in the Lower Blue by Saturday evening. We anticipate the flows will stay in place up to five days before we begin to scale back down.



These releases are part of the Coordinated Reservoirs Operations program that we, and other reservoir operators, voluntarily participate in during run-off seasons when we have surplus inflow. The surplus inflows are bypassed downstream to the Colorado River, for benefit of the four endangered fish under the Upper Colorado River Endangered Species Recovery Program. The Recovery Program will issue a news release tomorrow further detailing our releases and those of other reservoir operators in the Upper Colorado River Basin.



As always, please let me know if you have any additional questions.



Best,
Kara

THANK YOU KARA! The worst strainers have been washed out of the way. The bad one below the gorge is now hung up on the second weir, but not blocking the entire river as before. The new trees upstream are mostly parallel to the river and easily avoided.

Kara,

Is there something the Bureau could do about those two hazardous man-made weirs on this run? The weirs have the hydraulics of extremely dangerous low head dams. Perhaps a safety chute at each one?

Lynne,
Unfortunately, no. We have to release water for authorized purposes. E-mail me offline and I can better explain.

Best,
Kara

You mean the ones after the canyon rapid?

Those aren't always sticky. Removing/altering them would mean contacting the US Army Corps of Engineers.

Hey Kara -
Thanks for the updates - I just noticed that the Lower Blue has bumped up to over 2000 today. Any idea how high it's going to go, and for how long? FYI to all you rafters out there - I think this might be too high to fit an oarframe under the pipe and bridge out in the ranch section. Ran it at 1800 last year and barely squeezed under.

Hi,
I just posted another note--started a new thread. Forgot to look for this one.

We are at 2100 cfs. now.

Might go up more. I'll do my best to keep you posted!
