Please hold releases at 35,000 cfs until further notice.

Comment:  Insufficient head on Spillway gates to increase releases further at this time.  Additional release increases will be made as reservoir storage allows.

After some back and forth about how high the flows should go, Reclamation has settled on 60,000 cfs by 5pm today. The change order is below. Here is a nifty link from the CA NV River Forcast Center about projected inflow.

High Flows at Nimbus Basin

Posted on Wednesday, January 4th, 2017

Interested in the high flows over December in Nimbus Basin? So are we. Thankfully, Reclamation used their last aerial flight to capture 35,000 cfs on the LAR. The files are gigantic and somewhat painful to stitch together, shrink, and upload, but here is a great shot I had to share. I’ve paired it with pre and post-project photos to remind everyone what it has looked like under all that water. We hope to spend time this year assessing what has happened to our restoration sites and discuss returning next year.
