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.
