More good news! This just arrived from Reclamation:

Our Wyoming Area Office has notified us that in response to recent precipitation above Boysen Reservoir, they will be increasing releases from Boysen Dam immediately to control the reservoir’s rate of fill.  Since we are approximately 10 feet from the top-of-conservation elevation at Yellowtail, we will be stepping up our releases to the Bighorn River in a similar fashion.  That means we will be increasing to 2,500 cfs on Tuesday, May 4 and then increasing to 2,750 cfs on Wednesday, May 5. 

These changes are necessary now so we can hold our current reservoir elevation and remain favorably poised to intercept the rule curve in early June. 

Reports indicate these flows will be sustained through the runoff period.
