This news about the McCloud River just popped up in my inbox (from Curtis Knight, CalTrout):

I received word form the PG&E operators that, due to the high levels of rain over the past few days, PG&E operators will begin increasing the water release at McCloud Dam to Lower McCloud River early this afternoon and that the reservoir will be in spill conditions by this evening.

Additional information about the estimated duration and magnitude of the spill will be available later this afternoon.  I will send an update as more information is available.

Yow. When the McCloud spills, it gets unfishable pretty quickly.

Planning to fish it this weekend? We’ll wait and see if you will…

See you being swept down on the McCloud, Tom Chandler.

UPDATE: (May 6, 4pm) From CalTrout – “They are not spilling over the spillway right now.  Right now (2:50 pm) flows from the dam are 160 cfs, at Ah-Di-Na are 621 and into Shasta is 2,500 cfs”
