In case you have time for a ten-hour drive, Idaho is going off as well, with more boatable flows than Cali.
Climax Wave on the Payette was in this weekend so the Main is running like 4,500. The North Fork looked to be around 2,000 but cold and icy in spots. The Salmon was around 6,000.
I recomend the Little Salmon (tested this week); warmer than the Payette this time of year. It was between 1,600 and 2,000. All the hair was in at the top and the surf was awesome. 3,000 ups the fun, making it a play run that'll put you on the edge of your thermoformed seat. Tons of mini-skook waves with continuous rapids. No swimming......
A word of warning: None of the guages seem to be working but they're getting the same pineapple express we are in Colorado with half the elevation. Try the Bliss Wave on the Snake to break up the drive.
