This is a better link to the actual flow on the murtaugh, USGS is usually missing some of the flows that make up the murtaugh
Bureau of Reclamation, Pacific Northwest Region Hydromet Program
Its around 3000cfs right now
All4ward you can raft or kayak down to 1500 or lower, just make sure to go with an experienced runner, or scout carefully, a couple of places you dont want to be. We have paddle rafted it plenty at 1500. The low flows make for a long day but the river falls into an inner gorge that is a blast in its own right just like the big high water murtaugh and everything in between. The Hansen Bridge (by Eden) is above paradise falls, unrunnable at higher flows but a blast right now.
