Comment: Ran Upper Duncan. Nice amount of water flowing to make it fun but not difficult.

Comment: The bathtub at R8 had a non-trivial hydraulic. People were positioned at the end if it to help others escape. the rest of the raps are splashy but not threatening. Overall nice day out. the rain was active and water levels were higher coming out than going in. Didn’t spend a lot if time it the quad to keep our thermals up. Fun day out and good conditions to get experience. Higher side of moderate

Comment: Duncan surprised us today with more water than we expected. It was a tiny bit pushy but fun. We re-rigged the webbing on R4. We downclimbed the one small drop after the (old) logjam. A meat anchor for the best down climber is a good idea for this point and spot for the last person is recommended. A webbing anchor on the big log in the center of the creek would be a good idea for less confident canyoneers.

Comment: Ran the full creek today and it's in great shape! The section between the old log jam and the creek crossing is beautiful with nice bed rock and one nuisance rappel/careful downclimb. We put second bolts in for R2 and R3 to make the anchors redundant.

Comment: Training day in Duncan, so we ran R1-R6. Water was fun but not intimidating. The changes from the atmospheric rivers this winter are impressive! The small log jam DCR at R7 is gone. The BIG log jam is also cleared so you can now run all the way to the crossing. It's going to be fun to be able to run the whole creek without sketchy log jam scrambling!

Comment: Celebrating the New Year with a local freezefest! Great team and much fun out there, tho' sadly Duncan was not in full-on swiftwater mode. That said, the recent atmospheric river event completely blew out the big logjam below R8. All the logs blowing out revealed two new drops (both easy downclimbs) and some gorgeous bedrock. Clear signs of scouring along the canyon walls from the big release when the dam blew. Wowza.

Comment: Went to check out Duncan for a high flow run. Water was over the banks at the bridge so we walked in to look at the lower section. Very high water so we bailed and went to run Munra. Duncan will be raging after the rain coming this week!

Comment: The water came up a little today after the rain but is still low. Careful on any jumps due to the low water. There's a bunch of new debris/floating logs below R7. Not clear where it came from but it doesn't pose a hazard right now.

Comment: The past 24 hours of rain have raised water levels a little bit, and the level actually rose a little while we were in creek. Cold day in the rain, but we were already wet anyway! Hopefully the rain keeps the flow a little higher for a few days.
