How was your run? I think there was 20-40 coming out of fourmile creek.
I'll be working up four mile on and off over the next couple weeks, and would be able to get after the buttress section some afternoon next week for wood and metal removal.
I took Riley down Black Rock last summer at 128 and 143 cfs. Everything had enough water and almost clean lines except for some of the slowest wides parts above rigor.
Here's Riley's you tube channel, It'll have his ski edits and other paddling stuff, as well as Bike jumping: Riley Frank - YouTube
