we put in at the USFS office, not an official ramp but a nice little bank to the river and less than 50' carry from the adjacent parking lot to the river. i was in a 12' raft with fishing frame, and had no problems with bridges below that point. a couple of braids in the river were moving fast and pushing against the brush/trees on the bank, so we just got out and walked the raft thru some of those spots. water was moving fast and the fishing sucked, and that was at 585 before the recent bump to 750.
we actually took out just above BRCG at the fishing access/eddy (the "normal" bridge referenced by salto) that is the common put in for the white water run. BRCG was not open on sunday, but it is reported on 9news that it will be open by memorial day (Tree planters take on the Mountain Pine Beetle | 9news.com
the stretch between town and the fishing access was nice enough but is better suited for fishing, no white water. i have run the white water section down to the columbine landing about a dozen times in the last few years, and it is a blast. a 16' bucket might be a little tight at current flows IMO, but the water will be higher soon and you should have no problem then. there are some decent wave trains that will put water into your bucket boat, and the action is fast and fairly constant which may be a problem if you need to bail in the rapids. i saw some guys lapping it in bigger cats last year around 1200 and they did fine, and saw some folks with what appeared to be a 14' SB going on sunday at 585. don't take the 16' on the fishing stretch i described above, it will snag up for sure in some of the braids.
CL III+ is a fair rating in my opinion up to and above 1000, and i think IV- is fair above 1500 or so. it is over quick, last year we did 3 laps in about 4 hours after lunch one sunday. i am planning to be there this saturday or sunday, i am trying to choose the warmest day to drive up from denver. later.
