| Flow | Medium Flow |
We estimated the flow at 130cfs, subtracting the Helena guage from the Burnt Ranch gauge, taking 50% of that for the area of the North Trinity watershed, and 15% for the EFNF within the NF drainage.
On the drop just upstream of the bridge listed as the put-in on this page, a log now blocks the entire right line. The left line is slightly undercut but was not really in play at our flow. The position is very close to 40.8237, -123.1253.
There are a number of wood pieces in play, but eddy-hopping and boat-scouting allowed us to avoid portaging the entire run. Halfway through the run, there is a fresh, new river-wide log with all it's branches and foliage intact at the time of this writing. We were able to duck under it on our run, but at higher flows it will pose a significant hazard until it moves. Unfortunately, I wasn't able to coordinates for its position, keep an eye out for it.
