1/2/2007 update: In addition to the tree, a rock tunnel has been cleaned out and is now a hazard at higher flows. See http://coastals.org/forum/viewtopic.php?t=3116 and scroll down a bit for details.

The USGS recalibrated the gauge stage / cfs relationship in November of 2005. The river has run so seldom since then it took me this long to notice the discrepancies. From what I can tell, for example, at USGS 2.6 feet what used to be 638 cfs is now reported at 511 cfs. Seems like a minor difference but if your zero is 600 then it makes the difference between a day at work and a day digging the Pass!
