Sandy

The Marmot gauge is currently wrong, it read about 370, but we found it had about twice as much water.  A better correlation right now is to subtract the Bull Run flow from the Sandy below Bull Run, at least until the rains come and side creeks start distorting that calculation.  As reported on social media previously, a large boulder has fallen into the normal left line at Boulder Rapid creating a serious hazard. At this flow, 80 to 90% of the flow deflects right off of this boulder and into the undercut.  I understand that at higher flows a few people have successfully negotiated this, but at lower flows it's unreasonable and possibly fatal to attempt.  The left slot on the right route is currently open, the narrow slot just to the right has wood in it that apparently is hidden by higher flows so keep that in mind.  The portage on the left seemed a little trickier than usual due to some extra rockfall.  If the portage gets blocked by wood - which has happened - and the right slot gets blocked by wood - which happens - you could find yourself with a serious dilemma.  Years ago, someone got cliffed out on the right bank after a swim and had to be rescued by ropes from above after a helicopter attempt knocked a rock down on top of him and broke some bones.
