Description

This was known as something else earlier, but almost everyone calls it Denny's Run now.  This rapid can either be pretty sweet or completely lame, it really just depends on the day and water level.  It also is constantly changing, so you really never know what you are going to get.  This is generally the best rapid of the day and the one that gives the most people issues.

The river constricts down to about half it's size and goes left down a gradual drop.  Depending on where the rocks are, you can get some 3-4 foot waves in here.  The waves are big enough that kayaks without spray skirts will take on decent water at the right levels.  Complicating matters are the ever-presence of trees at the bottom of the run.  Because of this, paddlers usually catch the river right eddy to avoid the strainers.  The eddyline is crisp and flips novice boaters with delight.  The only spot on the river with consequences, but usually the carnage happens at the eddyline as opposed to the strainers.

Having said all that, this has been the spot of several swiftwater rescues by local fire/EMS with people that have gotten stranded on the strainers in the middle of the river.  Canoes and kayaks have been seen wrapped around the trees, so the hazards are real in this spot.

NOVEMBER 2012 Update:  Currently on river left at 2100 cfs, there is a nice 2-3 foot green wave for front surfing.  Carving is easy on the wave.  You can set yourself up by first catching a river left eddy above the wave and ferrying above the wave to another eddy in the middle.  This sets you up perfectly for the surf.  However, once you're off it's hard to get back in that eddy in the middle.
