Upper Stony Brook adds 3 miles of class IV-V whitewater and 1 mile of class II to the traditional lower Stony Brook Run.  There are six class IV-V drops, and another half dozen or more class III or higher rapids.  1200 CFS on the Souhegan at Milford seems to be a rough correlation for a minimum fun level, though the gauge is a bit downstream.  At this level, the run is at most class 4+.  If the rapid under the bridge at put-in is fluid, the level should be OK.  See the pictures of the put-in rapid & takeout dam at minimum flows.  This run takes a while.  It is long, has a bit of wood, and requires a fair amount of scouting.  Plan accordingly.

The major drops are all easily scouted from the banks, and the smaller drops can be boat scouted.  This run is narrow and rarely run - be careful for wood.

The three most significant drops are  “Rectum,” “Railroad Bridge,”and “Granite Communications.”  Other notable drops are 'linoleum' and 'Backyard Brown'.

After a little boogie water will come Rectum, a double drop through a narrow mini-gorge.  The first drop can be boat scouted and run down the center, if there are eddies below.  At high water, there may not be.

The second drop of Rectum splits around an island then into a small boulder garden.  Both sides go, but look out for wood.  The whole rapid is class IV+ at low water, and V- at higher levels.  The rock is all railroad blast, so be careful.

Soon after Rectum comes Railroad Brigde.  Not surprisingly, “Railroad Bridge” is the rapid at the constriction below the overhead railroad bridge.  It is worth a scout.  Class IV at low water.  IV+ at higher levels.
