It's generally a Class 2-3 river at normal levels with the Class 2 warmup upstream of the Rt 32 bridge. At higher levels the very portagable and identifable pillars rapid gets into class 4.
The river holds well and isn't miserable at low levels.
The hardest rapid is Hell's Teeth (aka Pillars). It has a hole that can get pretty nasty at higher flows...nasty as in it flips a lot of people, but it's deep and spits you out once you get upside down. The center pillar catches wood, often near the waterline , which sometimes isn't very visable.
The most dangerous rapid is Factory below the 2nd dam which drops down a chute of large cobbles.
LOW HEAD WARNING. In the fall of 2021, Hurricane Ida undercut the small dam on river right below the 'packman' rapid, the rocky drop below Forge Hill Road. After passing Forge Hill road bridge, the river turns right down the bumpy 'packman' rapid and then left before a building.
For those who've run the river before, this used to be an inconsequential drop of about a foot. Ida probably undermined the dam (and closed off the river's left channel at normal flows). At higher levels this is a significant recirc and though probably not uniform enough to be a true keeper isn't fun to be in...sneak as far left as you can get away with...at higher levels bump down to the left of the island.
There are two big dams during the run. The first at the Rt 32 bridge you can generally slide over without any problems except for boat abuse.
The second has a kick-up at the bottom that's quite a wall of water at high levels. (2021 update - center dropped so doesn't kick up as much).
The Moodna Gorge cuts thru glacial till and changes after every flood.
The old (pre-2010) hazards of I-beams below the Jaws rapid and under the Old Forge Hill bridge were eliminated by Hurricane Irene which moved the entire river to the right some 100 feet .
The Class 2 section above the Route 32 Bridge is a beautiful stretch of river where you will see some wildlife but not much fun at low water. As you'd expect there's access along route 32. There's also a class 2 section below Forge Hill Bridge with good parking and ok pullout just upriver of 9w on river left.
At high levels, the first three-quarters mile of Woodbury Creek is fun with a rocky slide past the Blackrock Fish and Game club (good for cheers on sunny Saturdays). Put in near Creamery Road. But don't go higher on Woodbury Creek. Moodna above the thruway is flat water all the way to the rocky chute below the dam below Beaverdam Lake.
