Ridley Brook

This drop is somewhere in the 12-16 ft range I'd say.
This is pretty much what you'll find from the put in to the gorged up section, lots of boulder dodging , you get the idea.
Everytime i've been on Ridley I've portaged this entire rapid from the very top (where you start to see the houses on river left), but i've heard its marginably runnable. Guess you'll have to make up your own mind when you're there.
There is some wood in the lower slot on river left, looks like its wedged in there vertically, not sure how much in play it is, as again I've walked this one everytime I've been on here.
Gotta be my favorite on the run, its actually close to 8-9ft, you end up between two vertical stone walls, this river is beautiful especially for being roadside.
From the duxbury road bridge look downstream at the river right railroad bridge support. The concrete ledge sticking out from this is used as a guage. If the water is not covering this ledge its too low, otherwise its good to go (although i have done a run with the water level flush with the ledge...but wouldn't recommend it).
