Stony

At the put-in drainage area is about 163 square miles (to the best I can do using online planimeter and topomaps).

First off, all which follows is via online aerial views of river, thus is very tentative and should not be considered or expected to be comprehensive or entirely accurate assessment of what may be found on this section of river. Anyone having first-hand knowledge is encouraged to help out your fellow boaters by adding a comment or report (with photos/videos if possible).

It appears there is one (or more?) bridge piers, and possibly considerable rocky rubble under the bridge, which may (or may not) create some minor opportunities for whitewater maneuvers.

Aerial view appears to show a river-wide line of rock (a rock dam, perhaps?). Perhaps minor play at some flows.

The river narrows, and nearly 0.2mile low-grade rapids will be encountered.

Another narrowing (after a pond), and another low-grade boulderbed rapids.

After more pool(s), another narrowing and low-grade rapids. Early on, an island is encountered. Right is wider (more of the flow), and likely more gradual, while left is narrow and may have a slightly more significant drop (still not overly difficult).

A short boulder field separates two pools. It may finish with a slightly more significant (playable) wave/hole.

A brief pool follows the prior drop. As the river narrows, a very minor boulderbed occurs, and a doubletrack crosses the stream. (This could be either a bridge or  just a drive-thru (ford) in the stream. If a bridge, expect it could be minimal (or no) clearance. If a ford, it could create a wave/hole at some flow(s).)

A (very roughly) midway point allows access/egress, as a road (and a good parking area) exist river-left.

Nip Creek enters from river-left.

A short boulderfield appears here, but appears it may have no gradient. At best boatable flows it may be covered and not even be noticed. At lower flows, it could be problematic finding a way through without getting hung up on numerous rocks.

Coming out of a pool the river narrows between rocky banks and has some apparent gradient. Expect some minor rapids and waves.

After passing a private property (river-left), it appears there is a small rock dam which may cause a wave/hole at good boatable flows. A very brief boulderbed follows before a short pool where the river does a sharp turn to the left, encountering another boulderbed with some good gradient.
