Almost certainly too low for any reasonable whitewater. Virtual gauge approximates flow at take-out of lower reach. Flow up here may be only 1/3rd of that!


River Description

With only about 7 square miles of drainage (a quarter-mile below listed put-in), this is obviously extremely small, and will 'go' only when everything else is in flood (or near flood conditions. That said, it appears there are a number of great rapids, ledges, and falls in this "Top Slate" reach.

Rapid Descriptions

Confluence (Class N/A, Mile 0.3)

At this confluence (of unnamed trib with the Slate), drainage is roughly 7 square miles.



Bridge (Class N/A, Mile 0.9)

It is possible (likely) that using our listed put-in may only add swiftwater and class I-II warm-up water, plus a high potential for deadfall and snags. It may be preferable to use this bridge to cut off that upper stretch and start with better action which begins pretty immediately downstream.



Falls (Class N/A, Mile 1.2)

Looks pretty wild (on satellite view) . . . probably merits scouting!



Ford (Class N/A, Mile 1.9)

Downstream there is much decreased gradient. While it makes for a very short run, boaters may prefer to take out here.
