Too low to boat. |
140 - 300 cfs |
somewhat Low-barely Low |
I-II |
Technically boatable, but really very scrapy. Might be good for a very timid boater that is very new. Expect some new scratches on that boat. |
300 - 700 cfs |
med runnable-a bit pushy runnable |
II-III |
Best flow for small play. Low end of this range is a little scrapy. |
700 -1200 cfs |
barely runnable-high runnable |
II-III |
Good flow and getting bigger. More wave trains and some catch on the fly stuff starts to pop up. Many of the big play spots are still in. |
1200 -2500 cfs |
a bit pushy runnable-high runnable |
III |
Flow is starting to get quite fast, some stuff has washed out, fun wave trains, and some playspots may be gone. Some of the banks are in the water. |
3500 -5000 cfs |
a bit pushy runnable-high runnable |
III-IV |
Very big and fast. Expect most things to be washed out, but what is still there to be big. Swims at this level can be very bad at this level. |
5000 -20000 cfs |
barely High-extremely High |
V+ |
Anything above 5000 cfs is not recommended. Some have gone higher than this, but not much. Bridges may be unpassable. |
