Range | Water Level | Difficulty | Comment |
0 - 100 cfs |
extremely Low-barely Low |
II-IV+ |
Likely too low for reasonable whitewater. May be paddled as flatwater, likely portaging all gradient. |
100 - 250 cfs |
barely runnable-med runnable |
I-II(IV) |
Likely ELF (Extreme Low Flow) run. Some rapids may be runnable, others likely too grungy. (All the flatwater will be fine, though even slower than usual.) |
250 - 400 cfs |
barely runnable-med runnable |
II-IV |
Likely low-to-moderate flows. |
400 - 600 cfs |
med runnable-a bit pushy runnable |
II-IV |
Moderate to somewhat meaty flows. At 500, the class IV's are pushy, but the class III's were still a little boney. |
600 - 800 cfs |
a bit pushy runnable-high runnable |
II-IV |
Likely high flows. Some of the drops could develop rather aggressive holes. |
800 -1000 cfs |
somewhat High-somewhat High |
II-IV+ |
Likely unusually high. Many drops will be intense. Caution is urged. |
