0 - 250 cfs |
extremely Low-barely Low |
I(II) |
Too low for reasonable whitewater outing. |
250 - 750 cfs |
barely runnable-med runnable |
I-II(III) |
Low-to-moderate flows, appropriate for novice to intermediate whitewater paddlers. |
750 -1200 cfs |
med runnable-a bit pushy runnable |
II+(III) |
Perhaps 'optimum' flows for good intermediate whitewater paddlers. Will be pushy (scary/dangerous) for less experienced paddlers. |
1200 -6000 cfs |
a bit pushy runnable-high runnable |
II-III+ |
High, pushy, big, flushy, with waves and wavetrains. Strong, experienced paddlers may find fun. |
6000 -20000 cfs |
somewhat High-somewhat High |
II-III+ |
Unusually high flows. Expert whitewater paddlers may find waves/wave-trains entertaining. Others are urged to refrain from paddling this section at these flows |
20000 -50000 cfs |
somewhat High-extremely High |
III+(IV) |
Flood level flows. Huge, pushy, likely mobile strainers (floating branches and whole trees). Utmost caution is urged for anyone running at these flows. |
