Key to the Columns of the River Tables
[ Back to main page] | [ To alphabetical river table ]
- River
- Which river
- Section
- Which section of the river: start and stop
- Dist
- Distance - length of the section
- Class
- Based on International Scale of River Difficulties, class
I to class VI, augmented by A, B, C for smooth water
- Grad
- Gradient: first number is mean drop in ft/mile; second is
maximum drop (see the Guide for technical details)
- Area
- Size of drainage basin, square miles
- AvgCFS
- Average flow, cubic ft per second. Note that this varies
widely through the year.
- Size
- Qualitative description of the river's size, for the less
technically inclined
- Nearby Gauge
- A stream gauge that is on this river and close enough to
be reasonably correlated with the section
- Lo OK
- Lowest gauge reading for safe and pleasurable canoeing.
Note: for water up to class III, the high and low tend to
reflect water levels for open canoes. Decked boats may
prefer more water.
- Hi OK
- Highest gauge reading for safe and pleasurable canoeing
- Aux Gauge
- A stream gauge somewhere in the general vicinity that may
give some guidance, but cannot be assumed to be as well
correlated as a gauge that's actually on the river. Also,
an unofficial gague such as a staff gauge or instructions
to count bricks on a bridge pier.
- Lo OK
- As above
- Hi OK
- As above

As always we have made a serious effort to present accurate
descriptions. However we are human, trails change with time, and we occasionally
receive incorrect information. Therefore we can not be responsible for
discrepancies between these descriptions and actual trail
conditions. Use common sense, judgment and be careful out there.
