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
