The International
Scale of River Difficulty is a widely accepted
rating system. Ratings range from Class 1 (the
easiest) to Class 6 (the most difficult). What to
expect for each class is outlined below.
|
|
|
|
|
Class 1 -- few ripples, maybe some
small waves and few, if any, obstacles
|
|
|
|
|
|
Class 2 -- easy rapids with waves up
to 3 feet; wide channels with little manuevering
necessary
|
|
|
|
|
|
Class 3 -- more difficult rapids
with waves large enough to swamp a canoe; narrow
passages requiring manuvering
|
|
|
|
|
|
Class 4 -- large, long and difficult
rapids that usually require precise
manuvering
|
|
|
|
|
|
Class 5 -- terrifically difficult,
extended and often violent rapids with constricted
passageways (fantastically fun)
|
|
|
|
|
|
Class 6 -- generally considered unrunnable
even with a Mountain Dew
