Degree of Difficulty
The
rapids which you will encounter on your journey down the Deschutes
range in difficulty from very simple to somewhat challenging.
Each rapid has been classified by its "degree of difficulty."
Minor rapids consist of Types 1 and 2; major rapids consist of
Types 3 or greater.
TYPE
1
Easy. Offers no major obstructions. Water surface shows
only small riffles. Low hydraulic forces are in effect. No significant
danger other than the simple, unobstructed force of the the current
of the river.
The majority of rapids on the lower 100 miles of the Deschutes
fall into this category.
The river we will be rafting falls into this category, with a
few slightly challenging rapids.
TYPE
2
Medium difficulty. Streamflow increases velocity. Obstructions
may necessitate some maneuvering. Medium hydraulics will be experience.
Small standing waves or relatively safe medium-sized standing
waves are possible.
TYPE
3
Dangerous. Swamping or overturning is common. Medium to
high streamflow velocities will be encountered. Standing waves
will be present. Powerful hydraulics exist. Maneuvering will be
required during passage. Dangerous suckholes may form at large
boulders. Midstream obstructions may be present. Novices should
seriously consider lining their boats through these rapids.
TYPE
4
Extremely Dangerous. Extended rapids necessitate long-term
difficulties. High standing waves and midstream obstructions force
maneuvering in powerful hydraulics. Suckholes are capable of capsizing
the most stable craft. Novices should not attempt. Novices should
line the boats through these rapids or portage around them.
TYPE
5
Extremely Dangerous. These rapids require technical maneuvering
in strong hydraulics. Rapds may be extended for some distance.
Standing waves and midstream obstructions or suckholes present
serious hazards to equipment and life. Novices and many experience
boatmen should line boats through or portage around.
TYPE
6
Foolish to Attempt. Involves life hazard. Waterfalls, impossible
hydraulics and necessary maneuvering combine to make safe passage
more a matter of luck than skill. Lining boats through or portaging
around in recommended for even the most competent boatmen.
