How many of you knew there was an Illinois River in Oregon? And get this: it has excellent rapids.
The Illinois River is not rafted as often as the Rogue since there is no dam upstream of put-in. The amount of water in the river is directly related to rain. If it rains too much the river can rise to an unsafe level (above 3000 cfs) within a couple of hours. The river can also drop below runnable levels after a few days without rain. This makes a trip challenging to organize since trips are often cancelled due to high water, low water, or potential bad weather. The extremely high quality of this river trip far outweighs the potential of a cancelled trip.
