ILLINOIS RIVER BASIN CONDITIONS
AUGUST 20, 21 & 22, 2010 WEEKEND FORECAST
This Weekend is the 18th Annual Illinois River Balloon Fest in Tahlequah. Also, be sure to mark your calendars on Saturday, October 16th to attend this year’s OSRC “Illinois RiverFest.”
As Illinois River water levels and flows are now at seasonal lows, it is recommended that individuals planning to utilize rafts or inner tubes for their float trips should opt for taking shorter length trips given river conditions. In the event individuals chose to take a raft or inner tube float trip that covers a river reach 10 miles or longer, it is recommended that those float trips should be launched prior to 9:00a.m., to allow adequate time to complete them safely and during daylight hours.
