25 devastating flooding occurs along the Illinois River from Chewey Bridge to the headwaters of Lake Tenkiller. State Highway 10 is closed northeast of its intersection with Highway 51. Many cabin parks are severely flooded or are totally isolated for a long time. This is a very dangerous and life threatening situation. This will approach the April 2011 flood, which reached 25.97 feet. The record crest is 27.94 in May 1950.
23 extremely severe flooding occurs along the Illinois River from Chewey Bridge to the headwaters of Lake Tenkiller. State Highway 10 is closed northeast of its intersection with Highway 62. Several cabin parks are severely flooded and many others are isolated for a long time. This is a very dangerous and life threatening situation.
21 very severe flooding occurs from Chewey Bridge downstream towards Tahlequah. State Highway 10 is closed between Hanging Rock and No Head Hollow north of the Highway 10 intersection with Highway 62. Several cabin parks are severely flooded and many others are isolated. This is a very dangerous and life threatening situation.
19 severe flooding occurs from Chewey Bridge downstream towards Tahlequah. State Highway 10 near Hanging Rock and near No Head Hollow north of the intersection with Highway 62 is impassable. Some cabin parks are severely flooded. This is a very dangerous situation.
18 severe flooding occurs from Chewey Bridge downstream towards Tahlequah. Highway 10 near Hanging Rock northeast of Tahlequah is impassable. Some cabin parks are severely flooded. This is a very dangerous situation.
17 severe flooding occurs from Chewey Bridge downstream towards Tahlequah. Access roads east of Combs Bridge near Eagles Bluff are impassable. Some cabin parks may be flooded to a depth of a couple of feet.
15 moderate flooding occurs from Chewey Bridge downstream towards Tahlequah. Access roads east of the Combs Bridge near Eagles Bluff are impassable. Some cabin parks may begin to flood.
14 moderate flooding occurs from Chewey Bridge downstream towards Tahlequah. Access roads east of the Combs Bridge near Eagles Bluff will be impassable. Extreme turbulence makes the river too hazardous for floating.
13 minor flooding occurs from Chewey Bridge downstream towards Tahlequah. Access roads east of the Combs Bridge near Eagles Bluff may be threatened. Extreme turbulence makes the river too hazardous for floating.
12 minor flooding occurs from Chewey Bridge downstream towards Tahlequah. Extreme turbulence makes the river too hazardous for floating.
11 minor flooding occurs from Chewey Bridge downstream towards Tahlequah. Floating the river is too hazardous due to strong turbulence.
9 no flooding occurs but all recreational floating along the Illinois River ceases at and above 9.5 feet.
