Ice jam, levee breach causing flooding in Colona, significant rise of Hennepin Canal


An ice jam on the Green River caused flooding in and around Colona and a breach of the levee system, causing a significant rise on the Hennepin Canal. 

The Henry County Office of Emergency Management said an ice jam upstream of Henry County Highway 15, known as Green River Road started around 7 a.m. This initial jam caused a breach of the Green River levee system, which allowed water to escape the river and enter the Hennepin Canal.

Moderate flooding is occurring along the Hennepin Canal State Trail in and around Colona. This area remains closed to traffic and recreation.

Local officials have visited the area and continue to monitor the situation. At this time, The Henry County Office of Emergency Management says there are no evacuation orders necessary. Warning signs for high water have been placed on impacted area roadways within Henry County.

Residents are encouraged to remain vigilant of rising flood water and notify the Henry County Sherriff’s
Office of any significant changes to the current situation at 309-937-3911. 

Please do not drive or wade through flood waters, no matter how deep you think it is. 


Flood waters have washed over Green River Road in the Colona area, according to the Henry County Sheriff’s Office.

Green River Road is closed from the Hennepin Canal to Cleveland Road.

The flooding is due to an ice jam, significant rainfall and a levee breach in that area of the Green River.

The Henry County Office of Emergency management is on site to investigate and asks that you avoid the area and report impacts.
