Good Morning, America was in Algonquin this morning (Monday, July 24, 2017) with a live report about damaging flooding in the Midwest.
The community that straddles the border of northern Kane County and south McHenry County, has been hit with some of the worst flooding in Illinois and remains under a Flood Warning, with the river reaching a new record level 13.15 feet — 3.65 feet above flood stage. As of 7:30 a.m., the river remained at 12.8 feet.
According to the National Weather Service charts, the Algonquin Tailwater levels will be above the moderate flood level through the rest of this month — even without additional rain.
The Fox River remains closed to recreational watercraft, and a Flood Warning remains in effect for the Algonquin Tailwater and the Fox River at Montgomery until further notice.
At 8:15 a.m., the stage in Montgomery was 14.1 feet — more than a foot over the flood stage of 13.0 feet. The river will remain near 14.1 feet through the afternoon, and additional rises may be possible thereafter, the NWS said. Flooding in Montgomery affects homes on River Street near Ashland Avenue.
Kane County Emergency Management Director Don Bryant reports that sandbags are available to the public at the Kane County Transportation garage, 41W011 Burlington Road, St.Charles and at various municipal locations.
To date, Kane County has deployed more than 30,000 sandbags, and the affected municipalities have distributed thousands more, Bryant said.
