2007 Midwest flooding

Meteorological synopsis

The stationary front and associated energy then extended eastward through Illinois, Indiana and Ohio on August 19 and 20. Similarly, the front was the focus for thunderstorm development, and the precipitation continued moving over the same areas, leading to extended periods of heavy rainfall. Approximately 1,000,000 homes lost electricity due to the storms.

Runoff from the heavy rain also caused river flooding to the south of the affected areas. The Rock River near Joslin, Illinois peaked at 17.11 feet, 5.11 ft above flood stage. Moderate flooding was also reported on the Mississippi River from the Quad Cities to St. Louis, Missouri.

Illinois

The city of Rockford, Illinois was deluged in the weeks preceding the major flooding during the third week of August. On August 7, Rockford was hit by five to seven inches (127–178 mm) of rain. Many streets, including main thoroughfares, were flooded. There was also fear that the Alpine Dam might break. The following day, Governor Rod Blagojevich declared both Rockford and Winnebago County a state disaster area. With this declaration, he dispatched both the Illinois Emergency Management Agency and the Illinois Department of Natural Resources to assist the city. Debris removal, law enforcement, damage assessment, and other physical assistance were offered by the governor.

Two weeks later on August 23, violent storms rolled through most of the Chicago metropolitan area. Tornado warnings were issued during the first round of storms, which produced wind gusts as high as 80 miles per hour (130 km/h); the highest being reported in Manhattan. A small tornado was reported in Bolingbrook in a DuPage County Forest Preserve. The storms shut down airports (including O'Hare International Airport and Midway International Airport), uprooted trees and left over 600,000 residents in northern Illinois without power, some for several days. NBC 5 News The storms also caused flooding on streets and major expressways such as the Bishop Ford Freeway. Rainfall totals in Boone and LaSalle Counties topped 1987 records. Officials in Ogle County recommended that people in low-lying areas along the Rock River, and along Killbuck Creek near Lindenwood, evacuate to higher ground. Downstream, in Lee County at Dixon, the river had not reached flood stage as off August 25, though it continued to rise. Though not affected by flooding as it was on August 7, the city of Rockford received 1.23 inches (31 mm) of rain, setting an all-time record for Rockford's wettest month in recorded climate data history, with a total of 13.82 inches (351 mm) of rain.

Other rivers and streams in the Rock River valley experienced moderate to major flooding as well. The Kishwaukee River at Perryville crested at 17.57 feet (5.36 m), more than five feet above flood stage. The same river also rose above flood stage in Belvidere. After 4.85 inches (123 mm) of rain fell on August 23 and 24 in DeKalb County, at DeKalb, the South Branch Kishwaukee River rose to its highest level since 1983 and its second highest level in recorded history. DeKalb County received state disaster area designation from Blagojevich on August 26. In DeKalb and Sycamore, about 600 residents were displaced from their homes, and the DeKalb campus of Northern Illinois University was closed because of the flood.

The Fox River at Dayton crested after it rose to more than 17 feet (5 m), over five feet above the river's flood stage. In Plano, Illinois the Fox rose up around the historic Farnsworth House, a modern architecture masterpiece designed by Ludwig Mies van der Rohe. Preservationists used a boat to save the home and its furnishings, which previously had been devastated by high water in 1996. At Starved Rock State Park, parking lots were closed due to the level of the Illinois River, which stood at 26.5 feet on August 25, 6.5 feet (2 m) above its flood stage.

Governor Blagojevich estimated total flood damages could cost nine Illinois counties and the state more than $22.8 million, and the state requested federal assistance. On September 25, the Federal Emergency Management Agency (FEMA) announced that federal disaster aid was available for the state of Illinois to assist with recovery from the August storms. The disaster aid was made available when President George W. Bush declared DeKalb, Grundy, Kane, LaSalle, Lake, and Will Counties, in northern Illinois, "major disaster" areas. The federal funding made individual assistance available to flood victims in Lake, Will and Grundy Counties, and individual and public assistance available to those in DeKalb, Kane and LaSalle Counties.

Indiana

In Dyer, Indiana, southeast of Chicago, authorities evacuated 70 patients from St. Margaret Mercy Hospital after a waters from a nearby creek started seeping into the hospital. Also in northwest Indiana, a section of Interstate 80/94 (Borman Expressway) was closed on August 24 due to flooding on the roadway. It was reopened on August 27.

Iowa

The Des Moines River near Fort Dodge crested at 4 feet (1.2 m) above flood stage, necessitating the evacuation of three subdivisions. This was caused by rainfall of over 12 inches (304.8 mm) that fell in southeast Iowa during the night of August 23–24.{{cite web |archive-url=https://web.archive.org/web/20110629100628/http://www.crh.noaa.gov/crnews/display_story.php?wfo=dmx&storyid=9857&source=0 |archive-date=June 29, 2011 |url-status=live

Minnesota

A large swath of heavy rain fell across most of southern Minnesota during Saturday, August 18, and Sunday, August 19, with the highest totals in the far southeast counties of the state. Twenty-four-hour rainfall totals of 15.10 inches (384 mm) were recorded in Hokah, which easily broke the old state record of 10.84 inches (275 mm). An unofficial twenty-four-hour total of over 17 inches (432 mm) was recorded near Caledonia. During the entire weekend rainfall event, parts or all of 28 counties in Minnesota received at least 4 inches (102 mm) of rain. The highest total for the entire event was 18.17 inches (462 mm) near La Crescent.{{cite web |archive-url = https://web.archive.org/web/20110526085858/http://climate.umn.edu/doc/journal/flash_floods/ff070820.htm |archive-date = May 26, 2011 |url-status=dead

Southeast Minnesota and southwestern Wisconsin are in the Driftless Area, which was not covered by the last glaciation, and therefore is not covered by deep layers of glacial till. The soils therefore are thin and less able to retain water; they lie atop porous rock into and through which surface waters can rapidly drain into the water table.{{Cite book | last1 = Ojakangas | first1 = Richard W. | last2 = Matsch | first2 = Charles L.| title = Minnesota's Geology | place= Minneapolis | publisher = University of Minnesota Press | year = 1982 | isbn = 978-0-8166-0953-6

High flood waters on the Middle Branch of the Whitewater River, which runs through Whitewater State Park, destroyed three bridges and damaged campgrounds, bathhouses, a group dining hall, and water and sewer systems in the park. About 500 campers were staying in Whitewater State Park at the time. The park was closed to the public on August 20, 2007, for an indefinite period of time. E. coli bacteria were found in the Rushford's water supply, and residents were urged not to use it until the city's water system could be flushed.

Amtrak train service between Minneapolis and La Crosse, Wisconsin was shut down for a week because of damage to the tracks. Passengers were bussed between the two until repairs could be made. The passenger rail line resumed service on August 27.

State Senator Sharon Erickson Ropes stated after initial flooding, "This is the worst disaster that's hit southeast Minnesota in a lifetime." Four thousand two hundred homes were damaged or destroyed in the state, and seven deaths were reported. Dodge, Fillmore, Houston, Olmsted, Steele, Wabasha, and Winona counties were declared federal disaster areas.

Ohio

The Blanchard River was 7.5 feet (2 m) above flood level in Findlay, the highest level since 1913. A 92-year-old man drowned trying to get to safety after his car became trapped in floodwater near Findlay, where water poured into the downtown area from the Blanchard and its tributary creeks. One hundred thirty inmates were moved from a Hancock County jail. Bucyrus received 9 inches (229 mm) of rain, and several hundred people were evacuated from their homes in Crawford County. Ottawa's Main Street (U.S Route 224) was fully flooded, as were homes and churches for blocks around. Between Findlay and Ottawa, Route 224 was washed out in several spots. The fire department in Ottawa rescued dozens of people from their deluged homes by boat.

Northwest Ohio's most serious flooding was along the Blanchard, though other rivers, including the Auglaize, Tiffin, Portage, and Sandusky, all experienced some level of flooding. The cities of Bellevue and Shelby also had severe flooding that forced residents from their homes. Allen, Crawford, Hancock, Hardin, Putnam, Richland, Seneca, and Wyandot counties were declared federal disaster areas.

Wisconsin

In Madison, a mother and daughter waiting for a Madison Metro bus were electrocuted when lightning struck a power line and caused it to fall onto a flooded street on which they were standing, while another child was injured. A passenger on the bus was killed, and the driver was injured, both having been shocked after coming out of the bus to help.

Before this torrential rain and flooding event, much of the state was in a moderate to severe drought that had persisted until mid-August. Although the southern half of the state received abundant precipitation, an upper-level high pressure ridge centered in Quebec caused a cut-off of precipitation to the north, leaving much of northern Wisconsin and Upper Michigan with continued drought conditions.
