In 2008, separate flood events occurred in the Midwest in January, February, March, April, May, June, July, and September.

Within the Iowa River Basin, peak discharges of 51,000 cubic feet per second (flood-probability estimate of 0.2 to 1 percent) at the 05453100 Iowa River at Marengo, Iowa streamflow-gaging station (streamgage) on June 12, and of 39,900 cubic feet per second (flood-probability estimate of 0.2 to 1 percent) at the 05453520 Iowa River below Coralville Dam near Coralville, Iowa streamgage on June 15 are the largest floods on record for those sites. A peak discharge of 41,100 cubic feet per second (flood-probability estimate of 0.2 to 1 percent) on June 15 at the 05454500 Iowa River at Iowa City, Iowa streamgage is the fourth highest on record, but is the largest flood since regulation by the Coralville Dam began in 1958. Within the Cedar River Basin, the May 30 to June 15, 2008, flood is the largest on record at all six streamgages in Iowa located on the mainstem of the Cedar River and at five streamgages located on the major tributaries.

In June 2008, the rivers of eastern Iowa rose above their banks to create floods of epic proportions; their amazing size—flowing in places at a rate nearly double that of the previous record flood—and the rapidity of their rise ruined farmlands and displaced thousands of residents and hundreds of businesses. In Cedar Rapids, the waters inundated more than nine square miles of the downtown area; in Iowa City, where the flood was also the most destructive in history, the University of Iowa’s arts campus was destroyed. By providing a solid base of scientific and technical information presented with unusual clarity and a wealth of supporting illustrations, the contributors to this far-reaching book, many of whom dealt firsthand with the 2008 floods, provide a detailed roadmap of the causes and effects of future devastating floods. The twenty-five essays fall naturally into four sections. “Rising Rivers, Spreading Waters” begins by comparing the 2008 floods with the midwestern floods of 1993, moves on to trace community responses to the 2008 floods, and ends by illuminating techniques for forecasting floods and determining their size and frequency. “Why Here, Why Now?” searches for possible causes of the 2008 floods and of flooding in general: annual crops and urban landscapes, inflows into and releases from reservoirs, and climate change. “Flood Damages, Flood Costs, Flood Benefits” considers the complex mix of flood costs and effects, emphasizing damages to cities and farmlands as well as potential benefits to natural communities and archaeological sites. “Looking Back, Looking Forward” lays out approaches to managing the floods of the future that are sure to come. While the book draws most of its examples from one particular region, it explains flooding throughout a much larger region—the midwestern Corn Belt—and thus its sobering yet energizing lessons apply well beyond eastern Iowa. By examining the relationships among rivers, floodplains, weather, and modern society; by stressing matters of science and fact rather than social or policy issues; and by addressing multiple environmental problems and benefits, A Watershed Year informs and educates all those who experienced the 2008 floods and all those concerned with the larger causes of flooding.

"This report is part of an ongoing program that is publishing flood profiles of streams in Iowa. The program is managed by the U.S. Geological Survey in cooperation with the Iowa Department of Transportation and the Iowa Highway Research Board (Project HR-140). Information from flood profiles is used by engineers to analyze and design bridges, culverts, and roadways. This report summarizes 47 U.S. Geological Survey flood-profile reports that were published for streams in Iowa during a 50-year period from 1963 to 2012. Flood events profiled in the reports range from 1903 to 2010. Streams in Iowa that have been selected for the preparation of flood-profile reports typically have drainage areas of 100 square miles or greater, and the documented flood events have annual exceedance probabilities of less than 2 to 4 percent. This report summarizes flood-profile measurements, changes in flood-profile report content throughout the years, streams that were profiled in the reports, the occurrence of flood events profiled, and annual exceedance-probability estimates of observed flood events. To develop flood profiles for selected flood events for selected stream reaches, the U.S. Geological Survey measured high-water marks and river miles at selected locations. A total of 94 stream reaches have been profiled in U.S. Geological Survey flood-profile reports. Three rivers in Iowa have been profiled along the same stream reach for five different flood events and six rivers in Iowa have been profiled along the same stream reach for four different flood events. Floods were profiled for June flood events for 18 different years, followed by July flood events for 13 years, May flood events for 11 years, and April flood events for 9 years. Most of the flood-profile reports include estimates of annual exceedance probabilities of observed flood events at streamgages located along profiled stream reaches. Comparisons of 179 historic and updated annual exceedance- probability estimates indicate few differences that are considered substantial between the historic and updated estimates for the observed flood events. Overall, precise comparisons for 114 observed flood events indicate that updated annual exceedance probabilities have increased for most of the observed flood events compared to the historic annual exceedance probabilities. Multiple large flood events exceeding the 2-percent annual exceedance-probability discharge estimate occurred at 37 of 98 selected streamgages during 1960-2012. Five large flood events were recorded at two streamgages in Ames during 1990-2010 and four large flood events were recorded at four other streamgages during 1973-2010. Results of Kendall's tau trend-analysis tests for 35 of 37 selected streamgages indicate that a statistically significant trend is not evident for the 1963-2012 period of record; nor is an overall clear positive or negative trend evident for the 37 streamgages."--Abstract, page [1].

Excerpt: The Iowa flood of 2008 was a hydrological event involving most of the rivers in eastern Iowa beginning around June 8, 2008 and ending about July 1. Flooding continued on the Upper Mississippi River in the southeastern portion of the state for several more days. The phrase "Iowa's Katrina" was often heard. The flooding included (from north to south, east to west), the Upper Iowa River, the Turkey, and the Maquoketa Rivers; outside of the Driftless Area, they include the catchments of the Wapsipinicon River and that of the Iowa River, to include the latter's major tributary, the Cedar River (and its significant tributaries); and the Skunk River in its various forks. The Des Moines River had some minor flooding, but floodwalls and levees for the most part held fast. The Upper Mississippi River which receives the outflow from all these rivers remained at flood stage. The flooding of Cedar Rapids and Iowa City were the most significant events. Recovery in particular for Cedar Rapids is considered to be a protracted and costly affair. For Iowa City, the level of damage was less than expected, but that of Cedar Rapids was greater than anticipated. In Iowa City, the campus of the University of Iowa was vulnerable, and serious flooding did...

Flood-elevation profiles and flood-peak discharges for floods during 1972, 1982, and 1987 in the Nishnabotna River basin are given in the report. The profiles are for the 1972 flood on the West and East Nishnabotna Rivers, the 1982 flood on Indian Creek, and the 1987 flood on the lower West Nishnabotna River. A flood history describes rainfall conditions and reported damages for floods occurring 1947, 1958, 1972, 1982, and 1987. Discharge for the 1982 flood on Indian Creek is 1.1 times larger than the 100-year recurrence interval discharge.
