IFC stream sensor used to track flooding on the Poudre River

The Iowa Flood Center’s stream monitoring network is gaining interest across the country.

Through a partnership with Riverside Technology Inc., the Iowa Flood Center received funding and support to deploy a stream stage sensor on the Poudre River in Colorado. The sensor has been deployed as part of a pilot project to improve flood awareness and prediction capabilities.

New! IFIS Automatic Text Alerts

By Mikael Mulugeta

A new Iowa Flood Information System (IFIS) service now available will change how Iowans receive important flooding alerts.

The new automated alert feature, accessible from the front page of IFIS, allows users to receive IFIS alerts via text message, phone call, or social media when sensors record certain flood levels. Users can select an IFIS sensor of interest, define the criteria for an alert, and then choose a corresponding action.

For example, users can select a sensor in Cedar Rapids and set 15 feet as the minimum stage height to trigger an alert; and have IFIS text parents or other family members a customized message alerting them of the flood warning.

IFIS integration with the IFTTT (If This Then That) website, an automated workflow system, makes this feature possible. Users can set up alerts by following instructions on the IFIS page, setting their conditions and corresponding actions, and then logging on to IFTTT through Google or Facebook accounts to complete the sign up. Find instructions on setting up the automated feature, here.

In addition to smartphones, tablets, and desktops, IFIS can also send alerts to smart devices, such as GE home appliances.

Currently, users can only set alerts to exact values, such as 20 feet of flooding or higher. Moving forward, Iowa Flood Center researchers plan to add categorical flood levels, so alerts will activate if sensors detect “major” or “minor” flooding.


Thoughts go out to Harvey flood victims

Our thoughts and deepest sympathies are with those impacted by the devastating floods caused by Hurricane Harvey.

Iowans remember the 2008 floods that wreaked havoc across our state. Through the chaos, we came together and built back a more resilient Iowa.

Making a Difference for the River

By Jackie Stolze

According to IIHR’s Dan Ceynar, a dedicated river clean-up volunteer, Project AWARE (A Watershed Awareness River Expedition) is like RAGBRAI on the river – minus the partying.

It must have been an amazing sight—dozens and dozens of canoes floating down the Upper Cedar River. Every now and then, one of the volunteers would yell, “Stop! I see a tire!” Then forward progress would halt; they’d splash out into the water and begin the laborious process of excavating the tire and loading it onto the canoe.

The Iowa Department of Natural Resources (IDNR) sponsors this week-long canoe-based river clean-up project every summer in July. Project AWARE moves to a different Iowa river each year, bringing hundreds of volunteers eager to pull out the stuff that shouldn’t be there.

This year, IIHR and the Iowa Flood Center (longtime Project AWARE co-sponsors) sent more than a dozen staff and students to Northeast Iowa to join in the clean-up for one day. Many were first-timers; some had never canoed before. Despite blistering heat and humidity earlier in the week, the IIHR crew was blessed with a beautiful Iowa summer day. The water was remarkably clear and fairly shallow most of the time—very inviting for anyone who wanted to cool off with a quick dip.

It was also incredibly rewarding, says IIHR’s Ashlee Johannes. “The whole day felt magical, and I am so glad to work at IIHR, which fully supports this for its employees.” She and her canoe partner, Breanna Shea, “punched their ticket” by wrestling a tire out of the water—one of 368 tires Project AWARE volunteers removed from the river over the week.

The IDNR organizes and operates the event so smoothly that participants have very little to worry about. “They made the whole experience very fun and stress-free,” says Shea.

Toward the end of the 12-mile paddling trip, the volunteers came across a decades-old garbage dump that included farm machinery, tractor tires, pots and pans, and more — some of it massive and encased in tons of mud. Canoes clustered around the dump and volunteers jumped out into the water, which was hiding barbed wire and other sharp rusty metal garbage. IGS Geologist Ryan Clark says he and his canoe partner pulled out a pile of metal that was most likely an old corn picker.

“The whole side of the river bank was covered with trash,” says Blake Rupe. One by one, the canoers wrestled the junk that could be moved free and loaded it into the canoes. Sometimes it took two canoes tied together to accommodate the larger trash, such as a gigantic tractor tire. Ceynar cut flaps in the tire so he, Clark, and others could scoop out hundreds of pounds of mud before loading the tire onto the double canoe, which he calls a “canoe-maran.”

“The best feeling was getting out of the canoe and watching the volunteers empty out our trash,” says Rupe. “It didn’t feel like much work, but we made a huge difference.”

They really did make a difference, according to statistics gathered by the IDNR: 469 volunteers (ranging in age from 2 to 77) removed 28 tons of trash over the course of the week, including 14.9 tons of scrap metal and 2.5 tons of recyclables.

Rupe says she’s already looking forward to next year. “It really felt like you were making a difference,” she says. Ceynar, Clark, and many others will likely be there too. “I’m not stopping anytime soon!” Clark says. He likes “working hard, getting wet and muddy with friends and strangers, and then feeling the sense of accomplishment when the week is done.”

Be Ready for Spring Floods

The Iowa Flood Center (IFC) offers a suite of online tools, the Iowa Flood Information System (IFIS), that allows all Iowans to access the latest community-based flood information. IFIS is a user-friendly online application based on a Google Maps interface. To launch IFIS, visit

New for 2017, IFIS offers a more responsive design. New features include a community flood map widget that allows website owners to add a customizable IFIS widget to their site. IFIS users can also download the IFIS app to their smartphone or tablet for fast, convenient, real-time data (view download instructions here). In addition, IFIS users can sign up to receive a text with current flood conditions from a specific stream-stage sensor close to their home or business.

IFIS displays up-to-the-minute community-specific information on rainfall, stream levels, and more, including:

  • Current flood warnings and stream forecasts
  • Real-time rainfall maps displaying current conditions and past rainfall accumulations
  • Real-time and historical data on stream levels
  • 2D and 3D interactive visualizations

IFIS also provides flood inundation maps for 22 flood-prone communities across Iowa. These maps allow users to see what a forecasted flood crest would mean for their home or business. Maps are available for Ames, Cedar Rapids, Charles City, Columbus Junction, Des Moines, Elkader, Hills, Humboldt, Independence, Iowa City, Kalona, Maquoketa, Mason City, Monticello, Ottumwa, Red Oak, Rock Rapids, Rock Valley, Spencer, and Waterloo/Cedar Falls, Waverly. IFC researchers continue to develop flood inundation maps for more Iowa communities every year, including at least four new maps this year for Clarksville, Ida Grove, and Fort Dodge.

IFIS helps Iowans make better-informed decisions on flood planning and mitigation efforts and alerts communities in advance to help them prepare for and minimize potential flood damage. Watershed management authority groups across the state can also use IFIS to assist with conservation planning to improve soil and reduce flood risk and to protect people and infrastructure.

The Iowa Legislature established the Iowa Flood Center at the University of Iowa in 2009 to provide accurate, science-based information to help Iowans better understand their flood risks. It is the nation’s first academic center devoted solely to the study of floods. For more information, visit
