It is hard to believe we have reached the end of the Iowa Watershed Approach (IWA).  Many positive impacts to people and our landscape have been achieved, leaving a lasting impression for generations to come. All involved with IWA should feel extremely proud; I thank you for your dedication, commitment, and passion to this program to ensure its success. Through our collective efforts, we navigated a complex administrative system to achieve a more flood-resilient landscape and communities, all while experiencing major flooding and a global pandemic. Together, we have earned state and nationally-recognized awards, and Iowa continues to be a standout and leader in the nation for flood resilience.

Foremost, I feel most proud of the increased watershed literacy across our state. The more educated we are about our water resource challenges, the better our decision-making becomes, the more opportunities develop, and positive action occurs. Our IIHR and Iowa Flood Center teams are committed to staying engaged and serving as technical resources for WMAs far beyond IWA. Please do not hesitate to reach out to one of our team members for questions or requests.

Secondly, the WMAs and their coordinators were the backbone of this program. WMAs are the most critical initiative for inter-local government collaboration working to address flood and water quality concerns. WMAs have gained momentum, built trusting relationships, and made significant investments. However, many water resources challenges remain. We must continue to seek real, reliable, sustainable funding for locally-led WMAs if we expect the legacy of IWA to continue having a positive impact on our state’s water resources.

Our work is far from complete. We have a responsibility to the next generation to develop sustainable policy changes that reflect the actual and future risks that many people are experiencing.  Together, we can maintain a strong agricultural economy while protecting our water and natural resources, and creating an environment where people are drawn to live, work and recreate.

John Rathbun displays watershed award

ANKENY, IOWA – John Rathbun, watershed coordinator for the Clear Creek Watershed, is honored with a Circle of Excellence award from the Iowa Agriculture Water Alliance (IAWA) as part of the third annual Iowa Watershed Awards program.

Rathbun is honored with five other watershed coordinators who are also receiving IAWA Iowa Watershed Awards for their multitude of contributions and steadfast dedication to improving water quality across the state.

“With Earth Day on April 22nd, it’s a great time to recognize watershed coordinators — the unsung local heroes who work hard every day to implement conservation practices to improve water quality,” says Sean McMahon, IAWA Executive Director. “John is helping farmers and landowners meet local community goals while also simultaneously advancing the objectives of the statewide Iowa Nutrient Reduction Strategy.”

Improving Water Quality with Flood Control

“That’s when I was first introduced to green infrastructure in terms of rain gardens, bioswales, and permeable patios and paving,” he says. “That really spurred my interest in water quality and quantity as well.”

Today, his work in the Clear Creek Watershed focuses on rural areas. About 35,000 of the watershed’s 66,000 acres are in row crops. Clear Creek starts in the farming areas north of the Williamsburg outlet mall and empties into the Iowa River in Coralville.

The main goal of the project, funded with a Department of Housing and Urban Development grant, is flood control in Coralville and other communities. “It helps the rural folks too if we save some intersection at a road crossing from washing out,” Rathbun says.

Preliminary plans are done for about half of more than 70 planned flood mitigation practices that include ponds, wetlands, oxbows, water and sediment control basins, and terraces. About $3 million will be spent on project construction over the next year and a half. The goal is to complete the project in 2021.

“The most rewarding part has been working with the landowners and walking over their land with them and hearing how they look forward to passing it on to future generations,” Rathbun says. Some have told him that they’ve dreamed since childhood of having a pond on their land.

“Most of the flood control projects have water quality aspects as well,” he says. Ponds and wetlands denitrify water and sediment settles out in them.

“They think ponds are close to having the same denitrifying effects as wetlands,” he adds.

At two locations in the watershed, the University of Iowa measures nitrate concentration and several other indicators of quality as well as discharge rates.

Rathbun’s many partners in the Clear Creek Watershed include The Natural Resources Conservation Service, Johnson County, the East Central Iowa Council of Governments, the Iowa Flood Center, Iowa State University Extension and Outreach, Iowa Department of Natural Resources (DNR), Iowa Department of Agriculture and Land Stewardship (IDALS), Iowa Economic Development Authority, and Iowa Department of Homeland Security.

“Local leaders I work with include those with Johnson County Conservation who sit on our technical committee,” he says. “Our Water Management Association board is very involved. The Mayor of Coralville, John Lundell, and Iowa County Supervisor John Gahring, have given me great support and helped trouble shoot when they can.”

The project is part of the Iowa Watershed Approach,  

To help maintain momentum for this work, Rathbun will receive funding through the Iowa Watershed Award to apply to the Clear Creek Water Quality Project as well as funding for his own professional development.

IAWA developed the Iowa Watershed Awards program with Iowa State University Extension and Outreach, Conservation Districts of Iowa, IDALS, and Iowa DNR.

The Iowa Agriculture Water Alliance (IAWA) is increasing the pace and scale of farmer-led efforts to improve water quality in Iowa. Founded in 2014 by Iowa Corn, the Iowa Soybean Association, and the Iowa Pork Producers Association, IAWA is building public-private partnerships focused on implementing water quality solutions.

Mark Kennett and wife in New Zealand

Over time, both New Zealand and Iowa have moved from their native ecology to a more intensively managed, agriculture-based ecosystem. In New Zealand, the water ran clear as recently as 20 years ago, whereas in Iowa, environmental challenges date back more than a generation. Mark Kennett was born in New Zealand but moved to the United States with his wife after completing school.

They both come from farming families — Kennett’s in New Zealand and his wife’s in Iowa. Together, they now run her family farm in Poweshiek County a few miles outside of Grinnell. After living most of his life as a farmer in these two locations, Kennett has a unique perspective on the changes he has witnessed.

Kennett does his part to make sure he is heard in the community, serving on at least six separate boards representing his county and personal interests. Kennett says it’s the neighborly thing to do because in a small, rural community, finding people to take on leadership positions can be difficult.

“People are busy, and it takes a lot of involvement to satisfy all the county government roles that need to be executed,” Kennett says.

Kennett has been an active member of the English River Watershed Management Authority board since its creation in 2013. On this board, he represents the Poweshiek County Soil and Water Conservation District. He saw the value in creating a group dedicated to connecting communities along the same body of water. Generally, the fate of water is unknown once it passes over county lines simply because counties do not discuss their shared waterway.

Kennett saw the position as a way to open up lines of discussion between the people who rely so heavily on a shared water source. He stresses the importance of keeping everyone’s interests in mind, especially when they make an effort to voice an opinion. He especially enjoys interacting with the young adults because when young people get involved in politics, they can help shape their own futures.

Kennett found that life in a relatively small watershed makes everyone more aware of the consequences of water-quality and water-quantity issues. While Poweshiek County sat dry at the top of the hill, excess water flowed away down into Kalona and Riverside, affecting the communities in a direct and visible way. Open lines of communication between the communities allows the towns to discuss the issues and work toward a common goal of reducing flood impacts.

“We’re very fortunate in the English that it’s relatively small. We see the top of it and the lower reaches of the watershed, and the performance of one helps or hinders the other,” Kennett says.

Water quality is quickly becoming an important issue in today’s political mainstream, with agriculture typically taking the brunt of the criticism. As a farmer, Kennett has a first-hand perspective on the issue. New technology designed and tested in New Zealand to measure nitrates in the soil will soon be available with the hope that it can reduce nutrient loss from the fields. Kennett is hopeful that technology such as this can help farmers while also improving water quality.

Moving forward, Kennett hopes Iowans will treat water sources with more respect. He believes a focus on the benefits of water will create a culture that protects natural resources rather than simply using them as a waste elimination tool. New Zealand puts time and energy into water recreation, something Iowa lacks. Policy, technology, and young adults are vital to change the culture around water in Iowa moving forward.

When Angie Auel asked the fifth graders of Fairbank Elementary School about water retention issues in their community, they told her about their basketball court. Whenever rain or snow falls on the court, they said, the space floods, leaving them without a place to play. Auel, with the help of the kids, created a plan to build a rain garden next to the basketball court to capture the runoff and keep the court dry.

Auel is the project manager for the Upper Wapsipinicon River Watershed (also called the Upper Wapsi), which encompasses a large stretch of northeastern Iowa. The Upper Wapsi is one of the nine Iowa watersheds that are part of the Iowa Watershed Approach (IWA), a project focused on flood management and resilience.

As an IWA watershed coordinator for the Upper Wapsi Watershed, Auel works closely with the community. Lately, she has focused on educating fifth graders on stormwater management, including students in Readlyn, Iowa. The City of Readlyn is in the process of building a wetland south of town to help contain stormwater runoff and improve water quality as it flows toward the Wapsi River. A teacher at Readlyn elementary received a grant of nearly $5,000 for wetland plants, which the students will plant once school is back in session.

Education is far from the only job Auel does, though she stresses the importance of keeping people involved with the health of the watershed.

“Once the [grant] money is gone, we still want people to be considering what is going on in our watershed, how we can help slow down the water, and not just push it downstream as fast as we can,” she says.

Citizens of Winthrop, another community within the Upper Waspi Watershed, recently received a grant to help install permeable pavers into their streets, a project that Auel will be helping them with. Currently, water runs off rooftops and onto gravel below. The runoff erodes the gravel into the river and on downstream. Runoff can erode river banks, carry dangerous toxins and litter into the rivers, and contaminate drinking water. Permeable pavers offer a solution to runoff by directing the water back into the soil before it can reach the river. The pavers are porous, allowing water to run through the street and into crushed gravel below, which filters the water as it flows into the ground. Water that infiltrates the ground rather than flowing directly into the river is filtered by the soil, removing chemicals that may have been picked up along the way, especially from rooftops.

From a group of fifth graders to the residents of an entire watershed, Angie Auel is constantly teaching people about the health and safety of the water around them.
