New Maps Aid in Flood Management

,

Urbana, Iowa — Scientists from the University of Iowa are conducting new mapping of the ground beneath our feet in the Middle Cedar Watershed. Yesterday, watershed stakeholders met in a rural area southwest of Urbana to catch a glimpse of the action and learn about the importance of geologic mapping for landowners, farmers, private industry, land use planners, and urban and rural community members. Phillip Kerr, a geologist with the Iowa Geological Survey (IGS) said, “This mapping is critical to our efforts to solve earth science problems — the information we collect will be used to address a variety of problems related to development, growing population needs, and the vulnerability of groundwater, as well as flood management.”

IGS geologists at the University of Iowa participate in the STATEMAP program, funded by the United States Geological Survey (USGS). The program provides funding to states to conduct detailed geologic mapping with an emphasis on solving environmental issues. This type of mapping helps Iowans understand what’s beneath the Earth’s surface, and how local geology affects their day-to-day lives.

Besides providing vital information for landowners, agriculture and natural resource businesses, and researchers, this subsurface mapping also supports planning and construction activities for the $97M Iowa Watershed Approach (IWA), a statewide program focused on reducing flood risk in nine watersheds across Iowa, including the Middle Cedar Watershed.  In 2013, the Iowa Nutrient Reduction Strategy identified the Middle Cedar as a priority watershed.  In 2016, local residents formed the Middle Cedar Watershed Management Authority (WMA) to bring partners together to address watershed concerns.  Areas of the Middle Cedar, especially near Vinton, are vulnerable to and at higher risk of flooding and groundwater variability. This mapping will aid in planning and land use decision-making for this area for flood management. In addition, it will help the IWA to identify priority areas for conservation best management practices, such as ponds and wetlands, with flood storage capabilities.

Funding is available for landowners in select areas of the watershed to construct a variety of conservation practices designed to reduce flooding and improve water quality. Participation in the IWA is entirely voluntary for landowners, who get a 90% cost share if they choose to build a conservation practice such as a farm pond on their property.

Flood Reduction Practices Eligible for 90 Percent Cost Share

,

Through the Iowa Watershed Approach statewide program, qualifying landowners can receive up to 90 percent cost-share assistance to implement small-scale flood mitigation practices.

Across the state, the Iowa Watershed Approach (IWA) is working with landowners and other stakeholders to implement watershed projects to reduce flooding and improve water quality. The program focuses on nine watersheds (Dubuque/Bee Branch, Upper Iowa, Upper Wapsi, Middle Cedar, English River, Clear Creek, East Nishnabotna, West Nishnabotna, and North Raccoon).

Local stakeholders and volunteer landowners within the qualifying areas will be considered for 90 percent cost-share assistance to implement in-field and edge-of-field conservation practices that offer flood reduction and water-quality improvement benefits. Eligible conservation practices include, but are not limited to, the following:

  • Wetlands
  • Farm ponds
  • Stormwater detention basins
  • Terraces
  • Sediment detention basins
  • Floodplain restoration
  • Channel bank stabilization
  • Buffer strips
  • Saturated buffers
  • Perennial cover
  • Oxbow restoration
  • Bioreactors
  • Prairie STRIPS

The 90 percent cost share is a recent increase from the original 75 percent. The landowner will cover the remaining 10 percent or through local match. Conservation practices will meet all NRCS specifications and guidelines. For more information, contact Kate Giannini at kate-giannini@uiowa.edu or 319-335-5233

The IWA is a five-year project to minimize flood risk in Iowa that began in 2016. This approach builds upon other Iowa programs designed to reduce flooding and improve water quality, such as the Iowa Flood Mitigation Program and the Iowa Nutrient Reduction Strategy.

The Iowa Watershed Approach is a $97M statewide program funded by the U.S. Department of Housing and Urban Development. The success of the IWA depends on collaborative partnerships among many statewide organizations and local stakeholders who together will carry out the work necessary to achieve the program goals. Partners include, but are not limited to: Iowa Economic Development Authority; Homeland Security and Emergency Management; University of Iowa; Iowa State University; University of Northern Iowa; Iowa Department of Natural Resources; Iowa Department of Agriculture and Land Stewardship; cities of Coralville, Dubuque, and Storm Lake; and many Iowa counties.

Touring the Otter Creek Watershed

,

Despite a rainy start to the day, nearly 60 people gathered for a bus tour of the Otter Creek Watershed in Northeast Iowa on June 8. Participants saw rural and urban conservation practices designed and installed to reduce flooding in the watershed.

The tour began and ended in West Union, Iowa, where downtown infrastructure has been upgraded to enhance stormwater management. This project includes more than four acres of permeable pavers for downtown streets and sidewalks placed over a bed of crushed stone. This system has the capacity to manage a hundred-year storm, with no discharge for rainfall events between 0.5–0.75 inches.

The first stop of the morning was a large on-road structure east of West Union, one of five built in the Otter Creek Watershed as part of the recently completed Iowa Watersheds Project. This baffle-type installation on a roadway culvert impounds water upstream of the roadway, slowing runoff. Fayette County Engineer Joel D. Fantz told the group that this type of structure is a win-win for taxpayers, landowners, and residents of the county.

Next up, participants saw two farm ponds, which can reduce flood damage by storing water during high runoff periods. Ponds hold back floodwaters temporarily and release the water at a slower rate, lowering peak flood discharge downstream and supporting soil conservation efforts. Landowner and Turkey River Watershed Management Authority (WMA) board vice-chair Bill Bennett told the crowd, “If we can capture the water where it falls, we’ll be much better off.”

Downtown Elgin, set at the confluence of Otter Creek and the Turkey River, recently completed a downtown revitalization project that incorporated permeable pavers into parking areas on either side of the city’s main street. Two riparian wetlands also provide storage for stormwater runoff.

After an amazing lunch at the Brick City Bar and Grill in Elgin (provided by Fehr Graham Engineering, Turkey River WMA, and the Fayette County Soil and Water Conservation District), it was back on the bus for a ride to the Rush Prairie Wildlife Sanctuary near West Union. The 234-acre sanctuary includes almost 90 acres of native prairie, more than 40 acres of buffer strips, and 103 acres of tillable land. It has never been tiled and contains one of the largest remaining prairie parcels in Fayette County. The property provides wildlife habitat, botanical diversity, and water-quality benefits to the watershed.

Sponsors for the Otter Creek Watershed Tour included: Iowa Flood Center, Turkey River WMA, Fayette County Conservation Board, Fayette County Board of Supervisors, Fayette County Soil and Water Conservation District, Northeast Iowa Resource Conservation and Development, Fehr Graham Engineering & Environmental, and Brick City Bar and Grill.

IFC Hydro Stations Provide Weather Data Farmers Need

, ,

For farmers, timely information is vital. The Iowa Flood Center (IFC) at the University of Iowa is deploying new hydrologic stations that provide real-time weather information that farmers can use. The stations measure rainfall, wind speed and direction, and soil moisture and temperature. A shallow groundwater well also provides information about the water table. And the IFC makes all the data publicly available on the internet.

Father and son Stewart and Jared Maas farm about 1,800 acres 25 miles west of Iowa City. Their home farm is the site of one of the new IFC hydrologic stations. “We try to do everything the right way,” Jared explains, and data collected by the IFC hydro station can help. As Stewart and Jared prepare for spring fieldwork, they can check the online sensor data to learn when the soil is ready to plant, the best time for field applications, and how to plan for changing weather conditions.

“It helps a lot,” Stewart says. One example is the application of fertilizer in the fall. Farmers are encouraged to wait until soil temperatures are 50 degrees F or colder to limit nitrogen loss. Stewart and Jared now have facts on which to base their decisions — a real advantage for big operations like theirs. For Stewart and Jared, the data provide peace of mind that they’re doing things “the right way.”

Stewart has been working with University of Iowa researchers for years. “The university has been really good to us here,” Stewart says. “I’ve got a lot of respect for the hydrology department.”

IIHR Research Engineer, Jim Niemeier, explains the data the hydro station collects

Besides providing vital information for agriculture, sensor data also support IFC activities for the $97M Iowa Watershed Approach (IWA) statewide program focused on reducing flood risk in nine watersheds across Iowa. The Maas farm is in the Clear Creek Watershed, which is part of the IWA. John Rathbun, project coordinator for the Clear Creek Watershed, says that interest in the IWA is growing among landowners in the basin. “It’s really all about building relationships,” he explains. Participation in the IWA is entirely voluntary for landowners, and farmers get a 75% cost share if they choose to build a conservation practice such as a farm pond on their property.

With funding from the IWA, the IFC will deploy a network of 20 hydrologic stations this year. The new sensors represent an expansion of the IFC’s current network of nearly 50 similar rain gauge stations statewide. This growing network of hydrologic stations is helping the IFC reach its goal of 100 stations deployed in Iowa—one in each county. This network will help researchers and stakeholders better predict floods, assess droughts, and manage water resources. In addition, Iowa’s farmers can use the information to support their crop management systems and potentially boost yields.

The Iowa Flood Information System (IFIS) online tool provides real-time information on watersheds, precipitation, and stream levels for more than 1,000 Iowa communities. Data collected from the hydrologic stations can be accessed at ifis.iowafloodcenter.org/ifis/app.

“Farming doesn’t pay very well,” says Stewart. But, he adds, “It makes farming fun, getting involved in some of these things.”
