If you’ve been to an Iowa county fair or attended an Iowa State University (ISU) extension field day covering water quality, conservation, cover crops, edge of field practices or a range of other topics, there’s a good chance you’ve seen or even visited a Conservation Station operated by Water Rocks! and Iowa Learning Farms. Last summer we hit the milestone of attending all 100 county fairs in Iowa – (yes 100, Pottawattamie County holds two.) The trailers also make appearances at community events, farmer’s markets and other settings.
The Conservation Stations are traveling resource centers and classrooms, staffed by ILF and Water Rocks! team members and interns, providing water quality and conservation education and outreach activities built on a foundation of science, research and best practices. These events also provide great learning opportunities for the team to sharpen trailer pulling and backing skills.
Rain, Rain, Don’t Wash our Soil Away
The idea for the first Conservation Station was germinated in the early years of Iowa Learning Farms (ILF) – which is celebrating 15 years in 2019. The precursor was a trailer equipped with a simple rainfall simulator for demonstrating soil erosion.
It was a good start, but frankly, it was a limited demonstration and the team quickly realized that they needed a more sophisticated rainfall simulator. In addition, ILF saw the potential to expand its impact by providing a broad canvas for education through visual, interactive and multimedia displays.
“We were awarded funding to purchase and develop a larger trailer and knew how to make a better rainfall simulator,” said Jacqueline Comito, executive director of Water Rocks! and ILF program director. “We just didn’t know how to realize our vision of a traveling and flexible unit. Ann Staudt joined the team to help us, and with her fresh ideas and creativity, the Conservation Station was born.”
The trailer, dubbed the Big Conservation Station, allowed space for an improved rainfall simulator as well as a walk-through learning lab. To facilitate use in different environments such as field days, outdoor classrooms and county fairs, the trailer accommodates interchangeable displays. Inside the learning lab, visual and multimedia presentations are designed to engage audiences in conversations and to elicit questions about conservation practices.
The learning lab was updated in 2018 to incorporate mixed-media artwork and enhanced messaging with the purpose of eliciting visitors’ hopes for Iowa.
ILF faculty adviser Matthew Helmers developed the new rainfall simulator which more accurately models both surface runoff and subsurface flow or drainage in tiled environments and uses soil blocks extracted from field environments to best parallel actual soil conditions in Iowa fields.
“The complexity of the new rainfall simulator was a challenge, but it also enabled us to tell a much more realistic story that farmers in Iowa could relate to,” noted Staudt.
A smaller trailer referred to as Conservation Station 3 was built specifically for outdoor classrooms and other youth activities. Along with a rainfall simulator, it is also equipped with the space to carry enough tables and chairs for students as well as a full complement of displays and activity resources.
Edge of Field Practice Demonstrations Expand Education Opportunities
In 2018, the original rainfall simulator trailer (which we called the Lil’ CS) was redesigned to become the Conservation Station on the Edge, addressing best practices for nutrient mitigation at the edge of tile-drained fields. Equipped with working saturated buffer and bioreactor models, this trailer takes the story of nutrient reduction to a deeper level. The demonstration stations allow the audience to see what happens within structures –that when implemented in a field are completely underground and out of sight.
Each Conservation Station includes interactive demonstrations that appeal to all backgrounds, ages and walks of life. Games such as the Poo Toss tend to appeal to youngsters but provide tangible lessons about waste runoff that pertains to everyone –whether they live on a farm or in a city. The Watershed Game is another highly visual interactive game that helps make the concepts of a watershed and how pollution moves with water easy to grasp.
“The Conservation Stations are filling a tremendous need by providing easy-to-understand information about water quality, conservation, agricultural best practices, and other topics of importance to all Iowans,” concluded Staudt. “We intend to continue to share this knowledge as frequently and in as many venues as we can.”

The Conservation Stations are used April through October. Check out the Water Rocks! website to request a visit (requests for summer events are being accepted now!). In most circumstances, a Conservation Station can join an event at no cost, due to the generous funding received from our partners.
