Dry Run Creek Designed to Prevent Floods
Waverly, Iowa, is built around the Cedar River which overflowed in the flood of 2008. To prevent such natural disasters in their community, Waverly researched different ways to prevent flooding, such as dry run creeks. Dry run creeks can be found across Bremer County but also in towns and cities across Iowa. They are named dry run creeks because of their specific design. Their purpose is to help prevent flooding, or other natural disasters. They are strategically placed, and researched.

Classroom Suggestions
Students could:
- In groups, build dry run creeks out of environmental materials (such as different sized rocks, clay etc.), that can collect and move water.
- Brainstorm and list different traits and characteristics of a dry run creek, and the ecosystems around it. If located in their community, students can consider their local dry run creek.
- Research the placement of dry run creeks around the world and compare and contrast to determine which dry run creek placement might work best.
