Erickson Dam, located in Harrison, Iowa, along TR-Willow Creek, was completed in 2003 by the NRCS with a primary purpose of flood risk reduction. This private earth dam stands at 27 feet high and spans 520 feet in length, providing a storage capacity of 39 acre-feet for the surrounding area. With a low hazard potential and a moderate risk assessment rating, Erickson Dam plays a crucial role in maintaining the safety and stability of the local watershed.

Despite being privately owned, the dam is subject to state permitting, inspection, and enforcement, ensuring that it meets regulatory standards and operates effectively. The spillway is uncontrolled with a width of 10 feet, allowing for the controlled release of excess water during heavy rainfall events. While the dam's condition assessment is currently listed as "not rated," it continues to serve as a vital infrastructure for flood control and grade stabilization in the region, contributing to the overall resilience of the watershed.

As water resource and climate enthusiasts, the data on Erickson Dam provides valuable insights into the infrastructure that supports flood risk reduction efforts in Iowa. With its strategic location, design specifications, and operational features, Erickson Dam stands as a testament to the collaborative efforts between private owners and regulatory agencies in safeguarding local communities from potential water-related disasters.
