Completed in 2005, this earth dam stands at 18 feet high and spans 260 feet in length, with a storage capacity of 20 acre-feet. The dam serves as a key component in managing the flow of Tr-Yeader Creek, a tributary that runs through Polk County.
With a primary purpose of flood risk reduction, Easter Lake Retention Basin #1 is state-regulated by the Iowa Department of Natural Resources. The dam has a significant hazard potential and has been assessed as being in satisfactory condition as of September 2010. Although the dam has not undergone recent inspections or modifications, it is crucial for maintaining the safety and stability of the surrounding area, especially during periods of heavy rainfall and potential flooding events.
While the dam currently meets safety guidelines and moderate risk levels, ongoing monitoring and potential risk management measures will be essential to ensure its continued effectiveness in protecting the community and environment. As a vital piece of infrastructure in the region, Easter Lake Retention Basin #1 serves as a testament to the proactive approach taken by local government to mitigate flood risks and safeguard water resources in the face of changing climatic conditions.
