Grell Pond Dam, located in Ida County, Iowa, was completed in 1958 by the USDA NRCS and serves multiple purposes including fire protection, stock, and small fish pond. The earth dam stands at 26 feet tall and spans 387 feet in length, with a storage capacity of 109 acre-feet and a surface area of 6.1 acres. The dam is regulated and inspected by the Iowa DNR, with a significant hazard potential and a poor condition assessment as of December 2015.

Despite its age and condition, Grell Pond Dam continues to play a crucial role in water resource management in the area. The dam's location near the TR-MAPLE River provides valuable flood control and water storage capabilities for the surrounding community. However, with a risk assessment rating of moderate, there is a need for ongoing risk management measures to ensure the safety and effectiveness of the dam in the face of changing climate patterns and increasing water resource demands.

As a private-owned structure, Grell Pond Dam is a vital asset for its owners and the local ecosystem. With its historical significance and functional purpose, the dam represents a connection to the past while also highlighting the importance of sustainable water resource management practices in the present day. Climate enthusiasts and water resource experts alike can appreciate the role that Grell Pond Dam plays in protecting the environment and supporting the needs of the community in a changing climate landscape.
