Warner Dam, located in Wapello, Iowa, is a private-owned structure designed by USDA NRCS with a primary purpose of fire protection, stock, or small fish pond. Completed in 1989, this earth dam stands at a height of 35 feet and spans a length of 395 feet, creating a reservoir with a storage capacity of 23 acre-feet. Situated on TR-PALESTINE CREEK, the dam serves as a vital water resource for the surrounding area, providing essential benefits for both wildlife and local communities.

Despite its low hazard potential and moderate risk assessment, Warner Dam is regulated and inspected by the Iowa Department of Natural Resources to ensure its structural integrity and safety. The dam's spillway type is uncontrolled, and it has not been modified since its completion. While the dam's condition is currently not rated, its emergency action plan (EAP) status and risk management measures remain unspecified. With its critical role in water management and conservation, Warner Dam represents a valuable asset for water resource and climate enthusiasts to study and monitor for sustainable utilization and environmental protection in the region.
