Conley Dam, located in Plymouth County, Iowa, was completed in 1975 with a primary purpose of providing fire protection and serving as a small fish pond. Owned and regulated by a private entity, the dam stands at a height of 28 feet and spans 485 feet in length, with a storage capacity of 106 acre-feet. Situated on TR-Mink Creek, the dam plays a crucial role in water resource management in the area, with a low hazard potential and a moderate risk assessment rating.

Managed by the USDA NRCS, Conley Dam is designated as an earth dam with a soil foundation. Despite not having an official condition assessment rating, the dam is considered to be in satisfactory condition and is regularly inspected by the Iowa DNR. The surrounding area enjoys the benefits of the dam's presence, including a surface area of 6 acres and a drainage area of 0.45 square miles. The dam's uncontrolled spillway and lack of outlet gates add to its simplicity and efficiency in water management.

With its strategic location and well-maintained structure, the dam continues to play a significant role in water conservation and climate resilience efforts in Plymouth County, Iowa.
