Brantley Dam, located in Lucas County, Iowa, was completed in 1979 and is primarily used for fire protection, stock, or as a small fish pond. The dam stands at 35 feet high and spans a length of 290 feet, with a storage capacity of 52 acre-feet. It is classified as an earth dam with a soil foundation and is regulated by the Iowa Department of Natural Resources.

The dam is situated on TR-Mill Branch Creek and serves as a crucial water resource for the surrounding area. Despite its low hazard potential and moderate risk assessment, the dam is not currently rated for its condition. It is owned privately and falls under the jurisdiction of the state, with regular inspections and enforcement conducted by the Iowa DNR to ensure its safety and functionality.

With its strategic location and important role in providing water for various purposes, Brantley Dam is a key feature in the local landscape. Water resource and climate enthusiasts can appreciate the efforts of the USDA NRCS in designing and maintaining this vital infrastructure, which contributes to the resilience and sustainability of the region's water supply.
