This Earth dam, built in 1971 by the USDA NRCS, serves multiple purposes including fire protection, stock, small fish pond, flood risk reduction, and recreation. With a height of 44 feet and a length of 376 feet, this dam stores 89 acre-feet of water in its reservoir, covering a surface area of 4 acres and draining a 0.43 square mile watershed.
Located in the TR-Boyer River watershed, this dam has a low hazard potential and is currently not rated for its overall condition. However, it meets state permitting, inspection, and enforcement requirements by the Iowa DNR. The risk assessment for this structure is moderate, with a DSAC assigned date yet to be determined. Although the dam has not been modified in recent years, it is crucial for water management in the region and warrants close monitoring and potential risk management measures in the future to ensure its continued safety and functionality for the community.
