Kistler Dam, located in Jefferson County, Iowa, is a private earth dam built in 1987 by the USDA NRCS for irrigation purposes along Troy Creek. Standing at a height of 15 feet and stretching 530 feet in length, the dam has a storage capacity of 100 acre-feet and covers a surface area of 7.8 acres. Despite its relatively low hazard potential and moderate risk assessment, the dam is regulated by the Iowa Department of Natural Resources and undergoes regular state inspections, permitting, and enforcement to ensure its structural integrity and safety.

The dam's primary purpose is irrigation, with additional functions for fire protection, stock watering, and small fish pond support. It is designed to hold back water using soil foundations and features an uncontrolled spillway. While the dam's condition is currently not rated, its risk management measures are in place to mitigate any potential hazards. The surrounding area, including the Big Cedar Creek community, benefits from the dam's water resource management and agricultural support, highlighting its crucial role in sustaining local ecosystems and livelihoods.

As a key infrastructure for water resource management in the region, Kistler Dam plays a vital role in supporting agricultural activities and ensuring water availability for the surrounding communities. With its low hazard potential and moderate risk assessment, the dam stands as a reliable structure for irrigation purposes along Troy Creek. Ongoing state oversight and inspections further emphasize the importance of maintaining the dam's integrity and safety to safeguard both property and lives in the area.
