E&H Farms Dam, located in Jefferson, Iowa, is a privately owned structure designed by USDA NRCS and regulated by the Iowa DNR. Completed in 1988, this earth dam stands at a height of 34 feet and spans 280 feet in length. With a primary purpose of fire protection, stock, or small fish pond, the dam provides a storage capacity of 58 acre-feet and covers a surface area of 4.4 acres.

The dam's low hazard potential and moderate risk assessment make it a crucial component for water resource management in the area. Despite not being currently rated for condition assessment, the dam's construction and design by the Natural Resources Conservation Service ensure its stability and functionality. The presence of an uncontrolled spillway adds an extra layer of safety in case of high water levels, further mitigating any potential risks associated with the structure.

E&H Farms Dam serves as a valuable asset for the local community by providing essential water storage and protection benefits. Its strategic location near Big Cedar Creek and Troy Creek demonstrates its importance for maintaining water resources and climate resilience in the region. As a privately owned and state-regulated structure, the dam plays a significant role in supporting agricultural activities and ecological conservation efforts in Jefferson County, Iowa.
