Smith Dam, located in Cherokee, Iowa, along the TR- Little Sioux River, was completed in 1996 by the USDA NRCS and serves multiple purposes including fire protection, stock, and small fish pond management. The earth dam stands at 42 feet in height and spans 300 feet in length, with a maximum storage capacity of 92 acre-feet and a normal storage capacity of 34 acre-feet. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.

Managed by a private owner, Smith Dam is regulated by the Iowa DNR and undergoes regular inspections, permitting, and enforcement to ensure safety and compliance. The dam's spillway type is uncontrolled, with no outlet gates or associated structures. Despite its moderate risk assessment rating, the dam has not had an emergency action plan prepared or updated recently. With a surface area of 3.8 acres and a drainage area of 0.73 square miles, Smith Dam provides essential water resource management for the local community while maintaining a low hazard potential.
