Lacey Dam, located in Iowa along the TR-Soldier River, was completed in 1961 by the USDA NRCS with a primary purpose of providing fire protection, stock, or a small fish pond. This privately owned earth dam stands at a height of 28 feet and has a storage capacity of 68 acre-feet. With a low hazard potential and a moderate risk assessment rating, the dam is regulated by the Iowa Department of Natural Resources and is subject to state permitting, inspection, and enforcement.

Despite its small size, Lacey Dam plays a vital role in the local ecosystem by providing water storage for fire protection and livestock use. The dam has a surface area of 4 acres and drains an area of 0.86 square miles. Its uncontrolled spillway type and lack of outlet gates indicate a simple design focused on basic water management needs. Although its condition assessment is currently listed as "Not Rated," the dam's risk management measures are in place to ensure its continued safety and functionality.

Lacey Dam's strategic location in Ida County, Iowa, and its association with the Natural Resources Conservation Service make it a notable feature for water resource and climate enthusiasts. With its minimal environmental impact and essential functions for the surrounding community, the dam stands as a testament to responsible water management practices and the importance of maintaining infrastructure for both human and ecological needs.
