Lacey Dam Reservoir Report
Last Updated: December 15, 2025
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.

Summary
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.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
