Summary
Built in 1942, this earth dam stands at 22 feet tall and spans 550 feet in length, creating a reservoir with a storage capacity of 52 acre-feet. The primary purpose of Smith Lake is for fish and wildlife pond management, as well as recreation for visitors to enjoy the peaceful waters surrounded by the picturesque landscape.
Although the dam is classified as low hazard potential, the risk assessment deems the area as very high risk due to its proximity to the Missouri River tributary. Despite the lack of state jurisdiction and regulation, the US Army diligently handles all aspects of ownership, funding, design, construction, inspection, and operation of Smith Lake. With a controlled spillway and a slide gate for outlet control, the dam ensures the safety and stability of the surrounding ecosystem and community.
Water and climate enthusiasts will find Smith Lake to be an intriguing site for its historical significance, engineering design, and recreational opportunities. As a part of the US Army's portfolio of infrastructure, this reservoir serves as a vital resource for both wildlife and visitors seeking a tranquil environment to appreciate nature's beauty. The continuous monitoring and management of Smith Lake demonstrate a commitment to safeguarding water resources for future generations to enjoy.

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.
