Summary
This earth dam, completed in 1965, stands at a height of 25 feet and has a storage capacity of 468 acre-feet, with a normal storage level of 292 acre-feet. It covers a surface area of 35 acres and drains a watershed area of 400 acres, playing a vital role in protecting the surrounding communities from potential flooding events.
In addition to flood risk reduction, the City of Lewistown Dam also serves recreational and water supply purposes, showcasing its multifaceted importance to the region. While the dam has not been rated for condition assessment, its hazard potential is classified as high, emphasizing the need for regular maintenance and monitoring. With no state jurisdiction or regulatory agency overseeing its operations, the dam remains a local government-owned structure managed by the City of Lewistown.
Despite its critical role in mitigating flood risks, the City of Lewistown Dam lacks certain emergency preparedness measures, such as an Emergency Action Plan (EAP) and updated inundation maps. As climate change continues to impact water resources and increase the frequency of extreme weather events, it is essential for stakeholders to prioritize the safety and resilience of infrastructure like the City of Lewistown Dam to ensure the continued protection of communities and ecosystems in the area.

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.
