Summary
Completed in 1955, this earth dam stands at a height of 20 feet and spans 400 feet in length, providing fire protection, stock water, and a small fish pond for its primary purposes. With a storage capacity of 217 acre-feet, including a normal storage level of 88 acre-feet, this low-hazard dam serves the local community while also supporting the surrounding ecosystem.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Heckmiller #1 is regulated, permitted, and inspected by the state, ensuring its structural integrity and compliance with safety standards. Although the dam's condition has not been officially rated, its low hazard potential indicates a relatively low risk of failure or significant impact in the event of a breach. Despite lacking certain detailed information such as inspection dates and maintenance records, Heckmiller #1 remains a vital resource for water supply and ecosystem support in the region.
With its strategic location in the Custer County, Montana, Heckmiller #1 plays a crucial role in providing water resources for fire protection, livestock, and aquatic life. As climate change continues to impact water availability and quality, the management and maintenance of dams like Heckmiller #1 are essential for ensuring sustainable water use and ecosystem resilience in the face of changing environmental conditions. By staying informed about the status and condition of critical infrastructure such as Heckmiller #1, water resource and climate enthusiasts can contribute to the long-term sustainability of water systems in their communities.

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.
