Summary
Built in 1954 for fire protection, stock, and small fish pond purposes, Heble stands at a height of 19 feet with a hydraulic height of 15 feet. With a storage capacity of 101 acre-feet, this earth dam spans 600 feet in length and serves as a vital resource in the region. The dam is under the regulatory oversight of the Montana Department of Natural Resources and Conservation (DNRC), ensuring that it meets state permitting, inspection, and enforcement standards.
Despite its low hazard potential, Heble has not been rated for its condition assessment. The dam's emergency action plan (EAP) status, including preparation and revision dates, remains unclear. While no risk assessment or management measures have been documented, the dam's risk characteristics and potential impacts are unknown. Given its location in Fergus County and its proximity to the Omaha District of the US Army Corps of Engineers, Heble plays a crucial role in water resource management and climate resiliency efforts in the area. Enthusiasts of water resources and climate change will find Heble to be a key infrastructure asset worth monitoring and studying for its importance in the local ecosystem.

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.
