Summary
The dam, completed in 1950, serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 12 feet and a length of 120 feet, the dam has a storage capacity of 58 acre-feet and a normal storage capacity of 12 acre-feet. It is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and has a low hazard potential.
Despite its low hazard potential, the condition of Hastetter #2 has not been rated, and there is limited information available on its maintenance and emergency preparedness measures. The dam is not owned or funded by any federal agency and has not been modified in recent years. Located in a rural area of Richland County, the dam plays a crucial role in providing water resources for the surrounding community and supporting local wildlife. Water resource and climate enthusiasts will find Hastetter #2 to be a fascinating example of how small-scale dams can serve multiple purposes while also posing minimal risk to the environment and surrounding 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.
