Summary
Situated on TR-SAND CREEK in the city of VAN NORMAN, this dam has a height of 20 feet and a length of 150 feet, with a storage capacity of 58 acre-feet. While not rated for condition assessment, the dam is deemed to have low hazard potential.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Montana #28 is inspected, permitted, and enforced by the state agency. With a primary purpose of serving fire protection and agricultural needs, the dam also contributes to small-scale fishing activities in the area. Despite its relatively low hazard potential, the dam's emergency action plan status and risk assessment measures are currently not evaluated, suggesting a potential area for improvement in future management strategies.
In the broader context of water resource and climate management, understanding the key features and regulatory oversight of structures like Montana #28 is crucial for ensuring the safety and sustainability of water infrastructure. As climate change continues to impact water availability and quality, the effective monitoring and maintenance of dams like Montana #28 play a critical role in safeguarding both local communities and ecosystems in the region.

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.
