Summary
This state-regulated dam, managed by the Department of Natural Resources and Conservation (DNRC), serves multiple purposes including fire protection, stock, and small fish pond maintenance. Built in 1938, the earth dam stands at a height of 25 feet with a storage capacity of 71 acre-feet, providing essential water management for the surrounding area.
Despite being classified as low hazard potential, State #3's dam has not been rated for its condition assessment. The dam, with a length of 80 feet, is regularly inspected, permitted, and enforced by state authorities, ensuring its structural integrity and safety for the community. Situated in Congressional District 00, Montana, State #3 is crucial for water resource and climate enthusiasts interested in sustainable water management practices and the impact of dams on local ecosystems.
Located in Loma, Montana, State #3 is a focal point for water enthusiasts due to its role in maintaining water resources for fire protection, agriculture, and wildlife conservation. With a design capacity of 71 acre-feet and a hydraulic height of 25 feet, this earth dam provides essential water storage for the region. Managed by the DNRC, the dam undergoes regular inspections and enforcement to ensure its operational efficiency and safety for the community. For those interested in the intersection of water resource management and climate resilience, State #3 in Liberty, Montana, offers a fascinating case study in sustainable dam infrastructure and ecosystem conservation.

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.
