Summary
Completed in 1940, this dam stands at a height of 30 feet and has a storage capacity of 79 acre-feet, with a normal storage level of 51 acre-feet. The structure is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected, permitted, and enforced by state agencies to ensure its safety and compliance with regulations.
Despite its low hazard potential and current "Not Rated" condition assessment, Loubren INCorporated #1 plays a crucial role in providing water supply to the surrounding area. The dam is situated on diffused surface water, with a drainage area and spillway type not specified in the data. The structure has not been modified in recent years, and there is no available information on emergency action plans, risk assessments, or inundation maps prepared for the dam.
Overall, Loubren INCorporated #1 serves as a vital water resource infrastructure in Toole County, Montana, contributing to the water supply needs of the region. With its state-regulated status and regular inspection protocols, the dam remains a key component of the water management system in the area. However, further details on the dam's condition assessment, emergency preparedness, and risk management measures would provide a more comprehensive understanding of its operation and safety standards.

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.
