Summary
Completed in 1938 for fire protection, stock, and small fish pond purposes, this earth dam stands at a height of 25 feet and has a length of 600 feet. With a storage capacity of 129 acre-feet, Gouchenour is regulated by the Montana Department of Natural Resources and Conservation (DNRC), ensuring proper permitting, inspection, and enforcement measures are in place.
Situated in a low hazard potential area, Gouchenour has not been rated for its condition assessment. Despite this, the dam continues to serve its primary purposes effectively. The dam's emergency action plan status, risk assessment, and management measures remain unreported, indicating a lack of recent updates in these crucial areas. As a key structure in the region, Gouchenour plays a vital role in providing essential water resources for fire protection and agricultural needs in the surrounding community.
Enthusiasts interested in water resource management and climate resilience will find Gouchenour's historical significance and current operational status intriguing. As a privately owned dam in Montana, Gouchenour's role in providing water storage for fire protection and stock purposes highlights the importance of maintaining and monitoring aging infrastructure to ensure continued safety and reliability. With its location in the picturesque city of Loma, Gouchenour stands as a testament to the intersection of human ingenuity and natural resources in managing water for multiple beneficial uses.

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.
