Summary
Built in 1950, this Earth dam stands at 20 feet tall and spans 200 feet in length, providing storage for fire protection, stock, and small fish pond purposes. With a capacity of 94 acre-feet, Corvette is regulated by the Montana Department of Natural Resources and Conservation, ensuring that it meets state permitting, inspection, and enforcement standards.
Despite its low hazard potential, Corvette's condition has not been officially rated, and there is no current Emergency Action Plan in place. However, the dam's location in Richland County, Montana, under the jurisdiction of the DNRC, signifies a commitment to maintaining its functionality and safety. As a vital resource for water management in the region, Corvette serves as a reminder of the importance of proper infrastructure maintenance and oversight in the face of changing climate conditions.
Water resource and climate enthusiasts can appreciate Corvette as an example of the intersection between human engineering and environmental stewardship. Its presence along TR-Hardscrabble Creek not only supports local water needs but also highlights the ongoing efforts to balance water management with ecological preservation. With its historic significance and regulatory oversight, Corvette stands as a testament to the importance of sustainable water resource management in the face of a changing climate landscape.

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.
