Summary

Completed in 1974, this earth dam stands at 25 feet in height and has a storage capacity of 71 acre-feet. Despite being state-regulated and inspected, its hazard potential is classified as low, with a condition assessment of "Not Rated." The dam's primary purpose is irrigation, serving as a vital water resource for agricultural activities in the area.

Situated in Congressional District 00, Montana, Conover #2 is overseen by the Department of Natural Resources and Conservation (DNRC) and falls under the jurisdiction of the state. Although the dam has not been assessed for its emergency action plan (EAP) readiness or risk management measures, it remains a key infrastructure for water management in the region. With its strategic location and role in supporting irrigation needs, Conover #2 plays a significant role in the local water resource and climate landscape.

As water resource and climate enthusiasts, understanding the key details of dams like Conover #2 is crucial for monitoring and managing water infrastructure effectively. By recognizing the dam's specifications, ownership, regulatory status, and purpose, enthusiasts can appreciate its importance in sustaining agricultural activities and water supply in the Yellowstone, Montana area. With ongoing state oversight and inspection, Conover #2 continues to contribute to the region's water security and resilience in the face of changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
