Summary

Standing at a height of 30 feet, the earth dam has a storage capacity of 86 acre-feet, with a normal storage level of 50 acre-feet. Despite being classified as having a significant hazard potential, the dam's condition assessment is currently not rated, indicating a need for further evaluation.

Managed by the Montana Department of Natural Resources and Conservation (DNRC), the Robin Hood #2 dam is subject to state regulation, inspection, and enforcement. With its primary purpose being irrigation, the dam plays a crucial role in water resource management in Meagher County. While the dam's emergency action plan status and risk assessment are currently unknown, its presence highlights the importance of maintaining and monitoring infrastructure for water supply and climate resilience.

As a vital component of the local water infrastructure, the Robin Hood #2 dam serves as a key resource for agricultural activities in the region. With the potential to impact downstream areas in the event of a failure, the dam's maintenance and risk management measures are essential for ensuring the safety and sustainability of water resources in the area. Enthusiasts of water resource management and climate adaptation will find the Robin Hood #2 dam to be a compelling case study in balancing the needs of irrigation with the imperative of dam safety.

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.
