Summary

This Earth dam stands at a height of 11 feet and has a storage capacity of 70 acre-feet. The primary purpose of Albro is to support irrigation in the area, with a low hazard potential and no available condition assessment. Situated on the Tr- Willow Creek S river or stream, this dam plays a crucial role in managing water resources in the region.

Managed by the Natural Resources Conservation Service, Albro serves as a vital infrastructure for water conservation and agricultural activities in Madison County. With a maximum discharge capacity of 97 cubic feet per second, this dam ensures a reliable water supply for the surrounding area. Despite its low hazard potential, the condition assessment for Albro is currently not available, highlighting the need for regular monitoring and maintenance to uphold its functionality.

As a key component of the water management system in the region, Albro plays a significant role in ensuring water security for agricultural purposes. With its strategic location and design, this Earth dam stands as a testament to the importance of sustainable water resource management in Montana. The collaboration between federal agencies and private owners underscores the shared commitment to preserving and utilizing water resources effectively 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.
