Summary

Constructed in 1965, this Earth-type dam serves multiple purposes including fire protection, stock watering, and small fish pond maintenance. With a height of 30 feet and a length of 500 feet, the dam has a storage capacity of 214 acre-feet, providing essential water resources for the local area.

Managed by the Montana Department of Natural Resources and Conservation (DNRC), Qalqiliya is regulated, permitted, inspected, and enforced by the state agency to ensure its safe operation. Despite its low hazard potential and current "Not Rated" condition assessment, the dam plays a crucial role in water management and conservation efforts in Blaine County, Montana. As an integral part of the local infrastructure, Qalqiliya stands as a testament to sustainable water resource management practices.

While lacking certain detailed information such as spillway types and inspections, Qalqiliya continues to support the community in times of need, highlighting its importance in water storage and distribution. As climate change impacts water resources globally, the presence of well-maintained dams like Qalqiliya becomes increasingly vital for ensuring water security and resilience in the face of changing environmental conditions. From fire protection to stock watering, this dam remains a critical asset for both human and ecological needs in the region.

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.
