Summary
Built in 1965 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock watering, and small fish pond habitat. With a height of 15 feet and a storage capacity of 55 acre-feet, Elias #1 plays a crucial role in water resource management in the area.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Elias #1 is regulated, inspected, and enforced to ensure its safety and functionality. Despite being classified as low hazard potential and not yet rated for condition assessment, this dam represents a key infrastructure for water supply and environmental conservation in the region. The dam's location in Blaine County, Montana, makes it an essential component in the local water distribution network.
With a maximum discharge of 90 cubic feet per second and a spillway width of 20 feet, Elias #1 is designed to withstand potential floods and emergencies. Although the dam has not been fully assessed for risk management measures, its presence along the N Chinook Irrigation Canal highlights its importance in agricultural irrigation and fire protection efforts. As a focal point for water resource enthusiasts, Elias #1 stands as a testament to sustainable water management practices in Montana.

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.
