Summary
This water treatment pond plays a crucial role in tailings management, primarily serving as a containment structure for waste materials. Completed in 2009, this earth dam with a stone core stands at a height of 41.5 feet and has a storage capacity of 376 acre-feet.
Managed by the Idaho Department of Water Resources, Delamar Wmp-1 is subject to state regulations, inspections, and enforcement to ensure its safe operation. Despite being classified as having a low hazard potential, the structure received a moderate risk assessment rating of 3, indicating the need for ongoing monitoring and management. The dam's condition was last assessed as satisfactory in April 2016, with regular inspections scheduled every five years to ensure its continued safety and reliability.
Located in a remote area and situated near the Henrietta Drainage and Jordan Creek, Delamar Wmp-1 serves as a critical component of water resource management in the region. With its uncontrolled spillway and valve outlet gates, this structure plays a vital role in safeguarding the surrounding environment and communities from potential water-related risks. As water resource and climate enthusiasts, understanding and monitoring the operation of structures like Delamar Wmp-1 is essential for ensuring the sustainable management of water resources in the face of changing environmental conditions.

Dam Data Reference
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.
