Summary
Built in 1959 by the USDA NRCS, this Earth-type dam stands at a structural height of 37 feet and serves primarily for irrigation purposes. With a maximum storage capacity of 21,887 acre-feet and a normal storage capacity of 7,735 acre-feet, Dmad plays a crucial role in water resource management in the region.
Managed by the Utah Division of Water Rights, Dmad is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. Despite being classified as having a high hazard potential, the dam is currently in fair condition as of the last assessment in 2007. The dam has a history of modifications, but specific details on these alterations are not available in the data.
Situated in a strategic location in Delta, Utah, Dmad not only provides vital irrigation water for agricultural activities but also contributes to flood control and water storage in the region. With its long history of service and ongoing state oversight, Dmad remains a key infrastructure for water management in Millard County.

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.
