Summary
Built in 1971 by NDSWC, this earth dam stands at a height of 64.3 feet and has a structural height of 79 feet, serving primarily for recreational purposes. With a storage capacity of 1346 acre-feet and a surface area of 43.4 acres, the dam is situated on the Missouri-TR river and falls under the regulatory jurisdiction of NDSWC.
Despite being classified as having a significant hazard potential, Daub Dam is currently in a condition that has not been rated. The last inspection in April 2016 confirmed its moderate risk level, with no Emergency Action Plan (EAP) prepared or updated. The dam features an uncontrolled spillway with a width of 28 feet and is equipped with two valve outlet gates. With a drainage area of 6.2 square miles, the dam plays a crucial role in water resource management in the region and is subject to regular state inspections and enforcement.
As water resource and climate enthusiasts, the data surrounding Daub Dam presents an intriguing case study in dam engineering and management. With its significant hazard potential and moderate risk assessment, understanding and monitoring the condition of this earth structure is crucial for ensuring the safety of nearby residents and recreational users. The dam's role in providing water storage and recreational opportunities further underscores its importance in the local ecosystem and the need for continued regulatory oversight and maintenance.

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.
