Summary
Built in 1954, this earth dam stands at a height of 28 feet and has a storage capacity of 147 acre-feet. With a drainage area of 7.4 square miles and a surface area of 22 acres, Spaulding plays a crucial role in regulating the flow of the Tr Madelin Plains river.
Managed by the Natural Resources Conservation Service, Spaulding is state-regulated and undergoes regular inspections to ensure its satisfactory condition and low hazard potential. While the dam has not undergone significant modifications over the years, it remains a vital component of the water supply infrastructure in the region. As a key player in water resource management, Spaulding contributes to the sustainable use of water for irrigation and other purposes in the area.
With its strategic location and efficient design, Spaulding exemplifies the importance of responsible dam management in ensuring water security and climate resilience. As water resource and climate enthusiasts, understanding the significance of structures like Spaulding is crucial for promoting sustainable water management practices and safeguarding our natural resources for future generations.

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.
