Summary
This structure, managed by the Natural Resources Conservation Service, serves the purpose of water resource management along the TRIB-BAD RIVER. With a maximum storage capacity of 25 acre-feet and a normal storage of 15 acre-feet, the dam plays a crucial role in regulating water flow and mitigating flood risks in the region.
Despite being classified as having a low hazard potential and not yet rated for condition assessment, Saville Number 1 is subject to state regulations and inspections by the South Dakota Department of Environment and Natural Resources. The dam is equipped with state-permitted outlets and emergency action plans, ensuring that any potential risks are managed efficiently. With Dusty Johnson (R) representing the area in Congress, the dam's safety and functionality are under constant scrutiny and oversight to protect both the local community and the environment.
As a key infrastructure in the St. Paul District managed by the US Army Corps of Engineers, Saville Number 1 stands as a testament to the importance of water resource management and climate resilience in the face of changing environmental conditions. The dam's strategic location and design enable it to effectively control water flow and contribute to the overall sustainability of the region. With its vital role in flood control and water storage, Saville Number 1 exemplifies the intersection of engineering excellence and environmental stewardship in safeguarding our water resources for future generations.

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.
