Summary
Constructed in 1961 by the Natural Resources Conservation Service, this dam stands at a height of 28 feet and has a storage capacity of 154 acre-feet. The primary purposes of Tribe No.4 include water supply, fire protection, stock maintenance, and small fish pond management, making it a multi-functional infrastructure for the community.
With a low hazard potential and a current condition assessment of "Not Rated," Tribe No.4 remains a stable and reliable structure for water resource management in Ziebach County, South Dakota. While lacking certain regulatory oversight and inspection requirements at the state level, this dam continues to fulfill its primary purpose of providing essential water resources to the surrounding area. As climate change impacts water resources, the presence of structures like Tribe No.4 becomes increasingly important for ensuring sustainable water supply and management in the region.
As water resource and climate enthusiasts, understanding the significance of Tribe No.4 in the local ecosystem is crucial for promoting sustainable water management practices. With its strategic location on the TR MOREAU river and its multiple benefits for the community, this earth dam exemplifies the intersection of human infrastructure and natural resource conservation. By recognizing the importance of structures like Tribe No.4 and advocating for their maintenance and improvement, we can contribute to the resilience of water resources in the face of changing climate conditions.

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.
