Summary
Constructed in 1953 by the Natural Resources Conservation Service, this dam stands at 19 feet tall and spans 603 feet in length. With a storage capacity of 111 acre-feet, it serves the primary purpose of water resource management in the area.
Despite its low hazard potential, Hendricks Number 4 is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it meets all state inspection and enforcement standards. The dam has not been rated for its condition assessment, but it is regularly monitored to ensure its structural integrity and safety. With a maximum discharge capacity of 1890 cubic feet per second, this dam plays a crucial role in managing water flow and mitigating flood risks in the region.
For water resource and climate enthusiasts, Hendricks Number 4 serves as a noteworthy example of human intervention in water management. Its location along the TR-WHITE RIVER highlights its importance in regulating water levels and protecting downstream communities from potential flooding. While its current condition assessment is not rated, the dam's presence underscores the ongoing need for infrastructure maintenance and monitoring to ensure the resilience of water systems in the face of climate change challenges.

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.
