Summary
Built in 1937, this earth dam stands at a height of 23 feet and has a length of 510 feet, providing a storage capacity of 390 acre-feet. The dam is regulated by the South Dakota Department of Agriculture and Natural Resources, with regular inspections and enforcement measures in place to ensure its safety and compliance with state regulations.
Despite its low hazard potential, Hendricks Number 2 plays a crucial role in managing water resources in the area, with a maximum discharge capacity of 630 cubic feet per second. The dam's primary purpose and specific functions are not explicitly stated, but its presence contributes to flood control, water storage, and possibly irrigation within the region. The dam has not been rated for its current condition, but with a history dating back over 80 years, it continues to be an important infrastructure for water management in the area.
Although limited information is available on the dam's emergency preparedness, risk assessment, and management measures, Hendricks Number 2 remains an integral part of the local water infrastructure. With its strategic location and capacity to store and regulate water flow, the dam serves as a vital resource for ensuring water security and resilience in the face of changing climate conditions. For water resource and climate enthusiasts, Hendricks Number 2 represents a significant structure that warrants further study and monitoring to enhance its effectiveness and safety for the future.

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.
