Summary
Built in 1964 by the Natural Resources Conservation Service, this dam stands at 27 feet tall and stretches 318 feet in length. With a storage capacity of 23 acre-feet and a maximum discharge of 630 cubic feet per second, Brost Number 10 serves as a vital structure for water resource management in the area.
Despite being classified as a low hazard potential structure and not currently rated for condition assessment, Brost Number 10 is regulated, permitted, inspected, and enforced by the South Dakota Department of Environment and Natural Resources. With state jurisdiction, this dam plays a crucial role in flood control, irrigation, and water supply for the surrounding community. The dam's emergency action plan status, risk assessment, and management measures are currently not available, indicating the need for further evaluation and preparedness in case of potential emergencies.
In the realm of water resource and climate enthusiasts, Brost Number 10 serves as a significant point of interest due to its strategic location and importance in water management. The dam's history, design, and operational aspects make it a key structure in maintaining water security and mitigating potential risks in the region. As efforts continue to monitor and assess its condition, Brost Number 10 remains a focal point for ensuring the sustainability and resilience of water resources in Jones, South Dakota.

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.
