Summary
The dam, constructed in 1983, is an Earth-type structure with a height of 21 feet and a length of 500 feet. It has a storage capacity of 400 acre-feet and a drainage area of 9 square miles. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is subject to state permitting, inspection, and enforcement.
The dam has a significant hazard potential and its condition is currently not rated. Emergency action plans and risk assessment measures are not available for this structure. The dam poses a risk to the surrounding area in case of failure, and it is important for Person #1 to ensure proper maintenance and compliance with regulatory requirements to reduce the risk of potential emergencies. With a maximum discharge capacity of 2100 cubic feet per second, this dam plays a crucial role in water resource management in the region.
As a water resource enthusiast, Person #1 should be actively involved in monitoring the condition of the dam, conducting regular inspections, and implementing necessary risk management measures to protect both the dam structure and the downstream communities. By staying informed about the regulatory requirements and best practices for dam safety, Person #1 can contribute to the sustainable management of water resources and help mitigate the potential impacts of climate change on the region's water infrastructure.

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.
