Summary
Constructed in 1977, this dam stands at 30 feet tall with a length of 330 feet and a storage capacity of 100 acre-feet. Despite its low hazard potential, it is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it meets all state permitting, inspection, and enforcement requirements.
With a moderate risk assessment rating of 3, Bonot Ratedk No.1 is considered to have some level of risk associated with its operations. While it has not been condition-rated, it is equipped with an uncontrolled spillway and lacks outlet gates. The dam's emergency action plan status is unclear, raising questions about its readiness for potential incidents. Overall, the dam's risk management measures and hazard mitigation strategies remain unspecified.
Owned by a private entity, Bonot Ratedk No.1 serves as a vital water resource in the region, highlighting the intersection of water management, climate resilience, and infrastructure safety. As water resource and climate enthusiasts, it is crucial to monitor the condition and regulatory compliance of such structures to ensure the sustainable and secure management of our water resources for future generations.

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.
