Summary
While primarily constructed for recreational purposes, this earth dam plays a crucial role in providing water storage and flood control in the region. Despite being privately owned, the dam is not regulated by the state, posing a high hazard potential due to its lack of recent inspections and condition assessments.
Located in Boone County, Missouri, the Lake Cyrene Dam offers a surface area of 7 acres and a normal storage capacity of 50 acre-feet. However, with a high hazard potential and no recent inspections since 1981, concerns arise regarding its structural integrity and emergency preparedness. Although the dam is not federally owned or funded, its significance in water resource management and climate resilience cannot be overlooked.
As water resource and climate enthusiasts, attention must be drawn to the Lake Cyrene Dam's condition assessment, emergency action plan, and risk management measures to ensure the safety of the surrounding community and the sustainability of the dam's functionality. Collaborative efforts between private owners, state agencies, and stakeholders are crucial in safeguarding this important water resource infrastructure 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.
