Summary

Completed in 1968, this earth dam stands at a height of 37 feet and has a length of 500 feet, with a storage capacity of 118 acre-feet. The dam is situated on La Barque Creek and is regulated by the Dam and Reservoir Safety Program in Missouri.

With a hazard potential rated as high and a moderate risk assessment score of 3, Rustic Hills Lake Dam has been deemed to be in satisfactory condition as of the last assessment in 2007. Regular inspections are conducted every three years, with the most recent one taking place in August 2015. Despite its age, the dam has proven to be structurally sound and capable of managing a maximum discharge of 551 cubic feet per second.

For water resource and climate enthusiasts, Rustic Hills Lake Dam offers a fascinating example of a privately owned recreational structure that plays a crucial role in water management in the region. Its history of safe operation and regular maintenance serve as a testament to the importance of efficient dam regulation and inspection practices in ensuring the safety of communities and the sustainability of water resources.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
