Summary
Built in 1975, this earth-type dam boasts a height of 30 feet and a storage capacity of 144 acre-feet, with a normal storage level of 90 acre-feet. The dam, situated on Wolf Creek, serves as a vital resource for the surrounding area.
Despite its small surface area of 9 acres, the Lona Lou Lake Dam plays a crucial role in ensuring the safety and well-being of the community, with a high hazard potential due to its purpose and design. While its condition is currently not rated, the dam remains a key feature for local fire protection and recreational activities. With a lack of state regulation and enforcement, the maintenance and upkeep of this essential structure fall solely on its private owner.
For water resource and climate enthusiasts, the Lona Lou Lake Dam represents a fascinating case study in private dam ownership and management. Its significant storage capacity and dual-purpose design make it a valuable asset for both emergency preparedness and leisure activities. As efforts to assess and mitigate potential risks continue, the dam stands as a testament to the importance of sustainable water resource management in the face of changing climates and growing populations.

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.
