Summary
Completed in 1976, this earth dam stands at a height of 25 feet and has a storage capacity of 67 acre-feet. The dam is located on TR to Maries River and is managed by a private owner.
Despite its low hazard potential, Kleffner Lake Dam plays a crucial role in maintaining water supply for the area and supporting recreational activities. With a surface area of 5 acres and a drainage area of 120 square miles, the dam provides a habitat for various aquatic species. Additionally, the dam's condition assessment is currently not rated, emphasizing the need for regular inspections and maintenance to ensure its long-term stability and functionality.
Overall, Kleffner Lake Dam exemplifies the intersection of water resource management and climate resilience efforts in the region. Its strategic location, design, and purpose highlight the importance of sustainable infrastructure development to address the growing challenges of water scarcity and environmental conservation. Through coordinated efforts with local and state agencies, Kleffner Lake Dam continues to contribute to the community's water security and recreational opportunities while upholding safety standards for all stakeholders involved.

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.
