Summary
The dam is privately owned and operates under the jurisdiction of the state of Missouri. With a height of 25 feet and a storage capacity of 67 acre-feet, the dam helps regulate water flow and provides recreational opportunities in the area.
Despite its low hazard potential, Reynolds Lake Dam has not been rated for its condition assessment. The dam, primarily constructed from earth materials with a buttress core, has not undergone recent inspection or maintenance. While the dam has not been associated with any federal agencies for funding or oversight, it remains an important structure for water resource management and wildlife habitat in the region.
Water resource and climate enthusiasts interested in Reynolds Lake Dam can appreciate its role in providing essential services such as fire protection and maintaining a healthy ecosystem. The dam's location on Blackjack Creek in Johnson County, Missouri, highlights the importance of sustainable water management practices for both human and environmental well-being. As efforts to address climate change intensify, understanding and maintaining infrastructure like Reynolds Lake Dam will be crucial in ensuring water security and resilience 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.
