Summary
With a height of 29 feet and a length of 431 feet, the dam holds a maximum storage capacity of 42 acre-feet and serves to stabilize the grade of the surrounding area. Situated on the Salt River in Adair County, the dam covers an area of 2 acres and has a drainage area of 76.8 square miles.
Despite being classified as having a low hazard potential, Reynolds Dam is subject to moderate risk assessment with a score of 3. While the dam itself is not rated for condition, its emergency action plan status, inundation maps, and risk management measures are not available. The uncontrolled spillway, with a width of 12 feet, can handle a maximum discharge of 24 cubic feet per second. The dam has not been inspected recently, and it is not regulated or permitted by the state, indicating a lack of oversight in terms of safety and maintenance.
For water resource and climate enthusiasts, Reynolds Dam presents an interesting case study of a privately owned structure with potential ecological benefits as a fish and wildlife habitat. However, the lack of regulatory oversight and maintenance raises concerns about the potential risks associated with the dam. With its location in a moderate-risk area and limited information on emergency preparedness, further evaluation and monitoring of Reynolds Dam are essential to ensure the safety of the surrounding community and the integrity of the structure.

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.
