Summary
The dam stands at a height of 48.8 feet with a hydraulic height of 46.1 feet, containing a maximum storage capacity of 608 acre-feet and a normal storage capacity of 517 acre-feet. The reservoir created by the dam covers an area of 56 acres and has a drainage area of 2.2 square miles, with the Bull Bayou-TR river or stream flowing through it.
Managed by the local government, Sanderson Dam is regulated by the Arkansas Natural Resources Commission (ANRC) and undergoes regular state inspection, permitting, and enforcement processes. With a significant hazard potential and condition assessment not rated, the dam's emergency action plan (EAP) status and risk management measures are currently not specified. The dam, classified as a gravity type, has not been modified over the years and does not have any associated locks or spillways.
Enthusiasts of water resources and climate conservation will find Sanderson Dam an intriguing structure due to its historical significance, vital role in water supply, and the potential environmental impact it holds. As one of the key water management systems in Montgomery County, Arkansas, the dam's operation and maintenance are essential for ensuring continued water supply reliability and mitigating any potential risks associated with its significant hazard potential. The ongoing monitoring and assessment of Sanderson Dam underscore the importance of sustainable water resource management practices in the face of changing climate conditions.

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.
