Summary
The dam, constructed with earth and buttress core types, stands at a height of 25 feet and has a storage capacity of 21 acre-feet. Despite being non-federally regulated, the dam has state permitting and inspection in place to ensure its safety and functionality.
With a hazard potential deemed "Not Available" and a condition assessment of "Not Rated," Hall Dam poses a moderate risk, categorized as high (2). The last inspection date recorded was in 1972, indicating a need for updated assessments and maintenance. Although the dam lacks certain emergency preparedness measures, such as an Emergency Action Plan (EAP), it serves as a crucial water resource for the surrounding area.
In the realm of water resource and climate enthusiasts, Hall Dam provides an intriguing case study for private irrigation infrastructure in Texas. Its historical significance and risk assessment present opportunities for further research and potential improvements to ensure the dam's longevity and effectiveness in water management for agricultural purposes.

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.
