Summary
This private dam, standing at a height of 20 feet and with a length of 1200 feet, primarily stores water for agricultural purposes. Situated on Hackberry Creek, the dam is classified as an earth dam with a buttress core type.
Despite its importance for irrigation, Tom Neff Lake Dam lacks certain safety features such as a spillway, which raises concerns about its hazard potential. The dam's risk assessment is rated as high, indicating a need for increased monitoring and maintenance to ensure its structural integrity. While the dam is state regulated with permitting and inspection requirements in place, there is no enforcement agency designated for overseeing its operations.
As an essential water resource infrastructure in the area, Tom Neff Lake Dam plays a crucial role in supporting local agriculture. However, with its risk assessment indicating potential hazards and the lack of certain safety features, there is a need for proactive measures to mitigate risks and ensure the dam's long-term stability. Enthusiasts of water resources and climate may find interest in monitoring the condition and management of this dam to safeguard its functionality and prevent any potential disasters.

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.
