Summary
This private earth dam, with a height of 13 feet and a length of 860 feet, serves as a crucial water resource with a storage capacity of 53 acre-feet, benefiting the local community and ecosystem. Despite its age, the dam remains in good condition, not rated for any hazards, showcasing its structural resilience and the ongoing commitment to its maintenance.
Operated solely for purposes beyond flood control or hydroelectric power generation, Tom Ranch Dam's association with the Natural Resources Conservation Service highlights its significance in managing water resources sustainably. While lacking a spillway, the dam's design reflects a balance between nature and human intervention, embodying the principle of harmonious coexistence with the environment. The risk assessment, labeling it as high risk, underscores the importance of continuous monitoring and management to uphold its functionality and safety standards.
With the Galveston District overseeing its jurisdiction, Tom Ranch Dam represents a collaborative effort between private ownership and public agencies to uphold water resource management. Its historical significance, combined with its vital role in the local water supply, positions the dam as a symbol of resilience and stewardship in the face of changing climate patterns and growing water demands. As enthusiasts of water resources and climate sustainability, Tom Ranch Dam serves as a beacon of proactive conservation practices and the importance of preserving water ecosystems 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.
