Summary
This private-owned Earth dam stands at a height of 10 feet and has a length of 979 feet, with a storage capacity of 136 acre-feet. The dam is situated on TR-Cibolo Creek, within the Galveston District, and primarily serves the purpose of water supply.
Despite its essential role in providing water, Martindale Tank Dam is not currently regulated by the state and has not been rated for its condition. The dam does not have a spillway and features one outlet gate. It is interesting to note that the dam is considered to have a high risk potential, indicating the need for thorough risk assessment and management measures to ensure its stability and safety. The surrounding area covers 15 acres, making it a relatively small but crucial water resource in the region.
For water resource and climate enthusiasts, Martindale Tank Dam presents an intriguing case study in managing and maintaining essential infrastructure for water supply. With its unique design features and location on TR-Cibolo Creek, this Earth dam highlights the importance of ongoing inspections and proper risk assessment to safeguard against potential hazards. As a private-owned structure with limited state oversight, the dam's condition and risk potential warrant further attention to ensure its continued functionality and safety for the surrounding community.

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.
