Summary
The dam, with a height of 16 feet and a length of 1975 feet, holds a normal storage capacity of 109 acre-feet and a maximum storage of 205 acre-feet. Situated on the TR-Nueces River, the dam is primarily used for recreation activities such as fishing, boating, and wildlife observation.
Despite not being state-regulated, Dobie Lake Dam is equipped with one outlet gate and is designed as an earth dam with a buttress core type. The dam's hazard potential is labeled as "Not Available," but its risk assessment is classified as high. With no spillway and a lack of inspection frequency data, the dam's condition assessment is marked as "Not Rated." Although the dam does not have an Emergency Action Plan prepared, it remains a significant feature in the local landscape for both water resource and climate enthusiasts to enjoy and explore.
Overall, Dobie Lake Dam stands as a historic structure in Texas that provides vital water supply and recreational opportunities for the surrounding community. As water resource and climate enthusiasts visit the dam, they can appreciate its engineering design and contribution to the local ecosystem. While the dam's risk assessment may raise concerns, its significance as a water management structure cannot be overlooked, making it a noteworthy destination for those interested in the intersection of water resources and climate dynamics.

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.
