Tranquitas Lake Dam Reservoir Report
Nearby: Dairy Barn Lake Dam Tulosa Lake Dam
Last Updated: April 1, 2026
Tranquitas Lake Dam, located in Kingsville, Texas, was completed in 1938 and serves as a crucial resource for fish and wildlife preservation in the area.
Summary
The dam, primarily designed by Harkins Engineering and Peurifoy & Patterson, stands at a height of 15.3 feet and has a hydraulic height of 12 feet, with a storage capacity of 25,406 acre-feet. The dam's main purpose is to support fish and wildlife habitats, as well as provide fire protection and stock small fish ponds.
Despite its age, Tranquitas Lake Dam has undergone structural modifications in 2012 to ensure its continued functionality and safety. The dam features an uncontrolled spillway with a width of 951 feet and several outlet gates for water management. The risk assessment for the dam is moderate, with a hazard potential rating of not available. The dam is regulated and inspected by the Texas Commission on Environmental Quality (TCEQ), ensuring compliance with state regulations and frequent evaluations to maintain its integrity.
With its significant role in supporting local ecosystems and providing important water resources, Tranquitas Lake Dam stands as a vital structure in Kleberg County. Its strategic location along Tranquitas Creek and commitment to wildlife preservation make it a key asset in the region's water management infrastructure, highlighting the importance of sustainable practices in safeguarding our natural resources for future generations.

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.
