Summary
Standing at a height of 25 feet and a length of 450 feet, the dam has a storage capacity of 500 acre-feet. The dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspection and enforcement to ensure its safety and compliance with state regulations.
With an uncontrolled spillway type and two uncontrolled and one valve outlet gates, Bermuda Dam poses a moderate risk level (3) according to the data available. The hazard potential and condition assessment of the dam are not currently rated, but it is noted that the emergency action plan (EAP) and inundation maps are not prepared or updated. The dam has not been modified in recent years, and its last inspection was conducted in March 2010.
Water resource and climate enthusiasts would likely be interested in the historical significance and engineering aspects of Bermuda Dam, as well as the ongoing regulatory oversight and risk management measures associated with its operation. The dam's location on the Nueces River and its role in supporting irrigation in the region make it a notable feature in the local water infrastructure landscape. Further monitoring and maintenance efforts may be necessary to ensure the continued safety and functionality of Bermuda Dam in the face of changing environmental conditions and potential hazards.

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.
