Summary
This private-owned Earth dam stands at a height of 14 feet and has a length of 1650 feet, with a storage capacity of 106 acre-feet. Despite being designed without a spillway, the dam is equipped with one outlet gate to manage water flow.
The dam is situated on the TR-Santa Isabel Creek and falls under the jurisdiction of the state of Texas, with state permitting and inspection requirements in place. While the dam's hazard potential is not available, it has been rated as high risk. Despite its age, the condition of Chupahueso Lake No 2 Dam has not been officially assessed, and emergency action plans and risk management measures have not been documented. With its critical role in supplying water to the region, it is crucial for stakeholders to prioritize the safety and maintenance of this essential infrastructure.
For water resource and climate enthusiasts, Chupahueso Lake No 2 Dam presents an intriguing case study of a privately-owned dam in Texas with a high-risk rating. The dam's historical significance, design features, and regulatory oversight offer valuable insights into the challenges and opportunities associated with managing water supply infrastructure in the face of evolving climate conditions. As discussions around water security and resilience continue to gain importance, understanding the complexities of dams like Chupahueso Lake No 2 Dam can provide valuable lessons for sustainable water resource management in the future.

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.
