Summary

Built in 1932 and standing at a height of 46.8 feet, the dam has a storage capacity of 5,650 acre-feet and covers a surface area of 248 acres. The dam is regulated by the Texas Commission on Environmental Quality and undergoes regular inspections to ensure its structural integrity.

In 2008, Lake Placid Dam underwent structural modifications to maintain its functionality and safety. The dam features outlet gates for controlled water release and has a spillway width of 325 feet. Despite being classified as having a fair condition assessment, the dam's hazard potential is not available, indicating a need for continuous monitoring and maintenance. With its picturesque location and vital role in water resource management, Lake Placid Dam serves as a key infrastructure for both energy production and outdoor recreation along the Guadalupe River.

Enthusiasts of water resources and climate will find Lake Placid Dam to be a fascinating structure that melds engineering ingenuity with environmental stewardship. Its historical significance, combined with its operational efficiency in generating hydroelectric power, highlights the importance of sustainable water management practices. As climate change continues to impact water resources, dams like Lake Placid play a crucial role in mitigating risks and ensuring the resilience of our water infrastructure for future generations.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
