Summary

Completed in 1928, this earth dam stands at a height of 42 feet and stretches 1555 feet in length, harnessing the waters of the Guadalupe River for hydroelectric power generation and recreation purposes. With a maximum storage capacity of 6170 acre-feet and a surface area of 396 acres, the dam plays a crucial role in water resource management in the region.

Managed by the Texas Commission on Environmental Quality (TCEQ), Lake McQueeney Dam has a fair condition assessment as of April 2021. Equipped with two outlet gates for water control, the dam has a spillway width of 855 feet and a drainage area of 1697 square miles. While its hazard potential is not specified, the dam undergoes inspections every five years to ensure its structural integrity and safety standards are met. Despite its age, Lake McQueeney Dam continues to serve as a vital component in the local water infrastructure, offering both recreational opportunities and hydroelectric power generation.

As a significant feature in the Galveston District of Texas, Lake McQueeney Dam not only provides essential water storage but also contributes to the environmental and economic well-being of the area. With its historical significance and ongoing role in water management, this dam stands as a testament to the ingenuity and engineering prowess of its designers, serving as a crucial link between water resources and climate resilience in the region.

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.
