Summary

Completed in 1979, this earthen dam stands at a height of 20 feet with a length of 1000 feet, providing a storage capacity of 1112 acre-feet. It serves as a crucial water resource for the area, with a normal storage capacity of 141 acre-feet and a surface area of 22 acres.

Managed by the Texas Commission on Environmental Quality (TCEQ), Brockstein Lake Dam is regulated, permitted, inspected, and enforced by state agencies. The dam has no spillway and a hazard potential that is not available, but its risk assessment is rated as high. The dam's condition is not rated, and it lacks emergency action plans and inundation maps. Despite these challenges, Brockstein Lake Dam remains a vital structure for water resource management in the region, supporting various purposes and serving as an important asset for the community.

The dam's location on TR-ALUM CREEK under the Galveston District of the US Army Corps of Engineers highlights its significance in the region's water infrastructure. While there are no associated structures and limited data on its maintenance and inspection history, Brockstein Lake Dam stands as a testament to the importance of sustainable water management practices in the face of climate change and increasing water demands. Enthusiasts of water resources and climate resilience will find Brockstein Lake Dam to be a fascinating case study in the intersection of water infrastructure, environmental stewardship, and community resilience.

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.
