Summary
This private-owned earth dam stands at a height of 20 feet, with a length of 1720 feet, and has a storage capacity of 250 acre-feet. The dam primarily functions for water supply purposes and is situated on the TR-Little Leopard Creek Oakvi river or stream.
Despite its vital role in water resource management, Brown Lake Dam is not regulated by the state and has not been rated in terms of its condition. The dam lacks a spillway and has only one outlet gate, indicating potential limitations in its flood control capabilities. However, with a risk assessment rating of "High (2)", there may be a need for increased monitoring and maintenance to ensure the safety and stability of the structure.
For water resource and climate enthusiasts, Brown Lake Dam presents an intriguing case study of a privately-owned earth dam in Texas. With its historical significance and importance in water supply management, the dam's design and operational details raise questions about its resilience to potential hazards and the need for enhanced risk management measures. As discussions around water infrastructure and climate adaptation continue to grow, Brown Lake Dam stands as a reminder of the complex challenges faced in ensuring the sustainability of water resources in the face of changing environmental conditions.

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.
