Summary

Standing at a height of 25 feet with a length of 1100 feet, this earth dam serves a primary purpose of "Other" and has a storage capacity of 592 acre-feet. The dam features an uncontrolled spillway with a width of 48 feet and is equipped with two uncontrolled outlet gates.

Despite being labeled as having a "Fair" condition assessment, Brown Dam poses a moderate risk with a Hazard Potential rating of "Not Available." It is subject to inspections every five years, with the last assessment conducted in December 2015. While the dam does not have an Emergency Action Plan (EAP) in place, it meets regulatory guidelines and has not experienced any major modifications since its construction.

Water resource and climate enthusiasts interested in Brown Dam can appreciate its unique design and operational features, as well as its strategic location within the Fort Worth District. With a focus on safety and risk management, ongoing inspections and maintenance efforts ensure that the dam continues to serve its purpose effectively while mitigating potential hazards.

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.
