Summary

Completed in 1973, this earth-type dam stands at a height of 50 feet and spans a length of 2290 feet along Mullin Creek. Its primary purpose is flood risk reduction, with a storage capacity of 4457 acre-feet and a normal storage of 200 acre-feet.

The dam's spillway, with a width of 303 feet, is uncontrolled, and it has outlet gates consisting of a slide (sluice gate) and two uncontrolled gates. Although its condition assessment is rated as fair, the dam is regularly inspected by the Texas Commission on Environmental Quality (TCEQ), with the last inspection conducted in April 2021. The risk assessment for this dam is moderate, and it is situated in a drainage area of 12.05 square miles, serving as a vital asset in managing water resources in the region.

Water resource and climate enthusiasts will find the Brown Mullin WS SCS Site 2 Dam a fascinating structure that plays a crucial role in flood risk reduction along Mullin Creek. With its impressive design and strategic location, the dam contributes to the overall water management system in Mills County, Texas. As a state-regulated and inspected dam, it ensures the safety and security of the surrounding areas while also serving as a valuable resource for water conservation efforts 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.
