Summary

Built in 1969 by the USDA NRCS, this earth dam boasts a height of 27 feet and a length of 1880 feet, providing a storage capacity of 530 acre-feet. With a primary purpose of flood risk reduction, the dam also serves irrigation needs in the region.

Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Se Laterals WS SCS Site 3 Dam has been inspected regularly, with its condition assessed as fair. Despite a high risk classification of 2, the dam's emergency action plan is up to date, ensuring preparedness for any unforeseen events. With a flap outlet gate and no spillway, the dam symbolizes a harmonious blend of engineering and environmental stewardship.

For water resource and climate enthusiasts, the Se Laterals WS SCS Site 3 Dam presents a fascinating case study in sustainable water management. Its strategic location on TR-Antelope Creek and its effective flood risk reduction measures make it an essential component of the local water infrastructure. With its historical significance and ongoing regulatory oversight, this dam serves as a model for balancing water resource development with environmental protection in the heart of Texas.

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.
