Se Laterals Ws Scs Site 1 Dam Reservoir Report

Last Updated: December 5, 2025

Located in San Saba, Texas, the Se Laterals WS SCS Site 1 Dam stands as a crucial piece of infrastructure designed by the USDA NRCS to mitigate flood risk along Antelope Creek.

Summary

Completed in 1969, this earth dam reaches a height of 33 feet and spans a length of 3,235 feet, providing a storage capacity of 1,710 acre-feet. Despite its primary purpose of flood risk reduction, the dam currently lacks a spillway, presenting a potential hazard to the surrounding area.

Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Se Laterals WS SCS Site 1 Dam is subject to state jurisdiction, permitting, inspection, and enforcement. While the dam's condition remains unrated, it is considered to have a high risk level. With no designated emergency action plan or inundation maps prepared, it is crucial for stakeholders and authorities to prioritize risk management measures and ensure the safety of downstream communities in the event of a dam failure. The presence of only one outlet gate further underscores the importance of regular maintenance and monitoring of this vital water resource infrastructure.

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.
