Summary

Constructed in 1954 by USDA NRCS, this earth dam with a height of 44 feet and a length of 3050 feet serves to protect the surrounding area from potential flooding events. With a normal storage capacity of 433 acre-feet and a drainage area of 19.8 square miles, the dam plays a vital role in managing water resources in the region.

Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), East Laterals Trinity WS SCS Site 2 Dam has undergone structural modifications in 1984 to enhance its functionality. The spillway, with a width of 400 feet, provides an uncontrolled release of excess water during high-flow events. Despite being rated as "Not Available" in terms of hazard potential, the dam's risk assessment indicates a moderate level of risk (3), prompting the need for continued monitoring and management to ensure its effectiveness in safeguarding the community.

As water resource and climate enthusiasts, understanding the significance of East Laterals Trinity WS SCS Site 2 Dam in flood risk reduction and water management is crucial. With its historical importance and ongoing role in protecting the area from potential flooding, this earth dam serves as a testament to the importance of resilient infrastructure in mitigating the impacts of extreme weather events. By staying informed about its design, capacity, and risk assessment, we can appreciate the complexities of water resource management and the critical role that structures like this dam play in safeguarding communities and ecosystems.

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.
