Summary

Built in 1956 by the USDA NRCS, this earth dam stands at a height of 29 feet and serves the primary purpose of flood risk reduction. With a normal storage capacity of 85 acre-feet and a drainage area of 1.18 square miles, this dam plays a crucial role in protecting the surrounding area from potential flooding events.

Located along the TR-LONG BRANCH river/stream, the Upper East Fk Laterals WS SCS Site 8 Dam has not been rated for condition assessment but is classified as having a high risk potential. Despite not having a spillway, this dam features a slide (sluice gate) outlet gate to regulate water flow. The dam's structural height of 29 feet and length of 1424 feet make it a significant water resource management asset in the region. With state regulation and inspection by the Texas Commission on Environmental Quality (TCEQ), this dam ensures the safety and security of the local community in case of emergency situations.

In summary, the Upper East Fk Laterals WS SCS Site 8 Dam is a critical infrastructure for flood risk reduction in Rockwall, Texas. Managed by the local government and designed by the USDA NRCS, this earth dam provides essential water storage and protection for the surrounding area. With state oversight and a high-risk potential classification, this dam underscores the importance of sustainable water resource management and climate resilience 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.
