Summary

Owned by the local government and designed by USDA NRCS, this structure plays a crucial role in flood risk reduction along the Long Branch stream. Completed in 1955, this earth dam stands at a height of 29 feet and has a storage capacity of 354 acre-feet, serving a drainage area of 1.35 square miles.

Managed by the TCEQ and regulated by the state of Texas, Upper East Fk Laterals WS SCS 6a has not only withstood the test of time but has also undergone modifications in 2008 to ensure its continued effectiveness. With a risk assessment rating of "High (2)", this structure's condition is currently not rated, highlighting the need for further evaluation and potential risk management measures. Despite its critical role in flood control, the dam lacks a spillway and has a single slide gate for water discharge, emphasizing the importance of regular inspections and maintenance to mitigate any potential hazards.

As water resource and climate enthusiasts, it is essential to recognize the significance of Upper East Fk Laterals WS SCS 6a in safeguarding the local community from flooding events. With its historical background, structural details, and regulatory oversight, this infrastructure serves as a key component in water management efforts in Rockwall, Texas. As we strive to protect and preserve our water resources, ongoing monitoring and maintenance of structures like Lofland Lake are crucial to ensure their continued functionality and resilience in the face of changing climate conditions.

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.
