Summary

Owned by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), this earth dam with a height of 54 feet and a length of 2214 feet serves the primary purpose of flood risk reduction along the East Prong Whites Creek. With a storage capacity of 3237 acre-feet and a maximum discharge of 6355 cubic feet per second, the dam plays a crucial role in managing water flow and safeguarding the surrounding areas from potential flooding.

Managed by the Natural Resources Conservation Service, the East Fork Above Lavon WS SCS Site 39 Dam has been assessed to be in fair condition as of April 2021, with a moderate risk level assigned. The dam features an uncontrolled spillway and outlet gates, demonstrating a commitment to effective water management practices. Despite its relatively small surface area of 34 acres, the dam covers a drainage area of 6.25 square miles, showcasing its importance in maintaining hydrological balance in the region. With regular inspections and a designated emergency action plan, the dam ensures that it meets the necessary safety guidelines and remains prepared for any potential risks.

Overall, the East Fork Above Lavon WS SCS Site 39 Dam stands as a vital infrastructure component in the region, serving as a reliable flood risk reduction measure with a focus on water resource management and climate resilience. As climate change continues to impact water systems, dams like this play a crucial role in mitigating risks and ensuring the safety and well-being of local communities. The collaborative efforts of various agencies and stakeholders involved in the operation and maintenance of the dam underscore the importance of proactive measures in safeguarding water resources for future generations.

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.
