Summary

Constructed in 1952 by the USDA NRCS, this earth dam stands at a height of 40 feet and stretches 1830 feet in length, with a storage capacity of 533 acre-feet. The dam's primary purpose is flood risk reduction, but it also supports fire protection, stock, small fish pond, and recreational activities.

Managed and regulated by the Texas Commission on Environmental Quality (TCEQ), the dam is inspected every five years to ensure its structural integrity. With a fair condition assessment as of November 2015, the dam presents a moderate risk level (3) and has an uncontrolled spillway with a width of 85 feet. Despite its non-USACE status, the East Fork Above Lavon WS SCS Site 13 Dam plays a vital role in water resource management and climate resilience efforts in Collin County.

Enthusiasts of water resources and climate sustainability can appreciate the significance of the East Fork Above Lavon WS SCS Site 13 Dam in mitigating flood risks, supporting local ecosystems, and providing recreational opportunities. With its strategic location and design features, this dam exemplifies the intersection of infrastructure development, environmental conservation, and community resilience in the face of changing climatic 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.
