Summary

Built in 1953 by the USDA NRCS, this earth dam boasts a height of 32 feet and a storage capacity of 565 acre-feet. With a primary purpose of flood risk reduction, the dam also serves other functions such as fire protection, recreational use, and stock or small fish pond maintenance.

Situated on the TR-East Fork Trinity River, this dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes state permitting, inspection, and enforcement to ensure its structural integrity and compliance with safety standards. Despite being categorized as having a high risk potential, the East Fork Above Lavon WS SCS Site 24 Dam has not been rated for its current condition. The dam does not feature a spillway and has one outlet gate for water management.

As water resource and climate enthusiasts observe this dam, they can appreciate the collaborative efforts between local government agencies and the USDA NRCS to manage flood risks and provide essential water storage in Collin County, Texas. With its historical significance dating back to the 1950s, this dam represents a crucial piece of infrastructure in the region's water resource management system.

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.
