Summary

This earth dam stands at a height of 31 feet and has a length of 1153 feet, providing a storage capacity of 678 acre-feet and a surface area of 18 acres. Despite its primary purpose for flood risk reduction, the dam serves multiple functions including fire protection, stock maintenance, and recreation.

With a drainage area of 1.31 square miles, East Fork Above Lavon WS SCS Site 29 Dam plays a vital role in managing water flow in the region. Although it does not have a spillway, it is equipped with a flap gate for controlled release of water. The dam's structural integrity is maintained through periodic inspections, with the last assessment conducted in May 2013. While its hazard potential is not available, the dam's risk assessment is rated as high (2), highlighting the importance of effective risk management measures.

As a state-regulated structure under the jurisdiction of the Texas Commission on Environmental Quality (TCEQ), East Fork Above Lavon WS SCS Site 29 Dam underscores the collaborative efforts between local government and federal agencies in ensuring water resource management and safety. Enthusiasts of water resources and climate resilience can appreciate the significance of this dam in safeguarding the surrounding community from potential flood hazards while also supporting various water-related activities in the area.

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.
