Summary
Built in 1953 by the USDA NRCS, this earth dam serves multiple purposes including flood risk reduction, fire protection, stock, small fish pond, and recreation. With a height of 35 feet and a length of 1350 feet, the dam has a storage capacity of 640 acre-feet and covers a surface area of 16.7 acres. The dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its safety and functionality.
This dam plays a vital role in managing water resources in the area, providing flood protection and recreational opportunities for local residents. The dam is designed with an uncontrolled spillway and two outlet gates, allowing for the controlled release of water during heavy rainfall events. The risk assessment for the dam is moderate, with a hazard potential that is currently not available. While the condition of the dam has not been rated, it is regularly inspected for any maintenance or repairs that may be needed to ensure its continued functionality and safety for the surrounding community.
As a key structure in the Fort Worth District managed by the Natural Resources Conservation Service, the Lower East Fork Laterals WS SCS Site 11 Dam represents a collaboration between local government agencies and federal entities to protect and manage water resources in the region. Its strategic location on the TR-Hillside Diversion Terrace stream highlights its importance in mitigating flood risks and providing essential water management support for the area. With a rich history dating back to the 1950s, this dam continues to serve as a critical infrastructure for water resource and climate enthusiasts in the region.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
