Summary
Completed in 1970, this earth dam stands at a height of 24 feet and stretches 1790 feet in length, with a storage capacity of 1094 acre-feet. While primarily built for flood risk reduction, it also serves purposes such as fire protection, stock or small fish pond, and recreation, showcasing its multifunctional role in water resource management.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Little Elm and Laterals WS SCS Site 19 Dam plays a crucial role in ensuring the safety and protection of the surrounding area. With a high risk assessment rating and limited hazard potential, this dam is an essential infrastructure for water resource and climate enthusiasts to monitor and study. Despite not having a spillway, the dam is equipped with one outlet gate for controlled water release, underscoring the importance of proper maintenance and inspection protocols to uphold its structural integrity and operational efficiency.
As part of the Fort Worth District under the US Army Corps of Engineers, Little Elm and Laterals WS SCS Site 19 Dam stands as a testament to the collaborative efforts between federal, state, and local agencies in safeguarding communities against potential water-related emergencies. With its strategic location and design features, this dam exemplifies the commitment to sustainable water management practices and serves as a valuable asset in the overall resilience of the water infrastructure system in Texas.

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.
