Summary
Completed in 1982, this earth dam stands at a height of 73 feet and has a length of 1650 feet, providing essential storage capacity of 6348 acre-feet for water management. The dam is situated on the Lallah Branch river and is regulated by the Texas Commission on Environmental Quality (TCEQ).
With a fair condition assessment as of April 2021, the Paluxy River WS SCS Site 21 Dam plays a vital role in flood risk reduction efforts in the area. The dam's spillway, with a width of 203 feet, helps control water flow during times of high discharge, ensuring the safety of nearby communities. Despite its age, the dam continues to meet inspection and regulatory requirements, highlighting its importance in water resource management and climate resilience in Texas.
As a local government-owned structure, the Paluxy River WS SCS Site 21 Dam serves as a critical asset for water supply and flood control in the region. With a moderate risk assessment rating, it underscores the need for ongoing monitoring and maintenance to ensure its continued effectiveness in protecting the surrounding areas from potential hazards. This dam represents a key component of the state's water infrastructure, showcasing the intersection of water resource management and climate adaptation in addressing the challenges posed by changing environmental conditions.

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.
