Summary
This earth dam stands at a height of 27 feet with a length of 500 feet, providing a storage capacity of 1424 acre-feet. The dam, regulated by the Texas Commission on Environmental Quality (TCEQ), features an uncontrolled spillway with a width of 150 feet and a maximum discharge of 18000 cubic feet per second.
Despite being classified as having a moderate risk level, the dam's condition assessment remains unrated, with the last inspection conducted in February 2016. The hazard potential of Boynton Lake Dam is not available, and there is no Emergency Action Plan (EAP) in place. Owned by the local government and situated within the Fort Worth District, this structure plays a crucial role in water resource management in the region, highlighting the intersection of infrastructure, water supply, and environmental stewardship in the face of changing climate patterns.
For water resource and climate enthusiasts, Boynton Lake Dam represents a significant engineering feat that underscores the importance of effective dam management and maintenance in safeguarding communities and ecosystems. As discussions around water security and climate resilience continue to evolve, understanding the intricacies of structures like Boynton Lake Dam becomes essential for informed decision-making and sustainable water resource management in a changing world.

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.
