Summary

Standing at a height of 8 feet with a length of 3000 feet, this dam impounds water from the Off Ch-Neches River, creating a surface area of 6 acres and a drainage area of 95 square miles. The dam has a normal storage capacity of 25 acre-feet and a maximum storage of 45 acre-feet, with an uncontrolled spillway width of 50 feet.

While the dam's hazard potential and condition assessment are not available, it is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes state inspection, enforcement, and permitting. The last inspection was conducted in 2009 and the dam is classified as having a moderate risk level. With three uncontrolled outlet gates, Lake Jackson Dam provides essential water resource management in the region and contributes to the recreational activities in the area. The dam's association with the Fort Worth District of the US Army Corps of Engineers highlights its significance in water resource and climate management efforts.

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.
