Summary
This earth dam stands at a height of 30 feet and stretches 1333 feet in length, with a capacity of 1740 acre-feet for storage and a drainage area of 3.1 square miles. Despite its age, the dam is in good condition, with a hazard potential that is not currently available, making it a reliable asset for managing water resources in the area.
Managed by local government authorities and regulated by the Texas Commission on Environmental Quality (TCEQ), the Attoyac Bayou WS SCS Site 8 Dam serves multiple purposes beyond flood risk reduction, including fire protection and support for stock and small fish ponds. With a single slide gate for outlet control, the dam has not experienced significant modifications over the years and has not been rated for its condition. However, its high risk assessment indicates the need for ongoing monitoring and maintenance to ensure its continued effectiveness in protecting the surrounding community from potential water-related hazards.
Water resource and climate enthusiasts interested in the Attoyac Bayou WS SCS Site 8 Dam will appreciate its strategic location and design features, such as its buttress core type and lack of spillways. The dam's association with the Natural Resources Conservation Service highlights the importance of sustainable water management practices in the region. Overall, this dam stands as a testament to the collaboration between federal, state, and local agencies in safeguarding water resources and mitigating flood risks for the benefit of the community and the environment.

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.
