Summary
Built in 1976 by the USDA NRCS, this earth dam stands at a height of 34 feet and spans 1887 feet in length, providing a storage capacity of 2566 acre-feet. Despite being regulated by the Texas Commission on Environmental Quality and inspected regularly, its hazard potential and condition assessment remain unspecified, hinting at potential vulnerabilities that may need addressing.
With a primary purpose of flood risk reduction, this dam also caters to fire protection, stock, and small fish pond needs for the local community. Its single slide gate outlet provides control over water release, ensuring efficient management of the 4.44 square mile drainage area it serves. While it lacks a spillway, the dam's strategic location and design play a vital role in safeguarding the surrounding area from inundation during periods of high discharge. The risk assessment categorizes it as high, emphasizing the importance of continued monitoring and maintenance to uphold its protective capabilities.
Representing a partnership between local government and federal agencies, Attoyac Bayou WS SCS Site 15 Dam illustrates the collaborative efforts put forth in managing water resources and mitigating flood risks. As part of the Fort Worth District under the USDA NRCS, this dam stands as a testament to engineering excellence and environmental stewardship. Despite its age, the dam's significance in safeguarding the community and environment underscores the critical role it plays in water resource management and climate resilience efforts in the region.

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.
