Summary
This earth dam stands at a height of 25 feet and has a length of 2950 feet, with a storage capacity of 1061 acre-feet. Despite being uncontrolled, the spillway width of 100 feet allows for a maximum discharge of 1700 cubic feet per second to manage floodwaters effectively.
The dam is state-regulated by the Texas Commission on Environmental Quality (TCEQ), with regular inspections and enforcement to ensure its structural integrity and safety. While the hazard potential and condition assessment are not available, the risk assessment is moderate (3), indicating a need for ongoing monitoring and risk management measures. The dam has three uncontrolled outlet gates and a storage area of 21 acres, serving its primary purpose of flood risk reduction for the local community in East Direct.
For water resource and climate enthusiasts, the Logan Slough Creek WS SCS Site 1 Dam presents an intriguing case study of flood risk management in Texas. With its historical completion date and moderate risk assessment, this earth dam showcases the importance of state regulation and inspection in ensuring the safety and functionality of critical infrastructure. As efforts to address climate change intensify, understanding the design and operation of dams like this one becomes increasingly vital for sustainable water resource management and adaptation to a changing climate.

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.
