Summary

This impressive structure stands at a height of 135 feet and spans 10,350 feet in length, boasting a storage capacity of 5,097,500 acre-feet and a surface area of 182,490 acres. The dam serves multiple purposes, including hydroelectric power generation, navigation, recreation, and water supply, making it a vital resource for the region.

With a maximum discharge of 290,000 cubic feet per second and a controlled spillway width of 440 feet, Toledo Bend is equipped to manage high volumes of water flow effectively. The dam's hazard potential is classified as high, emphasizing the importance of its risk management measures. Despite its age, Toledo Bend maintains a very high risk assessment rating, demonstrating its ongoing commitment to safety and operational excellence.

Owned by the Tribal Government and regulated by the Federal Energy Regulatory Commission, Toledo Bend plays a crucial role in water resource management in the area. Its strategic location on the Sabine River, along with its diverse capabilities and impressive design, solidify its status as a key player in water infrastructure for both climate and water resource enthusiasts alike.

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.
