Summary

This reservoir, regulated by the Texas Commission on Environmental Quality (TCEQ), sits on Choctaw Creek and serves as a critical source of raw water for the power plant's operations. With a capacity of 109 acre-feet and a surface area of 8.7 acres, this reservoir plays a vital role in ensuring the plant's water needs are met.

The dam, standing at a height of 16.5 feet and a length of 2430 feet, features an uncontrolled spillway with a width of 50 feet. The reservoir's condition assessment, conducted in April 2021, deemed it to be in satisfactory condition with a moderate risk level. With a drainage area of 0.01 square miles and a maximum discharge of 684 cubic feet per second, this reservoir is equipped to handle water flow efficiently and effectively.

While specific details about the year of completion and any modifications are not provided, the Panda Sherman Power Raw Water Reservoir continues to serve as a crucial infrastructure for the power plant's water supply needs. As water resource and climate enthusiasts, understanding and monitoring the condition and management of such reservoirs are essential for ensuring sustainable water usage and environmental conservation in the region.

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.
