Sanderson Canyon Ws Scs Site 6 Dam Reservoir Report
Last Updated: February 11, 2026
Sanderson Canyon WS SCS Site 6 Dam, located in Sanderson, Texas, is a local government-owned structure on the Red Windmill Draw river.
Summary
Completed in 1984, this earth dam stands at a height of 65 feet and has a length of 2790 feet, with a primary purpose of flood risk reduction. The dam has a maximum storage capacity of 5888 acre-feet and a normal storage capacity of 735 acre-feet, serving a drainage area of 16.6 square miles.
The dam features an uncontrolled spillway with a width of 403 feet and outlet gates including a slide (sluice gate) and two uncontrolled gates. With a satisfactory condition assessment as of December 2016, the dam undergoes inspections every five years to ensure its structural integrity and safety. Despite a moderate risk assessment rating of 3, the hazard potential is not available, suggesting a relatively stable and well-maintained structure.
Managed by the Natural Resources Conservation Service, Sanderson Canyon WS SCS Site 6 Dam plays a crucial role in flood protection for the surrounding area. With its strategic design and operational features, this dam exemplifies effective water resource management and climate resilience efforts in the region, showcasing the importance of sustainable infrastructure for safeguarding communities from natural disasters.

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.
