Sanderson Canyon Ws Scs Site 1 Dam Reservoir Report
Last Updated: February 11, 2026
Located in Sanderson, Texas, the Sanderson Canyon WS SCS Site 1 Dam is a vital structure owned and regulated by the local government.
Summary
Completed in 1986, this earth dam stands at a height of 50 feet and has a structural height of 79.4 feet, serving primarily for flood risk reduction along an unnamed tributary. With a storage capacity of 6019 acre-feet and a drainage area of 19.58 square miles, this dam plays a crucial role in controlling water flow and mitigating potential flood risks in the region.
Managed by the Natural Resources Conservation Service, the dam features an uncontrolled spillway with a width of 204 feet and outlet gates for water release. Inspected periodically for safety and operational efficiency, the structure was last assessed in January 2017 and was found to be in satisfactory condition. While the hazard potential is not available, the risk assessment indicates a moderate level of risk, emphasizing the importance of ongoing monitoring and maintenance to ensure the dam's continued effectiveness in flood control and water resource management.
With its significant storage capacity and strategic location, the Sanderson Canyon WS SCS Site 1 Dam stands as a critical infrastructure for flood risk reduction in Brewster County, Texas. Supported by state regulatory agencies and designed to withstand potential hazards, this dam exemplifies the importance of sustainable water resource management and climate resilience in safeguarding communities and ecosystems against the impacts of extreme weather events.

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.
