Sanderson Canyon Ws Scs Site 2 Dam Reservoir Report
Last Updated: February 11, 2026
Sanderson Canyon WS SCS Site 2 Dam, located in Pecos, Texas, is a crucial structure owned by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ).
Summary
Completed in 1980, this earth-type dam stands at a height of 90 feet and has a storage capacity of 11,789 acre-feet, serving primarily for flood risk reduction along Dry Creek. The dam's spillway, with a width of 254 feet, helps control maximum discharges of up to 35,422 cubic feet per second.
The dam's structural integrity was last assessed in January 2017, receiving a fair condition rating. Although the hazard potential is noted as not available, the risk assessment deems the dam to have a moderate risk level. The emergency action plan (EAP) status and risk management measures for the dam are currently unspecified, highlighting potential areas for further evaluation and preparedness. With a history of inspections and regulatory compliance, Sanderson Canyon WS SCS Site 2 Dam plays a vital role in water resource management and climate resilience efforts in the region.

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.
