Sanderson Canyon Ws Scs Site 4 Dam Reservoir Report
Last Updated: February 11, 2026
Sanderson Canyon WS SCS Site 4 Dam, located in Sanderson, Texas, is a locally owned earth dam designed by Benham, Blair in 1986 for flood risk reduction along the TR-Sanderson Canyon stream.
Summary
With a dam height of 51 feet and a structural height of 73 feet, it serves as a crucial infrastructure in the area with a storage capacity of 4,057 acre-feet and a maximum discharge of 51,081 cubic feet per second. The dam's spillway is uncontrolled, with a width of 428 feet, and it is inspected every five years by the Texas Commission on Environmental Quality (TCEQ).
The dam's primary purpose is flood risk reduction, with a satisfactory condition assessment as of December 2016. It has a drainage area of 10.42 square miles and a normal storage capacity of 528 acre-feet. The dam is equipped with a slide and two uncontrolled outlet gates for water release. Despite its moderate hazard potential, the risk assessment for the dam is considered to be moderate, with no documented risk management measures in place. Overall, Sanderson Canyon WS SCS Site 4 Dam plays a crucial role in managing water resources and mitigating flood risks 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.
