Sanderson Canyon Ws Scs Site 10 Dam Reservoir Report
Last Updated: February 11, 2026
Sanderson Canyon WS SCS Site 10 Dam, located in Terrell County, Texas, stands as a vital structure for flood risk reduction along the TR-THREEMILE DRAW river or stream.
Summary
Built in 1980 by Blom Engineering, this earth dam reaches a height of 56 feet and spans 2200 feet in length, with a storage capacity of 2441 acre-feet. The dam's spillway, which is uncontrolled, has a width of 178 feet and can handle a maximum discharge of 24500 cubic feet per second.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the dam is inspected every 5 years to ensure its structural integrity. The most recent assessment in 2017 deemed the dam to be in satisfactory condition, with a moderate risk rating of 3. The primary purpose of the Sanderson Canyon WS SCS Site 10 Dam is to protect the surrounding area from flooding, making it a crucial asset in safeguarding the community and water resources in the region.
With its stone core and soil foundation, this dam exemplifies the importance of proper water resource management and climate resilience in the face of increasing environmental challenges. As water resource and climate enthusiasts, understanding the intricacies of structures like the Sanderson Canyon WS SCS Site 10 Dam is essential in advocating for sustainable practices and policies to protect our communities and natural ecosystems.

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.
