Summary
Completed in 1967, this earth dam stands at a height of 74 feet and spans 1225 feet, with a maximum storage capacity of 4820 acre-feet. With a spillway width of 270 feet and a maximum discharge of 24,866 cubic feet per second, the dam serves as a critical flood risk reduction measure in the region.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Upper Pecan Bayou WS SCS Site 6 Dam plays a vital role in safeguarding the surrounding communities from potential flooding events. While its hazard potential is not available and its condition assessment is not rated, the dam's risk assessment indicates a moderate risk level. With two uncontrolled outlet gates, the dam operates to protect the area from excess water flow during periods of heavy rainfall, demonstrating its importance in water resource management and climate resilience efforts in the region.
As a key component of the water infrastructure system in Callahan County, Texas, the Upper Pecan Bayou WS SCS Site 6 Dam exemplifies the collaborative efforts between local and federal agencies to mitigate flood risks and ensure community safety. With its long history of service since its completion over five decades ago, this dam continues to play a crucial role in protecting the local ecosystem and population from the impacts of extreme weather events, highlighting the intersection of water resource management and climate adaptation strategies in the region.

Dam Data Reference
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.
