Summary
Built in 1969 by USDA NRCS, this earth dam stands at a height of 36 feet and spans 2800 feet in length, with a maximum storage capacity of 1800 acre-feet. The dam serves multiple purposes, including flood risk reduction and recreation, and is regulated by the Texas Commission on Environmental Quality (TCEQ).
With a drainage area of 1.1 square miles and a spillway width of 80 feet, Town Branch WS SCS Site 1 Dam has a maximum discharge capacity of 5974 cubic feet per second. The dam's structure, made of stone core and supported by rock and soil foundations, has been deemed satisfactory in condition assessments as of April 2021. While the hazard potential and risk assessment are labeled as "Not Available" and "Moderate (3)" respectively, the dam's operational integrity and compliance with state regulations ensure its continued effectiveness in managing water resources in the region.
Overall, Town Branch WS SCS Site 1 Dam stands as a crucial piece of infrastructure for flood control and water management in Madisonville, Texas. Its construction and ongoing maintenance highlight the importance of sustainable water resource management in the face of climate challenges, making it a key site of interest for water resource and climate enthusiasts alike.

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.
