Summary

Designed by Powell & Powell, this concrete structure serves as a flood risk reduction measure for the Woody Branch river/stream. With a maximum storage capacity of 475 acre-feet, the dam plays a crucial role in managing water flow and reducing the risk of flooding in the surrounding area.

Owned by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Woody Branch Dam is inspected every five years to ensure its structural integrity and overall safety. The dam features an uncontrolled spillway with a width of 725 feet and two uncontrolled outlet gates. The condition assessment conducted in June 2014 deemed the dam to be in satisfactory condition, with a moderate risk level assigned. This vital infrastructure serves as a crucial component of water resource management in the region, protecting the community from potential flood events while also providing recreational opportunities for residents and visitors alike.

As a multi-arch concrete dam, Woody Branch Dam not only serves its primary purpose of flood risk reduction but also contributes to the overall water management and conservation efforts in the area. With its strategic location and design, this dam plays a crucial role in ensuring the safety and well-being of the local population while also enhancing the ecological balance of the surrounding environment. Through regular inspections, risk assessments, and maintenance measures, Woody Branch Dam continues to fulfill its role as a key asset in the sustainable management of water resources and climate resilience in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
