Summary

Constructed in 1985 by Winslow & Associates Inc, this earth dam stands at a height of 20 feet and spans 1400 feet in length, holding a storage capacity of 2376 acre-feet. The dam, situated on Panther Branch, is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections and enforcement to ensure its structural integrity.

The dam's primary purpose of irrigation supports the surrounding agricultural activities, while also offering recreational opportunities for the community. With a spillway width of 490 feet and a maximum discharge capacity of 13101 cubic feet per second, the dam is equipped to manage excess water flow effectively. Despite its moderate risk assessment rating, the dam's hazard potential is currently not available, and its overall condition remains unrated. Emergency action plans have been prepared and updated periodically to meet safety guidelines, ensuring the dam's resilience in the face of potential risks.

Lake Woodlands Dam stands as a testament to effective water resource management, combining functionality with recreational value for the local residents. As a privately-owned structure, it plays a crucial role in maintaining water supply for irrigation while offering a scenic backdrop for leisure activities. With ongoing inspections and risk management measures in place, the dam continues to serve as a valuable asset in the region's water infrastructure, highlighting the importance of sustainable practices in safeguarding our water resources amidst changing climate patterns.

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.
