Summary

Built in 1980, this earth dam stands at 20 feet high and spans 700 feet in length. Its primary purpose is for recreational use, offering visitors a tranquil spot for outdoor activities such as fishing and boating on Prairie Branch.

The dam has a storage capacity of 300 acre-feet, with a normal storage level of 90 acre-feet. It features an uncontrolled spillway with a width of 46 feet and two uncontrolled outlet gates. The dam has undergone structural modifications in 1996 and 2008 to ensure its safety and integrity. Despite being classified as having a moderate risk level, with a hazard potential of "Not Available," the dam's condition has not been officially rated.

Managed by the Texas Commission on Environmental Quality, Azalea Lake Dam serves as a vital resource for both recreational enjoyment and water conservation in the Walker County area. With its picturesque surroundings and strategic design, the dam continues to play a significant role in the local ecosystem and community.

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.
