Summary
The earth dam, with a height of 9 feet and a length of 8690 feet, provides a storage capacity of 928 acre-feet and a normal storage of 405 acre-feet. Despite being primarily designed for recreation, the levee is also state-regulated and regularly inspected by the Texas Commission on Environmental Quality (TCEQ) to ensure its safety and effectiveness.
The levee, situated off CH-Austin Bayou, is owned privately and falls under the jurisdiction of the state of Texas. With no spillway and a hazard potential deemed "Not Available," the structure poses a moderate risk, as reflected in its risk assessment ranking of "High (2)." While the condition assessment remains "Not Rated," the levee's emergency action plan (EAP) was last revised in 2009, indicating a proactive approach to emergency preparedness. Despite some gaps in data, Mccullough Lake Levee stands as a significant feature in the local landscape, providing both recreational enjoyment and critical water resource management.
Managed by the Fort Worth District of the US Army Corps of Engineers, Mccullough Lake Levee plays a crucial role in water resource management and flood control efforts in the region. The levee's strategic location and design contribute to the overall resilience of the area, mitigating potential risks and ensuring the safety of nearby communities. With ongoing state inspections and regulatory oversight, Mccullough Lake Levee remains a key asset in the region's water infrastructure, highlighting the importance of sustainable water resource management in the face of changing climate patterns and environmental challenges.

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.
