Summary
With a dam height of 23 feet and a length of 1000 feet, the earth dam holds a maximum storage capacity of 1050 acre-feet, with a normal storage level of 760 acre-feet. Situated on TR-Post Oak Creek, the dam features uncontrolled spillways and four outlet gates. Despite being privately owned, the dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections and enforcement measures.
The dam's primary purpose is to provide a recreational outlet for water and climate enthusiasts in the region, offering a surface area of 87 acres for various activities. Although the condition assessment is currently not rated, the hazard potential is deemed not available, indicating a moderate risk level. The dam's risk management measures and emergency action plan status are not specified in the data, suggesting a need for further evaluation and preparation. With its historical significance and importance for water storage and leisure, Magnolia Lake Dam stands as a significant landmark in the Fort Worth District, providing both beauty and functionality to the surrounding community.
Overall, Magnolia Lake Dam represents a crucial infrastructure for water resource management and recreational activities in Navarro, Texas. Its age and design make it a valuable piece of history, while its ongoing regulation and maintenance ensure its safety and functionality. As climate change continues to impact water resources, the resilience and effectiveness of dams like Magnolia Lake will be essential in maintaining a sustainable and enjoyable environment for water enthusiasts and local residents 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.
