Summary
With a height of 12 feet and a length of 500 feet, the dam holds a maximum storage capacity of 50 acre-feet, providing water for a surface area of 9 acres and draining a 2.5 square mile watershed area. The dam is regulated by the state of Texas, with state permitting and inspection in place.
The dam, situated on Magnus Branch, features an uncontrolled spillway with a width of 75 feet and an uncontrolled outlet gate. While the hazard potential and condition assessment of the dam are not available, the risk assessment categorizes it as moderate. The Emergency Action Plan (EAP) for the dam was last revised in May 2011, and the dam has an inspection frequency of 5 years. Despite not being under the ownership or funding of federal agencies, Electro Lake Dam continues to serve as a recreational resource for the local community.
Overall, Electro Lake Dam stands as a historic structure in Tyler County, Texas, combining both functional and leisurely aspects as a private Earth dam. With its scenic surroundings and moderate risk level, the dam remains a key feature for water resource and climate enthusiasts to explore and appreciate in the Fort Worth District. Its presence on Magnus Branch adds to the diverse landscape of water infrastructure in the region, showcasing the importance of sustainable management and regulation for such vital resources.

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.
