Summary
Owned privately, this earth dam stands at a height of 23 feet and has a structural length of 521 feet. With a maximum storage capacity of 115 acre-feet and a normal storage of 95 acre-feet, the dam creates a surface area of 15 acres and serves the Tongue River.
Despite being a privately owned structure, Seale Lake Dam is subject to state permitting and inspection. The dam has not been rated for its condition assessment and its hazard potential is not available. With a high risk assessment level of 2, there are no emergency action plans in place or updated inundation maps prepared. The dam does not have a spillway and its maintenance and risk management measures are not specified at this time.
For water resource and climate enthusiasts, Seale Lake Dam serves as an interesting example of a privately owned recreational dam in Texas. With its modest size and limited information available on its risk assessment and management, the dam presents opportunities for further study and potential improvements to ensure its safety and functionality for both recreational and water resource purposes.

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.
