Summary
This private earth dam stands at a height of 32 feet and has a length of 1056 feet, providing a storage capacity of 550 acre-feet. Despite its age, the dam is regularly inspected and maintained by the Texas Commission on Environmental Quality to ensure its structural integrity and safety.
The dam, situated on the TR-SAND BRANCH river or stream, is under state jurisdiction and regulation, with the TCEQ overseeing permitting, inspection, and enforcement. Although the spillway type is listed as 'None', the dam has one outlet gate for water release. The risk assessment for Duke Lake Dam is classified as high (2), indicating potential hazards that need to be managed and monitored. While the condition assessment is currently not rated, the dam's risk management measures and emergency preparedness plans are not specified in the available data.
For water resource and climate enthusiasts, Duke Lake Dam presents an interesting case study of a privately owned structure that plays a crucial role in local water management and ecosystem support. The dam's historical significance, combined with its ongoing regulatory oversight and risk assessment, highlights the complex interplay between human infrastructure and natural resources in the face of changing environmental conditions. As efforts continue to ensure the safety and functionality of Duke Lake Dam, it serves as a reminder of the importance of sustainable water resource management practices in the context of climate variability and increasing demands on water systems.

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.
