Summary

Built in 1959, this earth dam stands at a height of 22 feet and spans a length of 580 feet, with a storage capacity of 80 acre-feet. The dam is situated on TR-Duck Creek and is regulated by the Texas Commission on Environmental Quality (TCEQ), ensuring it meets state inspection and enforcement standards.

Despite its small surface area of 6 acres, Sampeck Lake Dam poses a high risk (level 2) due to its unknown hazard potential and lack of condition assessment. While it does not have a spillway, it is equipped with one outlet gate. The dam's risk management measures, emergency action plan, and inundation maps are all marked as unavailable, raising concerns for potential emergency scenarios and public safety.

For water resource and climate enthusiasts, Sampeck Lake Dam presents an intriguing case study of a privately-owned recreation dam in need of improved risk assessment and management. Its location on TR-Duck Creek and limited storage capacity highlight the importance of proper regulatory oversight and emergency preparedness in ensuring the safety of both the structure and surrounding community. As discussions on climate resilience and water resource management continue, the state-regulated dam serves as a reminder of the critical role that infrastructure plays in maintaining water security and mitigating potential hazards.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
