Summary

It serves various purposes, including flood control and water storage for the surrounding area. The dam has a normal storage capacity of 8500 acre-feet and a maximum storage of 11700 acre-feet, covering a surface area of 550 acres and draining a 14-square-mile watershed.

Managed by the Texas Commission on Environmental Quality (TCEQ), Lake Creek Dam has a fair condition assessment and undergoes inspections every 5 years. It has one controlled and one uncontrolled outlet gate, with a spillway width of 595 feet. The dam is associated with Manos Creek and has a maximum discharge capacity of 42000 cubic feet per second. Despite not having a hazard potential rating available, the dam's emergency action plan was last revised in 2018 to ensure preparedness in case of any unforeseen events.

Overall, Lake Creek Dam plays a crucial role in water resource management in the region, providing essential services for flood control and water storage. With a long history of serving the community since its completion in 1953, the dam continues to be a vital infrastructure asset that is regularly monitored and maintained to ensure its safety and efficiency in managing water resources in McLennan, Texas.

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.
