Summary

This earth dam stands at a height of 28 feet and stretches 3550 feet in length, providing a storage capacity of 3494 acre-feet for water resource management in the region. With a spillway width of 96 feet and a maximum discharge capacity of 2770 cubic feet per second, the dam serves multiple purposes including fire protection, stock watering, and recreational activities.

Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Cedar Creek WS SCS Site 16a Dam has a fair condition assessment and a moderate risk rating. Equipped with slide and uncontrolled gates, the dam plays a crucial role in maintaining water levels and ensuring the safety of surrounding communities. While the hazard potential is not available, regular inspections every five years help to identify any maintenance needs and ensure the dam's integrity for continued operation.

As a part of the flood risk reduction infrastructure in the area, Cedar Creek WS SCS Site 16a Dam contributes to the overall water management efforts in Rockwall, Texas. With its strategic location and design, this dam serves as a vital resource for water storage, flood control, and recreational activities, highlighting the importance of sustainable water resource management and climate resilience in the region.

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.
