Summary

Completed in 1971, this earth dam stands at a height of 24 feet with a length of 1560 feet, creating a storage capacity of 251 acre-feet. It spans the TR-Brushy Creek and is regulated by the Texas Commission on Environmental Quality (TCEQ) with state permitting, inspection, and enforcement in place.

The dam's fair condition assessment in 2018 indicates a moderate risk level, with an inspection frequency of every five years. Equipped with an uncontrolled spillway and two outlet gates, Cedar Creek WS SCS Site 7 Dam plays a critical role in managing water flow and mitigating potential hazards. Despite its hazard potential not being available, this dam continues to safeguard the surrounding area from flooding and supports various water resource management activities, contributing to the overall resilience of the region's water infrastructure.

As a focal point for water resource and climate enthusiasts, Cedar Creek WS SCS Site 7 Dam exemplifies the intersection of engineering, environmental stewardship, and community safety. With its strategic location and multi-functional design, this dam underscores the importance of sustainable water management practices in addressing the challenges posed by climate change and ensuring the long-term viability of water resources in the region. As efforts continue to monitor and maintain the dam's integrity, it remains a key asset in enhancing water security and resilience in Rockwall, Texas, and beyond.

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.
