Summary

This earth dam, with a height of 53 feet and a length of 600 feet, helps regulate the flow of the TR-Waxahachie Creek and provides a storage capacity of 88 acre-feet. Despite its uncontrolled spillway type, the dam has been deemed to have a moderate risk level, indicating the importance of proper monitoring and maintenance.

Managed by the Texas Commission on Environmental Quality (TCEQ), Rodney Green Dam is subject to state regulations and inspections to ensure its safety and functionality. While the dam's condition assessment is currently not rated, its role in maintaining a stable water supply for the surrounding area underscores its significance. The dam's hazard potential is not available, but with the potential for maximum storage and a surface area of 5.5 acres, it is clear that Rodney Green Dam is a vital component of the local water infrastructure.

As climate change continues to impact water resources, structures like Rodney Green Dam become increasingly important for managing water flows and mitigating potential risks. With a designated primary purpose of "Other" and a buttress core type, this dam stands as a testament to human ingenuity in water management. As water resource and climate enthusiasts, understanding the function and significance of Rodney Green Dam is essential for appreciating the complexities of water infrastructure in a changing world.

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.
