Summary

Completed in 2000, this dam serves multiple purposes and has a storage capacity of 103 acre-feet with a normal storage of 80 acre-feet. The dam is situated on TR-South Twin Creek and is under the jurisdiction of the state of Texas with permitting and inspection requirements in place.

Despite not having a spillway, Cates Pond No 3 Dam poses a high risk due to its condition being not rated and the hazard potential being not available. The dam has one outlet gate and is not regulated by any federal agency, with primary ownership falling under private entities. With no inundation maps prepared and emergency action plan not updated, there is a need for risk management measures to be implemented to ensure the safety and integrity of the dam for both water resource and climate enthusiasts in the area.

Overall, Cates Pond No 3 Dam stands as a significant structure in the water resource management system of Henderson, Texas, with a complex design and a notable risk assessment. As enthusiasts in the field of water resources and climate, it is important to monitor and address the potential hazards associated with this dam to prevent any adverse impacts on the surrounding environment and communities.

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.
