Summary

This private-owned Earth dam stands at a height of 8 feet and has a length of 990 feet, with a storage capacity of 260 acre-feet. Situated on the Parvin Branch off CH-TR, this structure is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections, enforcement, and permitting to ensure its safety and compliance with state regulations.

The dam's hazard potential is considered not available, with a high risk assessment rating of 2, indicating the importance of proper risk management measures. Despite lacking a spillway, the dam features one outlet gate for controlled water release. While the condition assessment is not rated, the dam is subject to state jurisdiction and enforcement, reflecting the commitment to maintaining its integrity and safeguarding the surrounding area. As water resource and climate enthusiasts, understanding the operational and safety aspects of Caldwell Dam contributes to the broader conversation on sustainable water management and infrastructure resilience.

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.
