Summary
Built in 1980, this earth dam structure stands at 8 feet tall and spans a length of 10,400 feet, with a storage capacity of 536 acre-feet. The reservoir 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 standards.
Despite its small size and lack of a spillway, Prudential Reservoir No 1 poses a high risk (level 2) due to its hazard potential not being available and its condition not being rated. The dam's emergency action plan (EAP) status, inundation maps, and risk management measures are also not documented, raising concerns about its readiness to handle emergencies. With no associated structures and limited operational information, there is a need for further assessment and risk mitigation strategies to safeguard this critical water resource in the event of a disaster.
In the shadow of the TR-Caranchua Creek, Prudential Reservoir No 1 serves as a vital source of water for irrigation in the region, highlighting the importance of proper maintenance and oversight to protect both the environment and the community's water supply. As climate change and extreme weather events continue to pose threats to water resources, ensuring the resilience and safety of infrastructure like Prudential Reservoir No 1 is crucial for sustainable water management in Texas.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
