Prudential Reservoir No 1 dam
Prudential Reservoir No 1
Prudential Reservoir No 1, located in Jackson, Texas, is a private water resource managed for irrigation purposes by the USDA NRCS. 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.

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.
- 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.
- 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.
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, environmental 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.

About Prudential Reservoir No 1
Where does the data for Prudential Reservoir No 1 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Not Available hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
