Retama Tank Dam dam
Retama Tank Dam
Retama Tank Dam, located in McMullen, Texas, serves as a vital water supply infrastructure in the region. Completed in 1969, this earth dam stands at a height of 15 feet and spans a length of 470 feet, with a storage capacity of 143 acre-feet. The dam is primarily designed for water supply purposes, drawing water from the TR-Guadalupe Creek to meet the needs of the local community.
Despite its essential role in water resource management, Retama Tank Dam currently lacks a spillway, which may pose a potential hazard in case of heavy rainfall or flooding events. Its condition assessment remains unrated, highlighting the need for regular inspections and maintenance to ensure its safety and functionality. With a high risk rating of 2, there is a pressing need for risk management measures to be implemented to safeguard the dam and the surrounding area from any potential threats.
As water resource and climate enthusiasts, it is crucial to monitor and support initiatives that enhance the resilience of dams like Retama Tank Dam in the face of changing environmental conditions. By advocating for proper maintenance, risk assessment, and emergency preparedness measures, we can contribute towards ensuring the sustainable management of water resources and the protection of communities relying on these critical infrastructures.

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 Retama Tank Dam
Where does the data for Retama Tank Dam 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.
