Frank Nunley Lake Dam dam
Frank Nunley Lake Dam
Frank Nunley Lake Dam, located in Webb County, Texas, was completed in 1979 with a primary purpose of "Other." This privately owned Earth dam stands at a height of 13 feet and has a length of 1000 feet, providing a storage capacity of 385 acre-feet. Despite its small size, the dam poses a high risk, with a hazard potential of "Not Available" and a risk assessment rating of 2 out of 5.
Situated on the Los Olmos Creek, Frank Nunley Lake Dam does not have a spillway and is not regulated by the state. The dam is primarily used for purposes not specified in the data, and it has not been rated for its condition. With no emergency action plan or inundation maps prepared, the dam's risk management measures remain unknown. While the dam may not capture headlines like larger structures, the unique characteristics and lack of detailed information surrounding Frank Nunley Lake Dam make it an intriguing point of interest for water resource and climate enthusiasts.
Despite the limited data available, the unique design and characteristics of Frank Nunley Lake Dam present an opportunity for further exploration and analysis by water resource and climate enthusiasts. With its location in a high-risk area and lack of comprehensive risk management measures, the dam serves as a reminder of the importance of proper infrastructure maintenance and emergency preparedness in the face of changing climate conditions. As efforts to address water resource challenges continue, Frank Nunley Lake Dam stands as a captivating case study for those interested in the intersection of water management, climate resilience, and infrastructure safety.

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 Frank Nunley Lake Dam
Where does the data for Frank Nunley Lake 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.
