Vesper Lake Dam dam
Vesper Lake Dam
Vesper Lake Dam, located in Dimmit, Texas, serves as a crucial water supply structure for the region. Built in 1940, this earth dam stands at a height of 15 feet and spans a length of 550 feet, with a capacity to store up to 200 acre-feet of water. Situated on Espio Creek, the dam primarily caters to the water needs of the area, providing a normal storage capacity of 56 acre-feet.
Despite being privately owned, Vesper Lake Dam falls under state jurisdiction and is subject to state permitting and inspection requirements. The dam's hazard potential is classified as not available, with a risk assessment rating of high. Although no spillway is present, the dam is equipped with one outlet gate. The condition assessment of the dam is currently not rated, indicating a need for further evaluation and potential risk management measures.
For water resource and climate enthusiasts, Vesper Lake Dam offers a fascinating insight into the infrastructure supporting water supply in the region. With its historical significance dating back to the 1940s, the dam's role in water management and conservation is paramount. As a vital component of the local ecosystem, understanding the operation and maintenance of Vesper Lake Dam is essential for ensuring water security and environmental sustainability in Dimmit, 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 Vesper Lake Dam
Where does the data for Vesper 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.
