Hamilton Lake Dam No 1 dam
Hamilton Lake Dam No 1
Hamilton Lake Dam No 1, located in Dimmit, Texas, was completed in 1967 and serves as a crucial water supply source for the region. This private earth dam stands at 18 feet high and stretches 550 feet in length, with a storage capacity of 250 acre-feet. The primary purpose of the dam is to ensure a reliable water source for the surrounding area, particularly during times of drought or increased water demand.
Despite being privately owned, the dam is subject to state permitting and inspection requirements, ensuring its structural integrity and compliance with safety regulations. With a high risk assessment rating of 2, it is important for ongoing risk management measures to be implemented to mitigate potential hazards. With no spillway and a lack of information on hazard potential or condition assessment, it is essential for the dam's owners to prioritize safety and maintenance to prevent any potential risks to the surrounding community and environment.
While the dam may not have a high level of federal oversight, its significance as a water supply source cannot be understated. As climate change continues to impact water resources, dams like Hamilton Lake Dam No 1 play a crucial role in ensuring water security for communities in Texas. It is imperative that the owners of the dam remain vigilant in their maintenance efforts and risk management strategies to safeguard this vital resource for the future.

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 Hamilton Lake Dam No 1
Where does the data for Hamilton Lake Dam 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.
