Hamff Lake No 1 Dam dam
Hamff Lake No 1 Dam
Hamff Lake No 1 Dam, located in Lee County, Texas, was completed in 1948 and stands at a height of 20 feet with a length of 895 feet. The dam serves a primary purpose of recreation and boasts a storage capacity of 96 acre-feet, with a normal storage level of 51 acre-feet. Situated on the TR-Rabbs Creek, the dam is classified as an Earth dam with a Buttress core type.
Despite its age, Hamff Lake No 1 Dam has not been rated for its condition and does not have a designated hazard potential. However, it is categorized as having a high risk level of 2. The dam does not have a spillway and features no locks, with only one outlet gate. While the dam is not state-regulated or enforced, it does undergo regular inspections and permitting by the state.
Water resource and climate enthusiasts may be drawn to Hamff Lake No 1 Dam for its historical significance and potential for recreation. With its unique design and location on TR-Rabbs Creek, the dam presents an interesting case study for those interested in dam infrastructure and its impact on the surrounding environment. Further research and study into the risk assessment and management measures of this dam could provide valuable insights for water resource professionals and climate advocates alike.
Dam data reference
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 Hamff Lake No 1 Dam
Where does the data for Hamff Lake No 1 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.
