Smyth Lake No 2 Dam dam
Smyth Lake No 2 Dam
Smyth Lake No 2 Dam, located in Maverick County, Texas, was completed in 1963 and serves as a crucial water supply source in the region. The dam is an earth-type structure with a height of 16 feet and a length of 2540 feet, providing a storage capacity of 320 acre-feet. Despite not having a spillway, the dam has one outlet gate for water management purposes. The dam is situated on Elm Creek and is under the jurisdiction of the state of Texas.
Although the dam is privately owned and not regulated by the state, regular inspections are conducted to ensure its structural integrity. The dam's hazard potential is not available, but it has been rated as having a high risk level (2). The condition of the dam has not been officially assessed, but it has not been rated as of the last inspection in 1990. Emergency action plans and risk management measures for the dam are not currently available.
For water resource and climate enthusiasts, Smyth Lake No 2 Dam presents an intriguing case study of a privately owned water supply structure in Texas. The dam's historical significance, design specifications, and risk assessment make it a compelling subject for further study and analysis. As water scarcity becomes an increasingly pressing issue, understanding the operation and maintenance of dams like Smyth Lake No 2 Dam is vital for ensuring water security and sustainable resource management in the region.

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 Smyth Lake No 2 Dam
Where does the data for Smyth Lake No 2 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.
