Jennings Lake Dam dam
Jennings Lake Dam
Jennings Lake Dam, located in Sulphur Springs, Texas, is a privately owned earth dam completed in 1964 for fire protection, stock, and as a small fish pond. The dam is situated on TR-Rock Creek and stands at a height of 17.4 feet with a length of 2200 feet, providing a storage capacity of 117 acre-feet. Despite its primary purpose, the dam also serves for recreational activities in the area, offering a serene setting for visitors to enjoy.
Managed by the Texas Commission on Environmental Quality (TCEQ), Jennings Lake Dam has undergone modifications in 2003 to enhance its structural integrity. The dam features an uncontrolled spillway with a width of 35 feet and an outlet gate for water release. Regular inspections have been conducted, with the last assessment in December 2015, indicating a moderate risk level. While the dam's condition is not currently rated, its risk management measures ensure the safety of the surrounding community and the environment.
For water resource and climate enthusiasts, Jennings Lake Dam represents a vital infrastructure supporting various purposes while also highlighting the importance of dam safety and risk assessment. The dam's presence on Rock Creek contributes to the local ecosystem and provides a valuable resource for water storage and recreational activities. Monitoring and maintenance efforts continue to uphold the dam's integrity, ensuring its continued function and safety in the face of changing environmental conditions.

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 Jennings Lake Dam
Where does the data for Jennings 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.
