Greenbriar Lake Dam dam
Greenbriar Lake Dam
Greenbriar Lake Dam, located in Smith County, Texas, was completed in 1903 and serves as a recreational water resource for the surrounding area. The dam, primarily made of earth with a buttress core, stands at a height of 29 feet and stretches 450 feet in length. With a storage capacity of 1260 acre-feet and a surface area of 85 acres, the dam regulates the flow of TR-Indian Creek, providing a serene environment for outdoor enthusiasts.
Maintained and regulated by the Texas Commission on Environmental Quality (TCEQ), Greenbriar Lake Dam underwent modifications in 1976 and 2010 to enhance its hydraulic capabilities. The dam features an uncontrolled spillway with a width of 15 feet and is equipped with two uncontrolled and two valve outlet gates. Despite being classified as having a fair condition assessment, the dam presents a moderate risk level, prompting regular inspections every five years to ensure its structural integrity and safety standards are met.
With Louie Gohmert (R) as the Congressional Representative for the district, the Greenbriar Lake Dam continues to provide recreational opportunities for visitors while upholding state regulatory requirements. As a vital water resource in the region, the dam's ability to control water flow and provide a picturesque setting for outdoor activities makes it a significant asset for both the local community and climate enthusiasts 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 Greenbriar Lake Dam
Where does the data for Greenbriar 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.
