Calvin Powell Dam dam
Calvin Powell Dam
Calvin Powell Dam, located in Grand Saline, Texas, is a private-owned structure primarily designed for recreation purposes. This earth dam, standing at a height of 14 feet and a length of 300 feet, holds a normal storage capacity of 8 acre-feet and a maximum storage of 13 acre-feet. The dam features an uncontrolled spillway with a width of 23 feet and two uncontrolled outlet gates.
Managed by the Texas Commission on Environmental Quality (TCEQ), Calvin Powell Dam has a fair condition assessment as of April 2021. The dam is subject to regular inspections every two years to ensure its safety and structural integrity. With a moderate risk assessment rating, the dam poses a certain level of risk, but measures are in place to manage and mitigate any potential hazards.
For water resource and climate enthusiasts, Calvin Powell Dam serves as a recreational hub in Van Zandt County, offering opportunities for outdoor activities and enjoyment. Its presence along the Grand Saline Creek adds to the scenic beauty of the area while also highlighting the importance of proper dam maintenance and regulation to ensure the safety of surrounding communities and the preservation of water resources.

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 Calvin Powell Dam
Where does the data for Calvin Powell 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.
