Coxs Creek Dam dam
Coxs Creek Dam
Coxs Creek Dam, located in Calhoun County, Texas, serves as a critical water supply infrastructure for the region. Completed in 1956, this earth dam stands at a height of 20 feet and has a storage capacity of 3,250 acre-feet. The dam spans a length of 3,700 feet and is primarily designed for water supply purposes, reflecting its importance in meeting the water needs of the local community.
Managed by a private entity, Coxs Creek Dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections and enforcement measures to ensure its structural integrity and operational efficiency. The dam features a spillway width of 285 feet and outlet gates for controlled and uncontrolled water release. With a maximum discharge capacity of 6,721 cubic feet per second, the dam plays a crucial role in managing water flow and mitigating flood risks in the area.
Despite its age, Coxs Creek Dam has undergone structural modifications in 1985 to enhance its resilience and performance. With a hazard potential that is not available and a condition assessment that is not rated, ongoing risk management measures are in place to monitor and address any potential safety concerns. This dam represents a vital piece of infrastructure in the region's water resource management system, highlighting the importance of maintaining and safeguarding such critical assets for long-term sustainability.

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 Coxs Creek Dam
Where does the data for Coxs Creek 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.
