Cox Lake Dam dam
Cox Lake Dam
Cox Lake Dam, located in Anderson, Texas, along Mitchell Branch, is a privately owned structure designed by C L MOON INC and completed in 1974. The primary purpose of this Earth-type dam is water supply, with a storage capacity of 131 acre-feet and a maximum height of 16 feet. Despite being unlisted for hazard potential and not rated for condition assessment, it is subject to state permitting and inspection requirements.
With a risk assessment rating of "High (2)", Cox Lake Dam presents a potential concern for water resource and climate enthusiasts. This Earth-type dam with a buttress core stands at 16 feet tall and spans 635 feet in length. Although it lacks a spillway, it does feature one outlet gate. The dam's location in Anderson, Texas, within the Fort Worth District, highlights its significance in providing water supply to the surrounding area.
As a key water resource infrastructure in Anderson, Texas, Cox Lake Dam serves a critical role in water supply management. Its construction in 1974 underscores its longstanding contribution to the local community's water needs. While its hazard potential and condition assessment are not readily available, the dam's state-regulated status, permitting, and inspection signify ongoing efforts to ensure its safety and effectiveness in water supply management.

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 Cox Lake Dam
Where does the data for Cox 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.
