Cox Dam dam
Cox Dam
Cox Dam, located in Hendricks County, Indiana, is a private Earth dam completed in 1996 primarily for recreational purposes. With a dam height of 23.5 feet and a storage capacity of 339 acre-feet, this structure is situated on an unnamed tributary of the Sallust Branch. Despite being privately owned, the dam is regulated by the Indiana Department of Natural Resources, with state inspections and enforcement in place to ensure its safety and compliance with regulations.
The dam's spillway, with a width of 30 feet, is uncontrolled, allowing for a maximum discharge of 255 cubic feet per second. The hazard potential of Cox Dam is considered significant, with a fair condition assessment as of October 2010. The risk assessment for the dam is moderate, highlighting the importance of ongoing risk management measures to protect the surrounding area from potential flooding events. While the dam's emergency action plan and inundation maps status are not provided, the regular inspections and maintenance efforts contribute to the overall safety and stability of Cox Dam for both recreational and environmental purposes.
Water resource and climate enthusiasts interested in Cox Dam will find its location and design details, along with its risk assessment and condition assessment, to be key points of interest. The dam's role in providing recreational opportunities and its regulatory oversight by the state of Indiana add to its significance in the local water resource management landscape. Cox Dam serves as a reminder of the importance of maintaining and monitoring dam infrastructure to ensure public safety and environmental protection in the face of changing climate 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 Cox Dam
Where does the data for Cox 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 Significant 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.
