Ellison Dam dam
Ellison Dam
Ellison Dam, located in Chickasaw, Mississippi, was completed in 2002 and serves as a key recreational spot in the area. This private dam, with a height of 18 feet and a length of 900 feet, has a storage capacity of 125 acre-feet and covers a surface area of 13.2 acres. It is primarily used for recreational purposes, attracting water resource and climate enthusiasts to enjoy activities such as fishing, boating, and hiking in its vicinity.
Managed by the Mississippi Department of Environmental Quality, Ellison Dam is state-regulated and regularly inspected to ensure its safety and compliance with regulatory standards. With a low hazard potential and a moderate risk assessment rating, the dam poses no imminent threat but still requires monitoring and maintenance to uphold its condition. The dam's spillway, classified as uncontrolled, has a maximum discharge rate of 145 cubic feet per second, allowing for controlled release of excess water to prevent flooding in the surrounding UNT of Chewawah Creek.
Ellison Dam's construction and design reflect a commitment to both safety and recreational value, making it a popular destination for outdoor enthusiasts in Mississippi. As a foundational element in the local water resource infrastructure, the dam's role in providing recreational opportunities while managing water flow underscores its importance in supporting both the environment and the community.

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 Ellison Dam
Where does the data for Ellison 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 Low 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.
