Mckinnon Lake Dam dam
Mckinnon Lake Dam
Mckinnon Lake Dam, located in Macon, Mississippi, stands as a testament to the conservation efforts of the USDA NRCS, who designed this earth dam in 1965 for the primary purpose of recreation. This privately-owned dam on Skinner Creek reaches a height of 12 feet and has a storage capacity of 70-acre feet. Despite its low hazard potential and moderate risk assessment, the dam remains ungraded in terms of condition assessment, with no recent inspection data available. The Mississippi Department of Environmental Quality oversees state regulation, permitting, inspection, and enforcement related to this structure.
Serving as a tranquil spot for recreational activities, Mckinnon Lake Dam provides a scenic retreat for water resource and climate enthusiasts to enjoy nature's beauty. With its uncontrolled spillway and outlet gates, the dam presents a peaceful haven for fishing, boating, and wildlife observation. While the dam's condition is not currently rated, its low hazard potential and moderate risk assessment indicate a stable structure that contributes to the region's water management and environmental conservation efforts.
As part of the Vicksburg District, this earth dam continues to offer a valuable recreational resource for the community, with the potential for further risk management measures to enhance its long-term sustainability. With its historical significance dating back to the mid-20th century, Mckinnon Lake Dam remains a symbol of responsible land use and water conservation in Oktibbeha County, Mississippi.
Dam data reference
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.
Plan around the weather

About Mckinnon Lake Dam
Where does the data for Mckinnon 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 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.
