Coro Lake dam
Coro Lake
Coro Lake in Memphis, Tennessee, is a privately owned reservoir that serves as a popular recreational spot. Managed by the Tennessee Safe Dams Program, the dam on Horn Lake Creek was completed in 1951 and stands at a hydraulic height of 12.8 feet and a structural height of 17 feet. With a storage capacity of 931 acre-feet and a surface area of 95 acres, the lake offers ample space for outdoor activities such as boating, fishing, and picnicking.
Despite its significant hazard potential and unsatisfactory condition assessment, Coro Lake continues to attract visitors seeking a natural escape within Shelby County. The dam's spillway type is listed as uncontrolled, and the last inspection in December 2018 revealed the need for improvement. As a moderate risk site with a risk rating of 3, ongoing risk management measures are essential to ensure the safety and sustainability of this beloved water resource in the region.
While the dam lacks certain emergency preparedness protocols such as an updated EAP and inundation maps, the presence of the Tennessee Safe Dams Program as the regulatory agency indicates a commitment to enforcing state regulations and conducting regular inspections. With its tranquil waters and picturesque surroundings, Coro Lake remains a valued asset for the community, offering both recreational opportunities and a reminder of the importance of proactive dam safety measures 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 Coro Lake
Where does the data for Coro Lake 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.
