Cleary Lake Dam dam
Cleary Lake Dam
Cleary Lake Dam, located in Rankin, Mississippi, is a privately owned structure that serves as a vital resource for recreation in the area. Built in 1950, this earth dam stands at a height of 13.5 feet and spans a length of 430 feet, creating a reservoir with a storage capacity of 174 acre-feet. The dam is situated on Hawkins Branch, a tributary that contributes to a drainage area of 0.14 square miles.
Despite its primary purpose for recreation, Cleary Lake Dam is classified as having a high hazard potential, with a fair condition assessment as of March 2020. The dam features an uncontrolled spillway and does not have outlet gates. Regular inspections are conducted, with the last one taking place in September 2020, indicating a 5-year inspection frequency. The dam is regulated by the Mississippi Department of Environmental Quality and is subject to state permitting, inspection, and enforcement.
Water resource and climate enthusiasts will find Cleary Lake Dam to be a noteworthy structure in Mississippi, offering both recreational opportunities and a critical component of water management in the region. Its history, design, and management provide valuable insights into the intersection of human infrastructure with natural resources, highlighting the importance of careful oversight and maintenance to ensure the safety and sustainability of water-related structures.
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.

About Cleary Lake Dam
Where does the data for Cleary 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 High 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.
