Mcrainey Lake Dam dam
Mcrainey Lake Dam
Mcrainey Lake Dam, located in Rankin, Mississippi, serves as a vital recreational resource in the area. This private-owned earth dam spans 400 feet in length and stands at a height of 18 feet, providing a storage capacity of 144 acre-feet. The dam, primarily used for recreation, boasts a spillway type of 'Uncontrolled' and has been assessed with a low hazard potential and a moderate risk assessment rating.
Managed by the Mississippi Department of Environmental Quality, Mcrainey Lake Dam is state-regulated, inspected, and enforced to ensure its structural integrity and safety. Although last inspected in 2004, the dam's condition remains unrated, with no emergency action plan in place. Despite these factors, the dam continues to be a valuable resource for the local community, offering opportunities for outdoor activities and water-based recreation along the UNT of Steen Creek.
As water resource and climate enthusiasts, the Mcrainey Lake Dam presents a fascinating case study in dam management and risk assessment. While the dam's current risk level is classified as moderate, the lack of recent inspections and emergency preparedness measures highlight the importance of ongoing monitoring and maintenance to ensure the safety of both the structure and the surrounding area. This unique earth dam serves as a reminder of the delicate balance between water resource management and the need for sustainable recreational amenities in communities like Rankin, Mississippi.

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 Mcrainey Lake Dam
Where does the data for Mcrainey 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.
