Crawley Lake Dam dam
Crawley Lake Dam
Crawley Lake Dam, located in Florence, Mississippi, is a privately owned structure that serves primarily for recreational purposes. Completed in 1950, this earth dam stands at a height of 19 feet and spans a length of 710 feet, creating a reservoir with a storage capacity of 152 acre-feet. The dam is situated on the Unt of Hominy Creek, within the jurisdiction of the Mississippi Department of Environmental Quality.
Despite its fair condition assessment as of June 2020, Crawley Lake Dam has been designated as having a high hazard potential, emphasizing the importance of regular inspections and maintenance. The dam's spillway type is listed as uncontrolled, indicating potential risks during periods of high water flow. While the risk assessment for the dam is moderate, it is essential for authorities to continue monitoring and implementing risk management measures to ensure the safety of surrounding communities and the integrity of the structure.
With its scenic location and recreational purpose, Crawley Lake Dam serves as both a valuable resource and potential risk to the area. As enthusiasts of water resources and climate, understanding the complexities of this dam's design, operation, and regulation can provide insights into the broader challenges and opportunities in managing water infrastructure in a changing climate.

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 Crawley Lake Dam
Where does the data for Crawley 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.
