Maurice Jones Lake Dam dam
Maurice Jones Lake Dam
Maurice Jones Lake Dam, located in Hinds, Mississippi, is a privately owned structure with a primary purpose of recreation. Completed in 2001, this earth dam stands at a height of 12.5 feet and has a length of 1515 feet, containing a storage capacity of 91 acre-feet. Situated on the UNT of Big Creek, this dam offers a surface area of 10.7 acres for recreational activities.
Managed by the Mississippi Department of Environmental Quality, Maurice Jones Lake Dam is regulated and inspected by the state to ensure its safety and compliance with environmental standards. Although its hazard potential is currently undetermined and its condition is not rated, the dam is considered to have a moderate risk level. With a spillway type of "Uncontrolled" and a maximum discharge capacity of 672 cubic feet per second, the dam provides both recreational opportunities and essential water management functions for the surrounding area.
In the event of an emergency, the dam's Emergency Action Plan status, readiness, and risk management measures are not specifically outlined in the available data. However, Maurice Jones Lake Dam remains a significant water resource infrastructure in Mississippi, contributing to both recreational enjoyment and water management in the region.

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 Maurice Jones Lake Dam
Where does the data for Maurice Jones 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 Undetermined 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.
