Earl Pinham Lake Dam dam
Earl Pinham Lake Dam
Earl Pinham Lake Dam, located in Picayune, Mississippi, was completed in 1965 by the USDA NRCS and serves as a vital water resource for the area. The dam, primarily used for recreation, stands at a height of 16 feet and has a storage capacity of 100 acre-feet. It is classified as an earth dam with a buttress core and soil foundation, providing essential flood control measures for the TR- George Branch river.
Managed by the Mississippi Department of Environmental Quality, Earl Pinham Lake Dam is subject to state regulations, inspections, and enforcement to ensure its structural integrity and safety. The dam's spillway is uncontrolled, and the outlet gates are also uncontrolled, highlighting the need for ongoing monitoring and risk assessment. The dam's hazard potential is currently labeled as undetermined, with a moderate risk level assigned.
Water resource and climate enthusiasts will appreciate the strategic importance of Earl Pinham Lake Dam in managing water flow and protecting the surrounding area from potential flooding events. As a private-owned structure, the dam plays a crucial role in preserving the ecological balance of the Pearl River in Mississippi. With its historical significance and ongoing state oversight, Earl Pinham Lake Dam remains a key player in the region's water management efforts, embodying the intersection of human infrastructure and natural resource conservation.

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 Earl Pinham Lake Dam
Where does the data for Earl Pinham 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.
