Haynes Lake Dam dam
Haynes Lake Dam
Haynes Lake Dam, located in Ramsey Springs, Mississippi, was completed in 1968 by the USDA NRCS and serves as a recreational resource in Stone County. The dam stands at a height of 14 feet and has a maximum storage capacity of 90 acre-feet. It is classified as an earth dam with a buttress core type and soil foundation, designed for low hazard potential.
The dam is state-regulated by the Mississippi Department of Environmental Quality, with permitting, inspection, and enforcement responsibilities falling under state jurisdiction. The primary purpose of Haynes Lake Dam is recreation, providing opportunities for outdoor activities in the surrounding area. With a moderate risk assessment rating, the dam is considered to have a moderate level of risk associated with its operation and maintenance.
Despite its low hazard potential, the condition assessment of Haynes Lake Dam is currently not rated, indicating a need for further evaluation of its structural integrity. The dam features an uncontrolled spillway and outlet gates, with no associated locks. As a key feature in the TR-Bridge Creek-OS river system, the dam plays a crucial role in managing water resources and supporting the local ecosystem. For water resource and climate enthusiasts, Haynes Lake Dam offers a fascinating glimpse into the intersection of engineering, recreation, and environmental stewardship in 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 Haynes Lake Dam
Where does the data for Haynes 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.
