Mrs S O Tharp Lake dam
Mrs S O Tharp Lake
Mrs S O Tharp Lake, located in Murphy, Mississippi, is a privately owned water reservoir with a primary purpose designated as "Other". The dam, constructed in 1966 by the USDA NRCS, is an earth dam with a height of 8 feet and a length of 5420 feet, designed to control the flow of the TR- Sunflower River. The reservoir has a storage capacity of 152 acre-feet and a low hazard potential, making it a vital resource for water management in the region.
Managed by the Vicksburg District of the US Army Corps of Engineers, Mrs S O Tharp Lake serves as a crucial water source for the area, with a spillway type classified as "Uncontrolled" and an outlet gate also designated as "Uncontrolled". Despite its moderate risk assessment rating, the lake has not been assigned a Dam Safety Action Classification (DSAC) date, indicating that it is currently under close monitoring for any potential hazards. The condition assessment of the dam is noted as "Not Rated", suggesting that further evaluation may be necessary to ensure its structural integrity and safety for the surrounding community.
Although Mrs S O Tharp Lake is not regulated by the state and does not require permitting or inspections, its importance for water resource management in the region cannot be understated. With a rich history dating back to the 1960s, this reservoir continues to play a vital role in mitigating the impact of climate change and ensuring a sustainable water supply for the residents of Humphreys County, 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.
Plan around the weather

About Mrs S O Tharp Lake
Where does the data for Mrs S O Tharp Lake 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.
