Sowashee Creek Ws Str No 2 Dam dam
Sowashee Creek Ws Str No 2 Dam
Located in Lauderdale, Mississippi, the Sowashee Creek WS Str No 2 Dam, also known as Sowashee 2, was completed in 1979 by the USDA NRCS and is owned by the local government. This earth dam, with a height of 34.9 feet and a storage capacity of 1121 acre-feet, serves the primary purpose of flood risk reduction along Curtis Branch. The dam is regulated by the Mississippi Department of Environmental Quality and is designated as having a high hazard potential with a fair condition assessment as of February 2020.
The Sowashee Creek WS Str No 2 Dam features an uncontrolled spillway with a maximum discharge capacity of 1766 cubic feet per second and a drainage area of 2.56 square miles. The dam's normal storage capacity is 123 acre-feet, covering a surface area of 35 acres. Despite its moderate risk assessment rating, the dam has not undergone any significant modifications since its completion and is inspected every five years to ensure its structural integrity and continued flood protection capabilities. For water resource and climate enthusiasts, the Sowashee 2 Dam presents an intriguing case study in flood risk management and dam safety in the state of 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
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Sowashee Creek Ws Str No 2 Dam
Where does the data for Sowashee Creek Ws Str No 2 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.
