Toposhaw Watershed Structure Y-27-15 Dam dam
Toposhaw Watershed Structure Y-27-15 Dam
The Toposhaw Watershed Structure Y-27-15 Dam, also known as the Shelton Dam, is a local government-owned earth dam located in Grenada, Mississippi. Designed by the USDA NRCS and completed in 1974, this dam plays a crucial role in flood risk reduction along the Toposhaw Creek. With a dam height of 8 feet and a storage capacity of 194 acre-feet, the structure is regulated and inspected by the Mississippi Department of Environmental Quality to ensure its safety and functionality.
Despite being classified as having a low hazard potential, the Toposhaw Watershed Dam serves as a vital component of the region's water resource management. The dam's uncontrolled spillway and outlet gates help to regulate water flow during periods of high discharge, contributing to the overall flood risk reduction efforts in the area. With a moderate risk assessment rating of 3, ongoing risk management measures are in place to address any potential concerns and ensure the dam's continued effectiveness in protecting the surrounding communities.
As part of the Mobile District of the USACE, the Toposhaw Watershed Structure Y-27-15 Dam exemplifies the collaboration between federal and state agencies in safeguarding water resources and mitigating climate-related challenges. Its role in managing water flow, reducing flood risks, and maintaining environmental quality highlights the importance of sustainable infrastructure in addressing the impacts of climate change on local communities.

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 Toposhaw Watershed Structure Y-27-15 Dam
Where does the data for Toposhaw Watershed Structure Y-27-15 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.
