Potacocawa Watershed Structure Y-31a-01 Dam dam
Potacocawa Watershed Structure Y-31a-01 Dam
Potacocawa Watershed Structure Y-31a-01 Dam, also known as Perkins Lake, is a local government-owned dam located in Avalon, Mississippi. Built in 1962 by the USDA NRCS, this earth dam stands at a height of 30 feet and serves as a flood risk reduction structure along the Bobmore Branch river. With a storage capacity of 530 acre-feet, the dam plays a crucial role in managing water flow and reducing the risk of flooding in the area.
Managed by the Mississippi Department of Environmental Quality, Potacocawa Watershed Structure Y-31a-01 Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and functionality. Despite being classified as having a low hazard potential and a moderate risk assessment, the dam's condition is currently not rated. Nonetheless, the dam's primary purpose of flood risk reduction highlights its importance in protecting the surrounding community and the environment from potential water-related disasters.
With its earth dam construction and buttress core type, Potacocawa Watershed Structure Y-31a-01 Dam showcases the collaboration between federal and state agencies in safeguarding water resources and mitigating climate-related risks. As water resource and climate enthusiasts, understanding and monitoring the condition of such structures is crucial for ensuring the sustainability and resilience of our water infrastructure in the face of changing environmental conditions.

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 Potacocawa Watershed Structure Y-31a-01 Dam
Where does the data for Potacocawa Watershed Structure Y-31a-01 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.
