Cypress Creek Watershed Structure Y-19a-06 Dam dam
Cypress Creek Watershed Structure Y-19a-06 Dam
The Cypress Creek Watershed Structure Y-19a-06 Dam, also known as Ed Jeffereys Pond, is a vital local government-owned earth dam in Mississippi designed by the USDA NRCS. Completed in 1962, this dam serves the primary purpose of flood risk reduction along the TR- Cypress Creek. With a height of 15 feet and a length of 740 feet, it has a storage capacity of 101 acre-feet and covers a surface area of 8.4 acres within its drainage area of 0.49 square miles.
Managed by the Mississippi Department of Environmental Quality, this dam has a low hazard potential and a moderate risk assessment score of 3. While it currently holds a "Not Rated" condition assessment, it remains regulated, inspected, and enforced by the state to ensure its safety and functionality. The spillway type is uncontrolled, with uncontrolled outlet gates, and is situated in the Yalobusha County city of Coffeeville. Despite its age, the Cypress Creek Watershed Structure Y-19a-06 Dam continues to play a crucial role in mitigating flood risks in the area and maintaining the stability of the surrounding environment.
Enthusiasts of water resources and climate will appreciate the significance of the Cypress Creek Watershed Structure Y-19a-06 Dam as a key component in the flood control infrastructure of Mississippi. With its historical significance dating back to the early 1960s and its ongoing regulatory oversight by the state, this earth dam stands as a testament to the importance of effective water management in the region. Its location on the TR- Cypress Creek, its low hazard potential, and its moderate risk assessment highlight the careful balance between human development and environmental stewardship that is essential in ensuring the resilience of our water resources in the face of climate change.
Dam data reference
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 Cypress Creek Watershed Structure Y-19a-06 Dam
Where does the data for Cypress Creek Watershed Structure Y-19a-06 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.
