Cypress Creek #9 dam
Cypress Creek #9
Cypress Creek #9, also known as Cypress Creek Watershed Dam 9, is a privately owned earthen dam located in Weakley, Tennessee. Constructed in 1963 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the TRIBWRIGHT BRANCH river or stream. With a hydraulic height of 18 feet and a structural height of 21 feet, this dam has a normal storage capacity of 49 acre-feet and a maximum storage capacity of 354 acre-feet, covering a surface area of 16.5 acres.
Maintained and regulated by the Tennessee Safe Dams Program, Cypress Creek #9 has a high hazard potential and a satisfactory condition assessment as of its last inspection in February 2021. Despite its moderate risk level, the dam has not been modified in recent years and does not currently have outlet gates for controlled release of water. With a history of successful flood risk reduction and a dedicated regulatory agency, Cypress Creek #9 remains a crucial component of water resource management in the region.
For water resource and climate enthusiasts, Cypress Creek #9 presents an intriguing case study of private dam ownership and regulation in Tennessee. With its earth core and stone foundation, this dam showcases the importance of proactive maintenance and regular inspections to ensure community safety and effective flood risk reduction. As climate change continues to impact water resources, understanding the management and maintenance of dams like Cypress Creek #9 is essential for sustainable water resource management in the face of evolving environmental challenges.

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 #9
Where does the data for Cypress Creek #9 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.
