Casper Creek dam
Casper Creek
Casper Creek, also known as the Edmund Orgill Dam, is a local government-owned structure located in Millington, Tennessee. Built in 1967 by the USDA NRCS, this earth dam on Casper Creek serves a primary purpose of recreation, providing a surface area of 61.4 acres and a normal storage capacity of 370 acre-feet. With a hydraulic height of 24.2 feet and a structural height of 31.6 feet, the dam stands at 1690 feet in length and has a drainage area of 0.86 square miles.
Managed by the Tennessee Safe Dams Program, Casper Creek Dam has a high hazard potential but is currently assessed as being in satisfactory condition as of June 2020. Despite its risk level, the dam's risk assessment is moderate, with a DSAC assigned date yet to be determined. The dam has no associated locks or outlet gates and features an uncontrolled spillway type. While there are no inundation maps prepared or emergency action plans updated, the dam is inspected annually to ensure its safety and functionality for the surrounding community.
Casper Creek Dam, with its serene recreational offerings and essential water resource management capabilities, stands as a testament to responsible dam construction and maintenance in the face of changing climate conditions. Positioned within the Memphis District of Tennessee, this structure exemplifies the importance of state-regulated and inspected dams in safeguarding communities against potential hazards and ensuring the sustainable utilization of water resources for future generations.

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 Casper Creek
Where does the data for Casper Creek 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.
