Coffeyville C. C. Dam dam
Coffeyville C. C. Dam
Located in Coffeyville, Kansas, the Coffeyville C. C. Dam was completed in 1950 with the primary purpose of flood risk reduction along Onion Creek. This privately owned earth dam stands at a height of 20.5 feet and has a hydraulic height of 24 feet, providing a normal storage capacity of 43.9 acre-feet. With a hazard potential rated as high and a fair condition assessment, the dam is regulated by the Kansas Department of Agriculture and undergoes regular inspections to ensure its structural integrity.
The Coffeyville C. C. Dam spans 800 feet in length and has a maximum discharge capacity of 1700 cubic feet per second. Although no spillway type is specified, the dam features a spillway width of 40 feet. The dam's associated structures are listed as none, and it is not under the jurisdiction of the US Army Corps of Engineers. Despite its age, the Coffeyville C. C. Dam continues to play a crucial role in mitigating flood risks in the area and safeguarding the surrounding community from potential water-related disasters.
With its strategic location in Montgomery County, Kansas, the Coffeyville C. C. Dam serves as a vital infrastructure for water resource management and climate resilience efforts in the region. As climate change continues to pose increased threats of extreme weather events, the proper maintenance and monitoring of dams like the Coffeyville C. C. Dam are essential to ensuring the safety and well-being of local residents. From its construction by J. Dale and Steward to its ongoing regulatory oversight by the state, this dam stands as a testament to the importance of proactive water resource management in safeguarding communities against the impacts of climate variability.

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 Coffeyville C. C. Dam
Where does the data for Coffeyville C. C. 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 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.
