Frd No 7 dam
Frd No 7
Frd No 7, also known as North Black Vermillion WS Site 7, is a significant earth dam located in Frankfort, Kansas, designed by the USDA NRCS. Completed in 1977, this dam serves the primary purpose of flood risk reduction along the Little Timber Creek-TR river/stream, with a hydraulic height of 25 feet and a structural height of 28 feet. With a total length of 1870 feet and a storage capacity of 181.31 acre-feet, Frd No 7 plays a crucial role in mitigating potential flood hazards in the region.
Despite being classified as having a low hazard potential, Frd No 7 has a moderate risk assessment rating, indicating some level of risk associated with its operation. The dam does not have any outlet gates and features an uncontrolled spillway with a width of 40 feet. While the condition assessment is currently listed as "Not Rated," ongoing monitoring and maintenance are essential to ensure the continued effectiveness and safety of Frd No 7. With a strong focus on flood risk reduction, this earth dam remains a vital infrastructure asset in safeguarding the surrounding community from potential water-related disasters.
As part of the flood risk reduction strategy in Kansas, Frd No 7 stands as a testament to the collaborative efforts between local government agencies and the USDA NRCS in addressing water resource and climate challenges. With its operational history dating back to over four decades, this earth dam continues to play a crucial role in managing floodwaters and protecting the residents of Marshall County. As water resource and climate enthusiasts, it's essential to recognize the significance of infrastructure like Frd No 7 and the ongoing need for proactive monitoring and maintenance to ensure its continued functionality in the face of changing environmental conditions.
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 Frd No 7
Where does the data for Frd No 7 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.
