Spring Creek 7-C dam
Spring Creek 7-C
Spring Creek 7-C is a crucial flood risk reduction structure located in Johnson, Nebraska. Built in 1971 by USDA NRCS, this earth dam stands at 32 feet tall and spans 897 feet in length, with a storage capacity of 437 acre-feet. Despite its relatively low hazard potential, the dam is regularly inspected by the Nebraska Department of Natural Resources to ensure its structural integrity and satisfactory condition.
Managed by the local government, Spring Creek 7-C plays a vital role in protecting the surrounding area from potential flooding events. With a drainage area of 1.5 square miles and a maximum discharge capacity of 985 cubic feet per second, this structure serves as a key component in the flood control system for the region. Its presence is a testament to the collaborative efforts between federal and state agencies in safeguarding water resources and enhancing climate resilience in the area.
As part of the broader water management infrastructure in Nebraska, Spring Creek 7-C not only provides flood protection but also contributes to the conservation and sustainable use of water resources. With its satisfactory condition and regular inspections, this earth dam exemplifies the importance of proactive maintenance and monitoring to ensure the continued effectiveness of water management structures in the face of changing climate conditions.

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 Spring Creek 7-C
Where does the data for Spring Creek 7-C 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.
