Mission Creek 6-A dam
Mission Creek 6-A
Mission Creek 6-A is a vital flood risk reduction structure located in Pawnee, Nebraska, designed by the USDA NRCS and regulated by the Nebraska Department of Natural Resources. Completed in 1977, this earth dam stands at a height of 36 feet and has a maximum storage capacity of 892 acre-feet, serving the primary purpose of flood risk reduction along Mission Creek. With a drainage area of 3.1 square miles and a normal storage capacity of 180 acre-feet, this structure plays a crucial role in mitigating potential flooding events in the region.
The dam, with a length of 1517 feet and a hydraulic height of 32 feet, has a satisfactory condition assessment as of June 2016 and a low hazard potential. While it currently does not have an Emergency Action Plan (EAP) in place or inundation maps prepared, the structure undergoes inspections every five years to ensure its continued effectiveness. Managed by the Natural Resources Conservation Service, Mission Creek 6-A is a key component in the flood management infrastructure of the area, providing essential protection to the surrounding communities and ecosystems.
Located in a strategic spot within the Mission Creek watershed, this flood risk reduction structure not only safeguards the local area from potential inundation but also contributes to the overall resilience of the region against the impacts of extreme weather events and climate change. As part of the network of water resource management systems in Nebraska, Mission Creek 6-A stands as a testament to the ongoing efforts to balance the needs of human development with the protection of natural resources, ensuring a sustainable and secure future for all stakeholders involved.

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 Mission Creek 6-A
Where does the data for Mission Creek 6-A 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.
