Stevens Creek A9-6 dam
Stevens Creek A9-6
Stevens Creek A9-6 is a local government-owned structure in Lancaster, Nebraska, designed for flood risk reduction along the Stevens Creek. Completed in 2003, this earth-type dam stands at a height of 31 feet, with a hydraulic height of 30 feet and a structural height of 37 feet. With a storage capacity of 468 acre-feet and a normal storage capacity of 49 acre-feet, this dam serves a vital role in managing water flow and reducing the risk of flooding in the surrounding area.
Located in Rural Lincoln, this dam has been regulated by the Nebraska Department of Natural Resources for state jurisdiction, permitting, inspection, and enforcement. Despite its low hazard potential, the dam is regularly inspected to ensure its satisfactory condition and readiness for emergencies. The last inspection in June 2018 confirmed its sound structure and functionality, meeting guidelines for emergency action plans and risk management measures. With a drainage area of 0.9 square miles and a maximum discharge capacity of 5464 cubic feet per second, Stevens Creek A9-6 plays a crucial role in protecting the local community from potential flooding events.
Overall, Stevens Creek A9-6 stands as a testament to effective water resource management and climate resilience efforts in Nebraska. As a key infrastructure for flood risk reduction along the Stevens Creek, this dam provides essential storage capacity and flood control measures to safeguard the surrounding area. With its satisfactory condition, regular inspections, and state regulation, this structure exemplifies the importance of proactive measures in ensuring water resource sustainability and climate adaptation in the face of changing environmental 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 Stevens Creek A9-6
Where does the data for Stevens Creek A9-6 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.
