Stevens Creek A2-1 dam
Stevens Creek A2-1
Stevens Creek A2-1, located in Lancaster, Nebraska, is a vital earth dam designed by Olsson Associates for flood risk reduction along the TR-Stevens Creek. Completed in 2005, this dam stands at a height of 25 feet with a structural height of 32 feet and a length of 905 feet. With a storage capacity of 256 acre-feet and a drainage area of 0.5 square miles, Stevens Creek A2-1 plays a crucial role in managing water levels and protecting the surrounding area from potential flooding.
Owned by the local government and regulated by the Nebraska Department of Natural Resources, Stevens Creek A2-1 has a high hazard potential but was assessed to be in satisfactory condition as of October 2020. The dam is equipped with emergency action plans and undergoes regular inspections to ensure its integrity and functionality. With a maximum discharge capacity of 3087 cubic feet per second, this structure is essential for mitigating flood risks in the region and maintaining water resource sustainability in the face of changing climate patterns.
As a key component of the flood risk reduction infrastructure in rural Lincoln, Stevens Creek A2-1 not only provides critical protection for the local community but also serves as a symbol of proactive water resource management. Its strategic location and efficient design make it a valuable asset for safeguarding against potential disasters and ensuring the long-term resilience of the area. With ongoing monitoring and maintenance, this earth dam continues to play a crucial role in water resource management and climate adaptation efforts in Nebraska.

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 A2-1
Where does the data for Stevens Creek A2-1 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.
