Upper Salt Creek 2-A dam
Upper Salt Creek 2-A
Upper Salt Creek 2-A is a local government-owned earth dam located in Lancaster, Nebraska, designed by USDA NRCS and completed in 1955 for flood risk reduction purposes. This structure stands at a height of 36 feet, with a hydraulic height of 22 feet and a length of 740 feet, providing a maximum storage capacity of 257 acre-feet. The dam, situated on TR-Salt Creek, serves the primary purpose of flood risk reduction and is regulated by the Nebraska Department of Natural Resources.
With a hazard potential rated as low and a satisfactory condition assessment as of September 2016, Upper Salt Creek 2-A is an essential component of the local water resource management infrastructure. The dam covers a drainage area of 0.9 square miles and has a normal storage capacity of 16 acre-feet, helping to mitigate potential flooding events in the region. Additionally, the dam has a maximum discharge capacity of 1077 cubic feet per second, ensuring effective water flow control during peak flow periods.
As a vital structure in the flood risk reduction strategy for the area, Upper Salt Creek 2-A has been inspected periodically, with the last assessment conducted in September 2016. Its location, design, and capacity make it a key asset in managing water resources and climate-related challenges in the region. With its low hazard potential and satisfactory condition, this dam plays a crucial role in safeguarding the community against potential flood risks.

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 Upper Salt Creek 2-A
Where does the data for Upper Salt Creek 2-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.
