Spring Creek 25-A dam
Spring Creek 25-A
Spring Creek 25-A is a local government-owned Earth dam located in Custer County, Nebraska, designed by USDA NRCS. Completed in 1972, it serves the primary purpose of flood risk reduction on Stump Creek. With a dam height of 41 feet and a drainage area of 10.1 square miles, the dam has a storage capacity of 2842 acre-feet and a maximum discharge of 4700 cubic feet per second. Despite its low hazard potential and satisfactory condition assessment, the dam is subject to state regulation and inspection by the Nebraska Department of Natural Resources.
The dam's structure consists of stone core and soil foundation, with a hydraulic height of 40 feet and a structural height of 42 feet. It has a length of 1208 feet and a surface area of 5 acres. The dam is located in a rural area near Cozad, Nebraska, and is under the jurisdiction of the Kansas City District of the US Army Corps of Engineers. The last inspection in May 2019 deemed the dam to be in satisfactory condition, with an inspection frequency of every 5 years.
While Spring Creek 25-A may not pose a high risk, it plays a crucial role in managing flood risks in the area and protecting downstream communities. Water resource and climate enthusiasts can appreciate the engineering and regulatory efforts that go into maintaining the safety and functionality of this essential infrastructure for flood control and water management 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 Spring Creek 25-A
Where does the data for Spring Creek 25-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.
