Oestmann Dam dam
Oestmann Dam
Oestmann Dam, located in Stella, Nebraska, serves as a crucial structure for grade stabilization along the TR-MUDDY CREEK. Completed in 2009, this private-owned Earth dam stands at a height of 27 feet, with a total length of 500 feet. With a storage capacity of 68.4 acre-feet and a drainage area of 0.22 square miles, Oestmann Dam plays a vital role in managing water resources in Nemaha County.
The dam's low hazard potential and satisfactory condition assessment make it a reliable infrastructure for flood control and water management. Under the regulatory oversight of the Nebraska Department of Natural Resources, Oestmann Dam undergoes regular inspections to ensure its structural integrity and operational effectiveness. Its strategic location and design contribute to the overall resilience of the surrounding ecosystem and community, providing essential benefits for water resource and climate enthusiasts in the region.
As a key component of the local water management system, Oestmann Dam not only facilitates grade stabilization but also contributes to the overall environmental sustainability of Nemaha County. With its effective design and operational protocols in place, the dam serves as a testament to responsible water resource management practices. For enthusiasts in the field of water resources and climate, Oestmann Dam represents a successful example of infrastructure that balances human needs with ecological considerations in a dynamic and changing environment.

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 Oestmann Dam
Where does the data for Oestmann Dam 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.
