Hartmann Dam 3892 dam
Hartmann Dam 3892
Located in Steinauer, Nebraska, the Hartmann Dam 3892 is a private-owned earth dam primarily constructed for recreational purposes along the TR-Sampson Branch of Turkey Creek. Completed in 2016, this dam stands at a height of 20.7 feet, with a hydraulic height of 19.51 feet and a structural height of 24.25 feet. With a storage capacity of 152.9 acre-feet, the dam covers a surface area of 12.2 acres and serves as a popular spot for outdoor activities.
Managed by the Nebraska Department of Natural Resources (NE DNR), the Hartmann Dam 3892 is regulated, inspected, and enforced by the state to ensure its safety and compliance with regulations. Despite being classified as a low hazard potential structure, the dam has a satisfactory condition assessment as of May 2017. In the event of emergencies, it is crucial for the dam to have an Emergency Action Plan (EAP) in place to mitigate risks and protect surrounding areas from potential flooding incidents.
With a Congressman representing the area in Congressional District 03, Nebraska, the Hartmann Dam 3892 plays a significant role in providing recreational opportunities for locals and visitors alike. As a vital water resource in Johnson County, this dam serves as an essential component of the community's landscape, contributing to the conservation and sustainable management of water resources in the region.

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 Hartmann Dam 3892
Where does the data for Hartmann Dam 3892 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.
