Wiedeman Dam dam
Wiedeman Dam
Wiedeman Dam, located in Lancaster, Nebraska, was completed in 1967 by USDA NRCS and is primarily used for fire protection, stock watering, and as a small fish pond. This private earth dam stands at a height of 18 feet and has a hydraulic height of 16 feet, with a length of 600 feet. The dam has a normal storage capacity of 24 acre-feet and a maximum storage of 61 acre-feet, serving as a crucial water resource in the region.
Managed by the Nebraska Department of Natural Resources, Wiedeman Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and functionality. With a low hazard potential and fair condition assessment, the dam poses minimal risk to the surrounding area. The last inspection in April 2018 confirmed its structural integrity, and regular inspections are carried out every five years to monitor its performance and address any maintenance needs. Despite its modest size, the dam plays a vital role in water management and conservation efforts along the TR-Little Nemaha River.
Located in the Kansas City District and under the jurisdiction of the Nebraska DNR, Wiedeman Dam serves as a key infrastructure for water resource management in the region. With its strategic placement and purposeful design, the dam contributes to the overall ecosystem health and resilience, showcasing the importance of sustainable water management practices in mitigating the impacts of climate change. As a vital component of the local water supply system, Wiedeman Dam stands as a testament to the ongoing efforts to safeguard water resources and adapt to changing climatic conditions for the benefit of the community and the 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 Wiedeman Dam
Where does the data for Wiedeman 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.
