Herman Dam dam
Herman Dam
Herman Dam, located in Washington, Nebraska, is a private earth dam constructed in 1952 on the TR-Missouri River. With a height of 28 feet and a length of 860 feet, the dam has a storage capacity of 106 acre-feet and serves the primary purpose of water resource management. Despite being regulated and inspected by the Nebraska Department of Natural Resources, the dam is categorized as having a significant hazard potential with a poor condition assessment.
Water resource and climate enthusiasts will find Herman Dam a fascinating structure to study due to its location on the Missouri River and its role in managing water resources in the region. The dam's poor condition assessment and significant hazard potential raise concerns about its structural integrity and the potential risks it poses to the surrounding area in case of failure. Additionally, the dam's limited storage capacity and drainage area highlight the importance of proper maintenance and monitoring to ensure its continued functionality.
As a key component of the local water infrastructure, Herman Dam's condition and management are crucial for ensuring water security and mitigating potential risks. The dam's history, design, and regulatory oversight provide valuable insights into the challenges and considerations involved in maintaining and operating such critical infrastructure in the face of changing climate conditions and increasing water demand. Enthusiasts interested in water resource management and climate adaptation will find Herman Dam a compelling case study for exploring the intersection of infrastructure resilience and environmental sustainability.

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 Herman Dam
Where does the data for Herman 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 Significant 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.
