Bose Dam dam
Bose Dam
Bose Dam, located in Harlan, Nebraska, is a privately owned structure regulated by the Nebraska Department of Natural Resources. Built in 1960, this earth dam stands at a height of 16.4 feet and has a storage capacity of 72.6 acre-feet, primarily serving flood risk reduction purposes along the TR-Twin Creek. Despite its low hazard potential, the dam's condition assessment has been marked as poor, raising concerns about its long-term sustainability.
With a surface area of 9.7 acres and a drainage area of 0.62 square miles, Bose Dam plays a crucial role in managing water resources in the region. However, the lack of recent modifications and proper maintenance has led to its deteriorating condition. The dam's inspection frequency is set at every 5 years, indicating the need for regular monitoring and potential rehabilitation efforts to ensure its continued functionality and safety for the surrounding communities.
As a focal point for water resource and climate enthusiasts, Bose Dam serves as a reminder of the importance of proper infrastructure management and maintenance in the face of changing environmental conditions. With state jurisdiction and regulatory oversight in place, stakeholders must work together to address the dam's poor condition assessment and mitigate any potential risks associated with its operation. By prioritizing the dam's rehabilitation and implementing necessary risk management measures, Bose Dam can continue to fulfill its vital role in flood risk reduction and water resource management for years to come.

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 Bose Dam
Where does the data for Bose 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.
