Harmoney Dam dam
Harmoney Dam
Harmoney Dam, located in Buffalo County, Nebraska, is a privately owned structure that serves the primary purpose of flood risk reduction along the TR-Wood River. Completed in 1960, this earth dam stands at a height of 16.2 feet and has a storage capacity of 62.2 acre-feet, with a normal storage level of 20 acre-feet. With a low hazard potential, Harmoney Dam is regulated and inspected by the Nebraska Department of Natural Resources to ensure its safety and effectiveness in flood control.
The dam, constructed with a stone core and resting on a soil foundation, spans a length of 281 feet and covers a surface area of 6.2 acres, serving a drainage area of 0.5 square miles. Despite its low hazard potential, Harmoney Dam is subject to regular inspections every five years to assess its condition and ensure its continued functionality in mitigating flood risks in the area. The dam's location in the Kansas City District and its designation as a flood risk reduction structure highlight its importance in safeguarding the surrounding community from potential water-related disasters.
In the realm of water resource and climate management, Harmoney Dam plays a crucial role in protecting the Buffalo County area from flooding events by providing a reliable barrier along the TR-Wood River. As a privately owned structure, it showcases the collaborative effort between private entities and state regulatory agencies in managing water resources effectively. With its strategic design and regular inspections, Harmoney Dam stands as a key asset in the region's flood control infrastructure, demonstrating the importance of proactive measures in addressing climate-related challenges for the community's safety and well-being.

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 Harmoney Dam
Where does the data for Harmoney 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.
