About this dam

Hartington Dam

Hartington Dam, located in Cedar County, Nebraska, is a critical infrastructure project designed by Olsson Associates and completed in 2015 for flood risk reduction on the TR-Norwegian Creek. This earth dam stands at a height of 26 feet and has a hydraulic height of 24.2 feet, providing a storage capacity of 112 acre-feet. With a surface area of 1.16 acres and a drainage area of 0.24 square miles, Hartington Dam plays a crucial role in managing water resources in the region.

Managed by the local government and regulated by the Nebraska Department of Natural Resources, Hartington Dam is inspected regularly to ensure its structural integrity and safety. The dam has a satisfactory condition assessment and a high hazard potential, emphasizing the importance of its role in protecting the surrounding area from potential flooding events. The dam's emergency action plan and risk management measures are in place to mitigate any potential risks and ensure the safety of the community.

Adrian Smith (R) represents the area in Congress, highlighting the political significance of Hartington Dam in the region. With its completion in 2015, the dam has become a key component in the water resource management system, providing flood risk reduction and enhancing water security for the residents of Hartington and beyond. As a vital piece of infrastructure, Hartington Dam showcases the intersection of engineering, climate resilience, and environmental stewardship in safeguarding communities against water-related challenges.

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.

FAQ

About Hartington Dam

Where does the data for Hartington 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 High 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.
