About this dam

Hayden Lake

Hayden Lake is a picturesque water body located in Kootenai County, Idaho, with a rich history dating back to its completion in 1910. This private lake is regulated by the Idaho Department of Water Resources, ensuring that it is properly maintained and monitored for the benefit of the local community and environment. With a storage capacity of 38,000 acre-feet and a surface area of 4,200 acres, Hayden Lake plays a crucial role in the region's water resource management.

The dam at Hayden Lake stands at a height of 13.36 feet and is primarily of earth and stone construction, with a spillway width of 50 feet. Despite its low hazard potential and fair condition assessment, Hayden Lake still poses a moderate risk, with a moderate risk assessment score of 3. The lake is a popular destination for outdoor enthusiasts, offering opportunities for boating, fishing, and wildlife observation. With its beautiful surroundings and important role in water resource management, Hayden Lake is a valuable asset to the community and a key player in the region's climate resilience efforts.

Overall, Hayden Lake is a well-regulated and maintained body of water in Idaho, providing both recreational enjoyment and essential water resource management services. As a privately owned lake with state oversight, Hayden Lake exemplifies the balance between human enjoyment and environmental stewardship. With its historical significance, moderate risk assessment, and diverse range of activities, Hayden Lake is a must-visit destination for water resource and climate enthusiasts looking to appreciate the beauty and importance of this natural resource.

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 Hayden Lake

Where does the data for Hayden Lake 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.
