About this dam

Humbird

Humbird, also known as Halls Creek, is a gravity dam located in Clark, Wisconsin, specifically on the East Fork Halls Creek. This structure, completed in 1871, serves primarily for recreational purposes, offering opportunities for outdoor enthusiasts to enjoy the surrounding area. With a height of 19 feet and a length of 423 feet, Humbird has a normal storage capacity of 127 acre-feet and a maximum discharge of 1,225 cubic feet per second.

Despite its age, Humbird has been well-maintained, with a fair condition assessment as of May 2020. The dam has a low hazard potential and is regulated by the Wisconsin Department of Natural Resources, which oversees its permitting, inspection, and enforcement. The risk assessment for Humbird indicates a very high risk level, reflecting the importance of ongoing monitoring and management of the structure to ensure its continued safety and functionality for the surrounding community.

While Humbird may not be the largest or most high-profile dam, its historical significance and role in providing recreational opportunities make it a valuable asset for the local area. As climate change continues to impact water resources, structures like Humbird will play a crucial role in managing and conserving these vital resources for future generations. It is essential for water resource and climate enthusiasts to stay informed and engaged with the maintenance and regulation of dams like Humbird to ensure their continued effectiveness and safety in the face of evolving environmental 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 Humbird

Where does the data for Humbird 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.
