About this dam

Henkin Pond Dam

Henkin Pond Dam, located in Custer, Michigan, was completed in 1966 with a primary purpose of recreation. This earth dam stands at 18 feet in height and spans 300 feet, creating a storage capacity of 66 acre-feet. Situated on a tributary to Freeman Creek, the dam's low hazard potential and moderate risk assessment make it an intriguing structure for water resource and climate enthusiasts to explore.

Managed by a private owner, Henkin Pond Dam has not been subject to state regulation or inspection. Despite its age, the dam's condition has not been rated, and it has not undergone any recent modifications or emergency action plan updates. With a spillway width of 5 feet and a maximum discharge of 36 cubic feet per second, the dam poses minimal risk to the surrounding area, making it a relatively safe and stable structure for recreational use and environmental observation.

While Henkin Pond Dam may not be a high-profile water resource project, its unique design and location in Newaygo County, Michigan, offer an opportunity for enthusiasts to study the intersection of dam infrastructure, climate, and environmental conservation. As a low-hazard dam with a history dating back to the 1960s, Henkin Pond Dam presents a case study in the importance of ongoing risk assessment and management for sustainable water resource development.

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 Henkin Pond Dam

Where does the data for Henkin Pond 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.
