About this dam

Bergland Dam

Bergland Dam, also known as Lake Gogebic Dam, is a private-owned structure located in Ontonagon, Michigan. Completed in 1906, this dam plays a crucial role in regulating the flow of the West Branch Ontonagon River, providing essential water resource management for the surrounding area. With a height of 8 feet and a length of 179 feet, Bergland Dam has a maximum storage capacity of 276,000 acre-feet and a normal storage capacity of 35,200 acre-feet, ensuring a steady water supply for various purposes.

Despite being categorized as having a low hazard potential, Bergland Dam is subject to regular inspections by the state regulatory agency of MICHIGAN DEGLE to ensure its structural integrity and compliance with safety standards. The risk assessment for the dam is moderate, indicating a need for ongoing risk management measures. Additionally, with a spillway type of "Uncontrolled" and a spillway width of 179 feet, the dam is designed to handle a maximum discharge of 10,000 cubic feet per second in times of high water flow, highlighting its importance in mitigating flooding and protecting downstream communities.

As a key component of the local water infrastructure, Bergland Dam serves as a vital resource for water supply, flood control, and environmental conservation in the region. With its long history of operation and maintenance, the dam continues to play a significant role in sustaining the ecological balance of the area while also providing recreational opportunities for residents and visitors alike. The strategic location of Bergland Dam on the West Branch Ontonagon River further underscores its importance in water resource management and climate resilience efforts in Michigan.

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 Bergland Dam

Where does the data for Bergland 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.

Premium feature
