About this dam

Oxbow Dam

Located in Oakland, Michigan, Oxbow Dam, also known as Oxbow Lake Dam, was completed in 1964 and serves a primary purpose of recreation. The earth and gravity dam stands at a height of 15 feet, with a length of 255 feet, creating a reservoir with a normal storage capacity of 6,900 acre-feet and a surface area of 290 acres. The dam is situated on the Huron River and is regulated by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE).

Oxbow Dam has a high hazard potential and a satisfactory condition assessment, with the last inspection conducted in August 2019. The dam's spillway is of the controlled type, with a width of 18 feet, and it has a maximum discharge capacity of 458 cubic feet per second. Despite its risk assessment rating of "Very High (1)," the dam's emergency action plan status and risk management measures are not currently specified, indicating potential areas for improvement to enhance public safety and environmental protection in the region.

For water resource and climate enthusiasts, Oxbow Dam offers a compelling case study in dam infrastructure management and the intersection of recreation, water storage, and environmental stewardship. As a privately owned structure on a federally regulated river system, the dam presents opportunities for collaboration between state and local agencies to ensure safe operation and maintenance practices while maximizing the benefits of its reservoir for recreational activities and ecological conservation efforts in the surrounding area.

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 Oxbow Dam

Where does the data for Oxbow 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.
