About this dam

Maybury Fish Pond Dam

Maybury Fish Pond Dam located in Northville, Michigan, is a state-regulated earth dam that serves primarily for recreational purposes. Completed in 1979, this dam has a height of 18.5 feet and a hydraulic height of 15.4 feet, with a storage capacity of 118 acre-feet. The dam impounds water from a tributary to Johnson Drain and has a drainage area of 0.91 square miles.

With a spillway width of 9 feet and a maximum discharge capacity of 80 cubic feet per second, Maybury Fish Pond Dam poses a significant hazard potential but is currently in satisfactory condition based on a 2019 inspection. Despite its moderate risk assessment rating, the dam lacks an Emergency Action Plan (EAP) and inundation maps, raising concerns about emergency preparedness in the event of a breach. The dam is under the jurisdiction of the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), and is subject to regular inspections and enforcement to ensure public safety and environmental protection. For water resource and climate enthusiasts, Maybury Fish Pond Dam presents an interesting case study in dam safety and management practices in the state of 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 Maybury Fish Pond Dam

Where does the data for Maybury Fish 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 Significant 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.
