About this dam

Cummings Lake Dam

Cummings Lake Dam, also known as Bambi Lake Dam, is a privately-owned structure located in Shiawassee, Michigan, near the city of Shytown. Completed in 1970, this earth dam stands at a height of 21 feet and has a length of 620 feet, creating a storage capacity of 230 acre-feet for recreational purposes. Situated on Springbrook Creek, this dam serves as a crucial water resource in the area, with a maximum discharge capacity of 560 cubic feet per second.

Despite its age, Cummings Lake Dam has been well-maintained and is in satisfactory condition as of the last inspection in July 2017. The dam is regulated by the MICHIGAN DEGLE and undergoes regular inspections and enforcement to ensure its safety and functionality. With a significant hazard potential and a very high risk assessment rating, measures are in place to mitigate any potential risks and ensure the safety of the surrounding community.

The dam's controlled spillway, with a width of 5 feet, helps manage water levels and prevent flooding in the area. The dam's strategic location and design make it a vital component in the local water management system, providing both recreational opportunities and essential water resource management capabilities. As climate change continues to impact water resources, structures like Cummings Lake Dam play a crucial role in adapting to and mitigating the effects of a changing climate on water availability and management.

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 Cummings Lake Dam

Where does the data for Cummings Lake 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.
