Twin Lakes Dam dam
Twin Lakes Dam
Twin Lakes Dam in Kings Mill, Michigan, stands as a critical structure regulating water flow on the tributary to Lees Lake Drain. Completed in 1963, this State-owned dam primarily serves recreational purposes by creating a 64-acre reservoir with a normal storage capacity of 40 acre-feet. Standing at a height of 14 feet, with a controlled spillway and a maximum discharge capacity of 32 cubic feet per second, Twin Lakes Dam offers both water resource management and flood control benefits to the surrounding area.
Despite its low hazard potential and fair condition assessment, Twin Lakes Dam poses a significant risk due to its very high risk assessment rating of 1. The dam undergoes inspections every five years, with the last assessment conducted in October 2019. While the dam is State-regulated and monitored by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), there is no current Emergency Action Plan (EAP) in place. It is essential for water resource and climate enthusiasts to stay updated on Twin Lakes Dam's risk management measures and potential hazards in the event of an emergency.
With a unique design as an earth dam spanning 150 feet in length and a hydraulic height of 12.6 feet, Twin Lakes Dam offers a captivating blend of engineering and recreational opportunities. As water resource and climate enthusiasts explore the intricate details of this dam, it becomes evident that Twin Lakes Dam plays a crucial role in balancing water storage, flood control, and recreational activities in the Lapeer County region 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.

About Twin Lakes Dam
Where does the data for Twin Lakes 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.
