Springwood Lake #1 Dam dam
Springwood Lake #1 Dam
Located in Beaverton, Michigan, the Springwood Lake #1 Dam, also known as Twin Lakes Dam, is a privately owned structure primarily used for recreation. Completed in 1959, this earth dam stands at a height of 11 feet with a length of 200 feet, creating a reservoir with a maximum storage capacity of 320 acre-feet. The dam is regulated by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), ensuring its safety and compliance with state laws.
With a hazard potential rated as low and a satisfactory condition assessment, the Springwood Lake #1 Dam serves as a vital recreational resource for the community. The dam's controlled spillway, with a width of 15 feet, helps manage water levels in the reservoir, while its very high risk assessment ranking highlights the importance of ongoing monitoring and maintenance. Even though the dam has not been modified in recent years, regular inspections are conducted to ensure its continued safety and functionality.
In the event of an emergency, it is crucial for the dam owners to have an Emergency Action Plan (EAP) prepared and up-to-date. While the dam currently does not have an EAP in place, it is important for the owners to follow guidelines and prepare for potential risks associated with the structure. Overall, the Springwood Lake #1 Dam remains a key feature in the local landscape, providing opportunities for recreation and environmental stewardship in Clare County, Michigan.
Dam data reference
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 Springwood Lake #1 Dam
Where does the data for Springwood Lake #1 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.
