Scottish Hills Lake Dam dam
Scottish Hills Lake Dam
Scottish Hills Lake Dam, also known as Lake 20 Dam, is a privately owned structure located in Beaverton, Michigan. This earth dam, constructed in 1974, serves primarily for recreational purposes and stands at a height of 14 feet with a length of 200 feet. The dam has a storage capacity of 2,100 acre-feet and a normal storage level of 1,350 acre-feet, covering a surface area of 128 acres.
Situated on the Lake Twenty Outlet, the dam has a low hazard potential and was last inspected in June 2017, with a satisfactory condition assessment. Despite its moderate risk rating, the dam is regulated, permitted, inspected, and enforced by the Michigan Department of Environment, Great Lakes, and Energy, ensuring its structural integrity and safety for the surrounding community. With a maximum discharge capacity of 980 cubic feet per second and an uncontrolled spillway width of 50 feet, Scottish Hills Lake Dam plays a crucial role in managing water resources in the area.
Enthusiasts of water resources and climate in Gladwin, Michigan, will find Scottish Hills Lake Dam to be a fascinating structure that not only enhances recreational activities but also fulfills essential functions in water management and flood control. Its well-maintained condition, regulatory oversight, and moderate risk assessment underscore the importance of this dam in ensuring the safety and sustainability of the local environment and community.

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 Scottish Hills Lake Dam
Where does the data for Scottish Hills 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 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.
