Roberts Lake Dam dam
Roberts Lake Dam
Roberts Lake Dam, also known as South Twin Lake Dam, is a state-owned structure located in Indian River, Michigan. Completed in 1948, this earth dam stands at 7 feet tall and spans 300 feet in length, serving primarily for recreational purposes. The dam's reservoir has a storage capacity of 210 acre-feet, with a normal storage level of 93 acre-feet, covering a surface area of 54 acres.
Situated on Twin Lakes Creek in Cheboygan County, Michigan, Roberts Lake Dam is regulated by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE). The dam's spillway is uncontrolled with a width of 12 feet, and its hazard potential is categorized as low, with a satisfactory condition assessment as of the last inspection in October 2015. Despite its moderate risk assessment rating, the dam's risk management measures and emergency action plans remain unspecified.
Water resource and climate enthusiasts interested in Roberts Lake Dam can appreciate its role in supporting recreational activities in the area while also recognizing the importance of regular inspections and maintenance to ensure its continued safety and functionality. With its scenic location and historical significance dating back to the mid-20th century, this dam serves as a vital part of the local landscape and water management infrastructure in the region.
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 Roberts Lake Dam
Where does the data for Roberts 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.
