Gerhard Dam dam
Gerhard Dam
Gerhard Dam, also known as Hitchens or Bolling Dam, is a private earth dam located in Traverse City, Michigan. Built in 1960 by the USDA NRCS, this recreational dam stands at 25 feet high and spans 505 feet in length. Situated on a tributary to Mitchell Creek, the dam serves primarily for recreation purposes, offering a serene getaway for water resource and climate enthusiasts.
Managed by the Michigan Department of Environment, Great Lakes, and Energy, Gerhard Dam has a low hazard potential and is deemed to be in satisfactory condition as of its last inspection in September 2019. With a normal storage capacity of 44 acre-feet and a drainage area of 0.76 square miles, the dam provides a picturesque setting for outdoor activities, attracting visitors to its 5-acre surface area for fishing, boating, and relaxation.
Although the dam has an uncontrolled spillway type, its moderate risk assessment level of 3 indicates a need for ongoing monitoring and risk management measures. Despite this, Gerhard Dam continues to be a popular destination for those seeking to enjoy the natural beauty of Grand Traverse County, offering a peaceful oasis for water resource and climate enthusiasts to appreciate and explore.
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 Gerhard Dam
Where does the data for Gerhard 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.
