Ottogan Dam dam
Ottogan Dam
Ottogan Dam, also known as Teusink's Farm Dam, is a privately owned structure located in Holland, Michigan. Completed in 1989, this earth dam stands at a height of 17.9 feet along the Ottogan Inter-County Drain, serving primarily for flood risk reduction purposes. With a storage capacity of 75 acre-feet and a drainage area of 0.77 square miles, Ottogan Dam plays a crucial role in managing water levels and mitigating flood risks in the region.
Managed by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), Ottogan Dam has a significant hazard potential due to its location and design. Despite this, the dam's condition is assessed as satisfactory, with regular inspections conducted to ensure its structural integrity. In the event of an emergency, it is important for the owners to have an Emergency Action Plan (EAP) in place to guide response efforts. Overall, Ottogan Dam represents a vital piece of infrastructure in the region's water resource management and climate resilience efforts.
As an uncontrolled spillway type dam, Ottogan Dam has a spillway width of 55 feet and a hydraulic height of 16.7 feet. The dam's risk assessment is classified as moderate, with measures in place to manage potential risks. With its strategic location and role in flood risk reduction, Ottogan Dam stands as a testament to the importance of effective water resource management in safeguarding communities against the impacts of climate change.
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 Ottogan Dam
Where does the data for Ottogan 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 Significant 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.
