Pankey Dam dam
Pankey Dam
Located in Oscoda, Michigan, Pankey Dam, also known as Dumka Dam, was completed in 1900 and serves primarily for recreational purposes. The dam, owned privately, stands at a height of 10 feet with a hydraulic height of 4 feet, spanning a length of 400 feet along Lost Creek. With a storage capacity of 60 acre-feet, the dam covers a surface area of 8 acres and has a drainage area of 12.4 square miles.
Managed by the Michigan Department of Environment, Great Lakes, and Energy (EGLE), Pankey Dam has a low hazard potential and is deemed to be in satisfactory condition following its last inspection in October 2017. The dam features a controlled spillway with a width of 6 feet and a maximum discharge capacity of 400 cubic feet per second. Despite its age, Pankey Dam continues to contribute to the local ecosystem while providing recreational opportunities for visitors, making it an important landmark in the region.
With its historical significance and ongoing maintenance by state regulatory agencies, Pankey Dam stands as a testament to Michigan's commitment to water resource management. As climate change continues to impact water resources, the dam serves as a vital structure for flood control and water storage, highlighting the importance of sustainable infrastructure for future generations of water resource and climate enthusiasts to appreciate and protect.

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 Pankey Dam
Where does the data for Pankey 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.
