Wolszyk Dam dam
Wolszyk Dam
Wolszyk Dam, located in Alpena, Michigan, was completed in 1962 and is primarily used for recreation purposes. The dam, with a height of 14 feet and a length of 200 feet, has a storage capacity of 180 acre-feet and sits on the Trib N Br Thunderbay River. Managed by USDA NRCS, Wolszyk Dam has a low hazard potential and is classified as an Earth dam type.
With its picturesque location in Presque Isle County, Wolszyk Dam offers visitors a tranquil setting for outdoor activities such as boating, fishing, and hiking. The dam plays a crucial role in water resource management in the region, providing a controlled release of water and ensuring conservation of the surrounding ecosystem. Despite its low hazard potential, the dam's condition assessment is currently not available, highlighting the importance of regular inspections and maintenance to ensure its long-term functionality.
As a key feature in the Detroit District, Wolszyk Dam serves as a vital component in the local water infrastructure, contributing to flood control and water supply management efforts. Its close proximity to Alpena and the Thunderbay River makes it a popular destination for both locals and tourists, showcasing the intersection of water resource management and recreational opportunities. With its rich history and scenic surroundings, Wolszyk Dam stands as a testament to the importance of sustainable water resource practices in the face of changing climate conditions.

About Wolszyk Dam
Where does the data for Wolszyk 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 below 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.

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.
