Holzer Flowage dam
Holzer Flowage
Holzer Flowage, also known as Pershing Wildlife Area #2, is a state-owned recreational area located in Taylor County, Wisconsin. The dam, completed in 1962, is primarily used for recreation purposes and stands at a height of 7.6 feet with a hydraulic height of 7 feet. The flowage has a storage capacity of 180 acre-feet and covers a surface area of 55 acres, making it a popular destination for water resource and climate enthusiasts.
The dam at Holzer Flowage has a controlled spillway type and a low hazard potential, with a fair condition assessment as of May 2020. Despite its relatively low hazard potential, the flowage is situated in an area with a very high risk assessment (1), underscoring the importance of proper risk management measures. While the flowage has not been significantly modified over the years, regular inspections are conducted with a frequency of 10 years to ensure its structural integrity and safety.
For those interested in exploring water resources and climate dynamics, Holzer Flowage offers a picturesque setting with opportunities for outdoor recreation and environmental observation. Its location along the TR-SHOULDER CR river/stream in Wisconsin provides a unique perspective on the intersection of water management, recreational activities, and natural ecosystems. With its low hazard potential and fair condition assessment, Holzer Flowage serves as a valuable case study for understanding the maintenance and management of dam infrastructure in the context of changing climate patterns and environmental risks.

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 Holzer Flowage
Where does the data for Holzer Flowage 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.
