Peshtigo dam
Peshtigo
Peshtigo is a captivating hydroelectric dam located on the Peshtigo River in Wisconsin. Built in 1907 by Mead and Seastone, this gravity dam stands at a height of 19 feet and has a hydraulic height of 13 feet. With a normal storage capacity of 1000 acre-feet and a maximum discharge of 11500 cubic feet per second, Peshtigo plays a crucial role in both hydroelectric power generation and recreational activities.
Managed by the Federal Energy Regulatory Commission, Peshtigo has a low hazard potential and a very high risk assessment rating. The dam features a controlled spillway with a width of 105 feet and is equipped with Tainter (radial) gates for water release. Despite not having a recent condition assessment available, the dam's emergency action plan was last revised in August 2020, demonstrating a commitment to safety and preparedness in case of emergencies.
With its historical significance and important role in water resource management, Peshtigo is a fascinating site for water resource and climate enthusiasts. Its location on the Peshtigo River offers a unique opportunity to study the impact of dams on the surrounding ecosystem and the benefits they provide in terms of renewable energy production and water supply. As a well-maintained and regulated structure, Peshtigo sets a high standard for dam safety and operation, showcasing the importance of responsible management of water resources in the face of climate change challenges.
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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Peshtigo
Where does the data for Peshtigo 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.
