Suukjak Sep dam
Suukjak Sep
Suukjak Sep is a federal-owned dam located in Fort Mc Coy, Wisconsin, along the Squaw Creek. Built in 1961 by Ayers & Assoc., this earth dam stands at a height of 24 feet and spans 400 feet in length. The dam serves a primary purpose of recreation, offering a storage capacity of 315 acre-feet and a surface area of 14 acres for outdoor activities. With a significant hazard potential and a moderate risk assessment rating, Suukjak Sep is closely monitored by the US Army, who also oversees its funding, design, construction, regulation, inspection, and operation.
Despite not being regulated by the state, Suukjak Sep is a key feature in the St. Paul District managed by the US Army. The dam's spillway type is uncontrolled, with a width of 74 feet, capable of handling a maximum discharge of 2000 cubic feet per second. While the condition assessment is currently unavailable, the dam is inspected every 4 years to ensure its safety and functionality. With its location in Monroe County and its close proximity to the city of Fort Mc Coy, Suukjak Sep offers a recreational oasis for water resource and climate enthusiasts to enjoy nature and outdoor activities amidst the scenic surroundings of Squaw Creek.
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 Suukjak Sep
Where does the data for Suukjak Sep 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.
