Dead Horse Slough dam
Dead Horse Slough
Located in Ashland, Wisconsin, Dead Horse Slough is a state-regulated water resource with a high hazard potential and fair condition assessment. This structure, completed with a dam height of 19 feet and a hydraulic height of 7 feet, serves to control water flow and store up to 900 acre-feet of water. With a drainage area of 5.9 square miles and a spillway type classified as 'Uncontrolled', Dead Horse Slough plays a crucial role in managing water levels in the region.
Despite its moderate risk assessment and frequent inspections every two years, Dead Horse Slough continues to be a key asset in the state's water management efforts. Its location at coordinates 46.1551387 latitude and -90.8577021 longitude makes it a vital component of the water infrastructure in the area. While it lacks associated structures and detailed information on its construction and maintenance history, the presence of state regulation, permitting, inspection, and enforcement ensures that Dead Horse Slough remains a reliable and essential resource for water resource and climate enthusiasts in the region.
With a capacity to store 900 acre-feet of water and a surface area of 100 acres, Dead Horse Slough not only provides flood control but also supports various ecological functions. As water resource and climate enthusiasts monitor its condition and regulatory compliance, the dam continues to play a significant role in ensuring water security and management in Ashland, Wisconsin. As efforts to enhance its risk management measures and emergency preparedness continue, Dead Horse Slough remains a critical structure in the state's water infrastructure landscape.
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 Dead Horse Slough
Where does the data for Dead Horse Slough 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 High 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.
