Haymeadow Dam dam
Haymeadow Dam
Haymeadow Dam, located in Three Lakes, Wisconsin, serves as a crucial feature for fish and wildlife preservation in the area. Built in 1956 by the USDA Forest Service, this Earth-type dam stands at a height of 11 feet and has a structural height of 14 feet. With a normal storage capacity of 725 acre-feet and a maximum discharge of 172 cubic feet per second, the dam plays a vital role in managing the water resources of the region, particularly for Haymeadow Creek.
Despite being classified as having a low hazard potential, Haymeadow Dam is subject to regular inspections by the Forest Service to ensure its structural integrity and safe operation. The dam boasts an uncontrolled spillway with a width of 15 feet, further enhancing its ability to manage water flow in the area. With a risk assessment rating of moderate (3), measures are in place to mitigate any potential risks associated with the dam and ensure the safety of surrounding communities.
As a significant feature in the conservation efforts of the Forest Service, Haymeadow Dam continues to stand as a testament to the importance of sustainable water resource management in the face of changing climate patterns. Its role in maintaining the ecological balance of the region, coupled with its low hazard potential and efficient design, highlights the importance of such infrastructure in safeguarding our water resources for future generations.
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 Haymeadow Dam
Where does the data for Haymeadow 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 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.
