Wambold dam
Wambold
Wambold, also known as Eagle Spring Lake, is a gravity dam located in Waukesha, Wisconsin, with the primary purpose of recreation. Completed in 1836, this historic structure stands at a height of 12 feet and spans a length of 301 feet. With a normal storage capacity of 1127 acre-feet and a drainage area of 22 square miles, Wambold serves as a vital water resource for the surrounding community.
Managed by the Wisconsin Department of Natural Resources (WIDNR), Wambold has a state-regulated status, with regular inspections and enforcement to ensure its structural integrity. Despite being classified as having a significant hazard potential, the dam is currently in fair condition as of the last assessment in May 2020. In the event of an emergency, the dam has an Emergency Action Plan (EAP) in place to guide response efforts, although it was last revised in 2014.
Water resource and climate enthusiasts will appreciate the historical significance and environmental impact of Wambold, as well as the ongoing efforts to manage its risk and ensure public safety. Located along the Mukwonago River in EAGLEVILLE, Wisconsin, this dam not only provides recreational opportunities but also plays a critical role in water storage and management for the region. With its controlled spillway and very high risk assessment rating, Wambold remains a focal point for conservation and sustainable water resource practices in the area.
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 Wambold
Where does the data for Wambold 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.
