Uihlein dam
Uihlein
Uihlein, also known as Maple Spring and Ryan, is a privately owned dam located in Ashland, Wisconsin. Built in 1974, this earth-type dam stands at 18 feet high and serves primarily for recreational purposes. With a normal storage capacity of 49 acre-feet and a maximum storage of 103 acre-feet, Uihlein is situated on TR Trout Brook within the St. Paul District.
Despite being categorized as low hazard potential and fair condition assessment, Uihlein is subject to state regulation, inspection, and enforcement by the Wisconsin Department of Natural Resources. The dam's moderate risk assessment indicates a potential for issues that may require management measures in the future. With an uncontrolled spillway and a drainage area of 0.2 square miles, Uihlein offers a glimpse into the delicate balance between water resource management and recreational use in the region.
Enthusiasts of water resources and climate will find Uihlein to be an intriguing case study, showcasing the intersection of recreational infrastructure, environmental regulations, and risk assessment. As a privately owned structure, Uihlein presents unique challenges and opportunities for sustainable management practices. Its location in Ashland, Wisconsin, along with its historical significance and potential impact on the surrounding ecosystem, make Uihlein a focal point for those interested in the intricate relationship between water resources and human activities in the region.

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 Uihlein
Where does the data for Uihlein 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.
