Glen Hills 4 dam
Glen Hills 4
Glen Hills 4, a flood risk reduction structure located in Glenwood City, Wisconsin, is a vital asset in protecting the surrounding area from potential flooding events. Constructed in 1966 by the USDA NRCS, this dam stands at a height of 32 feet and spans a length of 520 feet, with a storage capacity of 178 acre-feet. The dam's primary purpose is to control debris and reduce flood risks, making it a crucial component in managing water resources in the region.
Managed by the Wisconsin Department of Natural Resources, Glen Hills 4 is subject to regular inspections to ensure its structural integrity and effectiveness in flood risk reduction. With a high hazard potential and a satisfactory condition assessment, the dam plays a key role in mitigating flood risks for the local community. Despite its age, the dam has undergone modifications in 2002 to enhance its performance, reflecting a commitment to maintaining and improving water infrastructure for climate resilience.
As a tributary to Tiffany Creek, Glen Hills 4 serves as a critical piece of infrastructure in the Detroit District, contributing to the overall water management efforts in the region. With a moderate risk assessment rating, the dam continues to be a valuable asset in safeguarding against potential flooding events and protecting the surrounding environment. Its location, design, and operational history make Glen Hills 4 a noteworthy structure for water resource and climate enthusiasts interested in sustainable water management practices.
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 Glen Hills 4
Where does the data for Glen Hills 4 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.
