Glen Hills 7 dam
Glen Hills 7
Glen Hills 7 is a crucial structure designed by USDA NRCS and located in St. Croix, Wisconsin. This dam, completed in 1973, serves the primary purpose of flood risk reduction in the area. With a height of 34 feet and a hydraulic height of 29.5 feet, Glen Hills 7 plays a significant role in managing water levels and protecting the surrounding community from potential hazards.
The dam has a high hazard potential and is regulated by the Wisconsin Department of Natural Resources. It has a satisfactory condition assessment as of February 2019 and is inspected at a frequency of 2 times per year. With a drainage area of 2.88 square miles and a maximum discharge capacity of 904 cubic feet per second, Glen Hills 7 is a critical infrastructure for mitigating flood risks and ensuring the safety of the residents in the area.
Despite its age, Glen Hills 7 continues to fulfill its purpose effectively, with a moderate risk assessment rating of 3. The dam has a storage capacity of 490 acre-feet and serves as an essential component in the overall water resource management strategy for the region. As climate change continues to impact water resources, structures like Glen Hills 7 play a vital role in safeguarding communities against the threats of flooding and ensuring sustainable water management practices for the future.
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 7
Where does the data for Glen Hills 7 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.
