Summary
Croix, Wisconsin, designed by the USDA NRCS to primarily serve the purpose of flood risk reduction along Beaver Creek. This earth dam, completed in 1970, stands at a towering height of 64 feet and features a controlled spillway with a width of 99 feet. With a storage capacity of 3,845 acre-feet and a drainage area of 10 square miles, this dam plays a significant role in mitigating the high hazard potential posed by potential flooding in the region.
Maintained and regulated by the Wisconsin Department of Natural Resources, Glen Hills 10 has been deemed to be in satisfactory condition, with a very high risk assessment rating. The dam's inspection frequency of 2 years ensures its structural integrity, while emergency action plans are in place to manage any unforeseen events effectively. Operating under the jurisdiction of the Detroit District of the US Army Corps of Engineers, this infrastructure not only serves flood risk reduction but also contributes to debris control and recreational activities in the area, making it an essential component of water resource management in St. Croix, Wisconsin.
For water resource and climate enthusiasts, Glen Hills 10 presents a fascinating case study of effective flood risk reduction through infrastructure design and regulatory oversight. With its strategic location and significant storage capacity, this earth dam not only safeguards the surrounding communities from potential flooding but also supports recreational activities along Beaver Creek. As climate change continues to impact water resources, the importance of structures like Glen Hills 10 in ensuring resilience and sustainability in the face of environmental challenges cannot be overstated.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
