Summary
Completed in 1938, this Earth-type dam stands at a height of 8 feet with a hydraulic height of 2 feet and a structural height of 8 feet. The dam spans 23,000 feet in length and has a storage capacity of 2,300 acre-feet, with a normal storage level of 800 acre-feet.
Situated on the Beaver Creek Drainage Ditch, Meadow Valley Spillway 4 has a low hazard potential and is classified as having a moderate risk level. Despite its age, the dam remains in a condition that has not been rated, with its last inspection dating back to September 2011. While it lacks Emergency Action Plan preparedness details, it falls under state regulation, with Wisconsin's Department of Natural Resources overseeing its permitting, inspection, and enforcement processes.
Water resource and climate enthusiasts can appreciate Meadow Valley Spillway 4 as a historic structure that contributes to the recreational landscape of Wisconsin. Its moderate risk level and low hazard potential make it an intriguing site for further study and monitoring in the context of changing climate patterns and water resource management practices. With its location in a picturesque natural setting, this dam stands as a testament to the intersection of human engineering and environmental stewardship.

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.
