Summary
The dam, primarily made of earth, stands at a height of 27 feet and has a hydraulic height of 15 feet. With a storage capacity of 4,600 acre-feet and a surface area of 298 acres, Dexterville serves as a popular spot for outdoor activities such as fishing, boating, and wildlife observation.
Despite its low hazard potential and fair condition assessment, Dexterville has undergone modifications in 1998 to enhance its safety measures. The dam features a controlled spillway with a width of 160 feet and a maximum discharge capacity of 24,000 cubic feet per second. The risk assessment for Dexterville indicates a very high risk level, with an assigned risk category of 1. While the dam is under state regulation and inspection, it is important for water resource and climate enthusiasts to stay informed about its management and maintenance to ensure the safety of the surrounding community.
Overall, Dexterville offers a picturesque setting for outdoor enthusiasts to enjoy recreational activities in the heart of Wisconsin. With its serene waters and diverse ecosystem, the dam provides a valuable resource for both locals and visitors alike. As efforts continue to monitor and manage the dam's risk level, Dexterville remains a vital part of the region's water infrastructure and natural landscape.

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.
