Summary
With a structural height of 9 feet and a length of 50 feet, the dam has a storage capacity of 110 acre-feet and serves multiple purposes such as irrigation, recreation, and water supply. Despite its low hazard potential, the dam's condition assessment is poor, indicating a need for maintenance and potential improvements to ensure its long-term reliability and safety.
This dam is under state regulation by the Wisconsin Department of Natural Resources (WIDNR), with state permitting, inspection, and enforcement in place. Although the last inspection was conducted in 2012, the dam's condition was assessed as poor in 2017, highlighting the need for regular maintenance and assessment to mitigate any risks associated with its operation. The dam's maximum discharge capacity is 687 cubic feet per second, with a controlled spillway type in place to manage excess water flow during high water events.
Despite its age and condition assessment, Clark County 16 continues to play a crucial role in providing irrigation water to the surrounding area. As a key water resource in the region, it is essential to ensure its proper maintenance and operational readiness to meet the water supply needs of the community while also addressing any potential safety concerns. Climate enthusiasts and water resource managers should keep a close eye on this dam to ensure its continued functionality and safety in the face of changing climate conditions and evolving water resource management practices.

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.
