Summary

Constructed in 1864, this gravity dam serves primarily for recreational purposes, providing a peaceful retreat for visitors to enjoy the picturesque surroundings. With a structural height of 30 feet and a storage capacity of 440 acre-feet, the dam plays a crucial role in regulating water flow and maintaining the ecological balance of the Caz Br to Little Baraboo river system.

Managed by the Wisconsin Department of Natural Resources (WIDNR), the Cazenovia Dam has been deemed to have a significant hazard potential, highlighting the importance of regular inspections and maintenance to ensure its continued safety and functionality. Despite this, the dam's condition was assessed as satisfactory as of November 2020, reflecting the dedication of local authorities to upholding high standards of dam safety. With a risk assessment categorizing the dam as having a very high risk level, ongoing risk management measures are essential to mitigate potential threats and safeguard the surrounding community.

As an integral part of the Richland County landscape, the Cazenovia Dam serves as a symbol of the intersection between human development and natural resource conservation. With its controlled spillway and impressive size, the dam not only enhances the area's recreational offerings but also plays a crucial role in flood control and water supply management. By prioritizing the dam's safety and resilience in the face of changing climate conditions, Cazenovia demonstrates a proactive approach to sustainable water resource management that serves as a model for other communities to follow.

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. 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

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, 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.
