Summary
21, also known as Little Bear, is a state-owned recreational dam in Wisconsin, specifically located in Jackson County near the city of Winnebago Mission. Built in 1937, this earth dam stands at a height of 9 feet and spans a length of 1230 feet, with a storage capacity of 50 acre-feet and a surface area of 11 acres. The dam regulates the flow of Dickey Creek, a tributary of the nearby river, providing essential flood control and water resource management for the region.
The dam is under the jurisdiction of the Wisconsin Department of Natural Resources (WIDNR), which oversees its permitting, inspection, and enforcement activities. Despite its low hazard potential and fair condition assessment, Resettlement Admin. 21 is categorized as having a very high risk due to its location and structure. Regular inspections are conducted to ensure the safety and integrity of the dam, with an inspection frequency of 10 years and the last assessment occurring in 2014. Although the dam currently meets guidelines for emergency action plans, additional risk management measures may need to be implemented to mitigate potential hazards and protect surrounding communities.
As a vital piece of infrastructure in the region, Resettlement Admin. 21 serves not only as a recreational site but also as a critical component of water resource management and climate adaptation efforts. Its role in regulating water flow, mitigating flood risks, and providing recreational opportunities underscores the importance of ongoing monitoring and maintenance to ensure the safety and resilience of this essential structure in the face of evolving climate challenges.

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.
