Summary
Completed in 1977, this earth dam stands at a height of 15 feet and has a storage capacity of 88 acre-feet. While its main function is irrigation, it also provides opportunities for recreational activities in the surrounding area.
Situated on TR-Bear Creek in Montgomery County, Winter Lake Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite not being regulated or inspected by the state, the dam serves an important role in water resource management for the local community. With a surface area of 11 acres and a drainage area of 100, Winter Lake Dam contributes to the overall water ecosystem in the region.
Although lacking in certain regulatory measures, Winter Lake Dam remains a vital component of the water infrastructure in the area. With its modest size and low hazard potential, it continues to support irrigation needs while offering recreational opportunities for residents and visitors alike. As climate change impacts water resources, structures like Winter Lake Dam play a crucial role in managing and sustaining water supplies for the future.

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.
