Summary
With a storage capacity of 490 acre-feet and a surface area of 4 acres, this low hazard dam serves the primary purpose of supporting aquatic habitats and wildlife conservation efforts. The dam stands at a height of 11 feet and is classified as an earth and buttress type structure.
Owned and regulated by the Minnesota Department of Natural Resources, Anderson Lake boasts a satisfactory condition assessment as of May 2018, indicating its operational efficiency and safety. Despite its low hazard potential, the dam undergoes inspections every 8 years to ensure its continued functionality. With a drainage area of 22.6 square miles, the reservoir plays a vital role in maintaining the ecological balance of the surrounding area.
Enthusiasts of water resources and climate conservation will find Anderson Lake to be a significant contributor to the local ecosystem, providing essential support for fish and wildlife populations. Its location on the Yellow Medicine River adds to its ecological importance, making it a key component of the natural landscape in Lincoln County, Minnesota. As a state-regulated structure with a focus on environmental preservation, Anderson Lake stands as a testament to the ongoing efforts to protect and sustainably manage water resources in the region.

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.
