Summary
Situated along the Yellow Medicine River, the refuge offers a haven for water resource and climate enthusiasts to explore the diverse ecosystem of the region. The dam at the refuge, primarily a rockfill structure with a height of 20.7 feet, provides important water storage for the area, with a normal storage capacity of 16 acre-feet and a drainage area of 0.56 square miles.
Despite its low hazard potential, the dam at Tallgrass Wildlife Refuge plays a crucial role in managing water resources in the region, enhancing the habitat for various wildlife species. The site's condition assessment is currently marked as "Not Rated," reflecting the need for ongoing monitoring and maintenance to ensure the safety and efficiency of the dam. With its scenic location and potential for outdoor recreation, the refuge serves as a valuable resource for both conservation and education.
Visitors to Tallgrass Wildlife Refuge can learn about the importance of water management and conservation efforts while enjoying the natural beauty of the area. The presence of the dam highlights the delicate balance between human infrastructure and environmental preservation, making it a fascinating destination for those interested in sustainable practices and the interconnectedness of water resources and climate dynamics.

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.
