Managed by the Minnesota Department of Natural Resources, Geis Wetland is regulated and inspected regularly to ensure its structural integrity and environmental impact. The wetland's spillway is controlled and has a width of 25 feet, with a low hazard potential. Despite not being rated for condition assessment, Geis Wetland remains a valuable resource for water management and conservation, with a very high risk assessment due to its critical role in supporting local ecosystems and biodiversity.
In the event of an emergency, Geis Wetland is equipped with a slide (sluice gate) outlet gate and updated emergency contacts. With a risk management plan in place and ongoing monitoring, this wetland continues to play a vital role in preserving the natural landscape and supporting wildlife populations in the Redwood County area of Minnesota.
