Beaver Dam Dispute Threatens Historic Minnesota Town Hall
Rising floodwaters from a beaver dam have created a stalemate in Scandia, Minnesota, endangering historic buildings and infrastructure.
A colony of beavers has caused escalating issues in Scandia, Minnesota, a town northeast of the Twin Cities, where their relentless dam-building has led to flooding that threatens historic structures and local infrastructure.
The rising water levels, caused by a dam constructed by beavers in a wetland south of City Hall, have inundated parts of the Gammelgarden Museum grounds, a site dedicated to preserving the heritage of Swedish immigrants. Mature trees have died, gardens have been destroyed, and a prairie restoration project has been abandoned. The museum's executive director, Ann Rinkenberger, expressed concern that the water's proximity to historic buildings, including one dating back to the 1860s, could lead to catastrophic damage to priceless artifacts.
The core of the problem lies in a property dispute. While the city owns much of the surrounding wetland, the crucial section where the dam is located belongs to a private landowner. Scandia has a drainage and utility easement on the property, but city officials require permission from the owner to access and remove the dam. This permission has been refused, as the landowners fear that dam removal would cause flooding on their own property and are seeking a permanent solution rather than a temporary fix.
This standoff has left city officials exploring options, including legal action, and seeking intervention from other agencies. However, the Carnelian-Marine-St. Croix Watershed District has stated that the issue falls within Scandia's boundaries and is outside their jurisdiction, which typically addresses drainage issues spanning multiple municipalities. Mike Isensee, the district's administrator, noted that beavers thrive in areas with abundant water resources, and managing the consequences is part of maintaining drainage systems.
The flooding has also impacted county infrastructure. For the first time, water has submerged the culvert beneath Olinda Trail Road, raising concerns about road saturation. Washington County officials are monitoring the situation and collaborating with relevant agencies to address the beaver activity and protect county roads.
One potential solution being considered is a beaver baffle, a pipe system designed to regulate water levels. The City Council has directed staff to continue discussions with other agencies regarding this and other approaches. Meanwhile, museum officials fear that each delay increases the risk of irreversible damage to the historic grounds and structures, with the cost of damage and restoration yet to be fully calculated.
