“From Sea to Source” is an international program reminding us that rivers are, at a basic level, means of transporting materials to the ocean. “Materials” in this case means fish, which are easily overshadowed by all of our other river concerns.
In southeast Minnesota, we are fortunate to have an abundant supply of groundwater. It is the water we drink and the source of water in local trout streams. However, the unique geology of this region makes it vulnerable to contamination. A complex network of cracks, open channels, and caves below the surface provides a quick and direct path for surface water to reach groundwater. As water travels over the landscape it can carry contaminants such as bacteria, pesticides, fertilizers and road salt underground.
