Unobstructed pathways are crucial for stream-dwelling trout at key times throughout the year and life cycle. Trout must be able to move freely in a stream system to reach spawning and overwintering areas, find coldwater refuge in low, warm summer flows, and access feeding grounds. However, barriers like dams, road...
This photo from Hay Creek in the State Forest illustrates how the June flood waters spread out. You can see the flattened grass. The energy release of floodplain prevented any damage to the instream habitat.
A box elder sitting on top of legacy sediment, ready to fall in and take a big chunk of the bank along with it! Mill Creek, Chatfield (Winona County). By Dr. Jennifer Biederman The Driftless Area of southeastern Minnesota, characterized by its unique topography of steep hills and deep valleys untouched by...
by Dr. Jennifer Biederman Stream restoration projects are essential for the rehabilitation of freshwater ecosystems, particularly for species such as trout, which are sensitive to environmental changes. Designing an effective trout stream restoration project involves a blend of ecological science, hydrological understanding, and community engagement. MNTU stream projects not only...
In northeastern Minnesota, where clear streams carve through thick forests and rocky ridges, the brook trout—a symbol of pristine waters—faces an uncertain future. Climate change, manifesting through rising temperatures and altered precipitation patterns, is reshaping the habitat these fish have thrived in for millennia. Flows of these streams are fueled...
A pre-construction bid meeting on Mill Creek in December ‘23, with MNTU’s contracted design engineers, MNDNR, MNTU habitat staff and potential construction firms. While late winter and early spring might not seem like the peak time for trout stream restoration in Minnesota, MNTU's habitat program is anything but dormant. Though fieldwork...
