The groundwater contained in confined glacial aquifers provides clean drinking water to many Minnesota residents. An important factor affecting the long-term sustainability of these aquifers is how water infiltrates through clayey deposits of overlying glacial till, which act as barriers to contaminants but also limit water flow and aquifer recharge. Very little is actually known about the properties and infiltration of water through till, which hinders the ability to accurately define the sustainability of these aquifers.
Granite rock outcrops along the Upper Minnesota River are among the oldest exposed rock in North America, dating back approximately 3.6 billion years. These outcrops are also home to rare and specialized plant and animal communities rarely found elsewhere in Minnesota, including several types of cactus and one of Minnesota's only three lizard species, the five-lined skink. However, these rock outcrops are increasingly threatened by mining, overgrazing, and development.
This grant application will focus on the construction of multiple targeted best management practices (BMPs) in priority areas which will provide measurable reductions in sediment and phosphorus loadings to cold water streams in the Mississippi River/Lake Pepin Watershed. The installation of these BMPs will also protect the existing stream habitat by reducing peak flows and reduced streambank erosion.
