Welcome to the Midwest Region! Our region includes 19 Science Centers in 12 States from the Great Lakes to the Dakotas, south to Missouri and Kentucky. Our streamgage network is used to monitor and assess water resources across the region. Other research focuses on fisheries and aquatic ecosystems, midcontinental plant/animal species, invasive species, wildlife disease, and energy and mining.

Large River Science in MO River Basin
April 14, 2018

Expertise in large river research provides science information to inform decisions on river management and restoration in the Midwest Region. Connectivity is a fundamental concept in river ecology and refers to opportunities for water to flow along and through riverine ecosystems. It is considered one of the primary drivers of river productivity, biological diversity and ecosystem health.
