• Confluence Field Station

    In 2008, construction began on the center’s Jerry F. Costello Confluence Field Station in Alton, Illinois, near the National Great Rivers Museum and adjacent to the Melvin Price Locks and Dam. Dedicated in 2010, the field station serves as a model of green construction, with minimal environmental impact, integrated renewable energy systems, and internal recycling systems.

    Strategically located at the confluence of the Illinois, Missouri, and Mississippi Rivers, the 32,000-square-foot research facility contains laboratories, classrooms and riverside access along its eco road. Construction of Phase II, including new hydrologic and wildlife laboratories as well as additional space for offices and storage and a conference room, was completed in 2014. 

    The architecture of the building complements the surrounding environment and minimizes visual intrusion on the landscape, while sustainable design features reduces the physical and environmental impacts of the facility. The building incorporates sustainable features according to LEED (Leadership in Energy and Environmental Design) and received LEED Gold Certification in 2015.
