New Project to Investigate Worsening Green Bay Hypoxia Problem

Evidence suggests that hypoxia within Green Bay, Wisconsin, a decades-old problem, may be worsening and could potentially increase “dead zones” and fish kills. Green Bay is particularly vulnerable to hypoxia because it receives runoff from one-third of Lake Michigan’s watershed.  The excess nutrients from this runoff stimulate algal blooms that lead to hypoxia. NCCOS sponsored scientists have been awarded first year funding for a four-year project through NCCOS’ Coastal Hypoxia Research Program to research the causes and environmental impacts of hypoxia in Green Bay.  A team from the University of Wisconsin system, Green Bay Metropolitan Sewerage District, and Wisconsin Department of Natural Resources will develop a predictive model of potential changes in hypoxia relative to land use change and future climate change. The results will help identify acceptable limits for nutrient levels in the water to reduce hypoxia in Green Bay. For more information, contact Suzanne Bricker at (301) 713-3020 x 139 or
