Following the drinking water ban in the Toledo area in August 2014, considerable interest and attention has been paid to the complex series of factors that contribute to the release of water contaminants, most notably microsystin, into the western basin of Lake Erie with the formation of annual harmful algae blooms (HABs).

This website provides connection to an online management system that contains sources of key information on the variety of science and public policy research, studies and reports discussing Lake Erie HABs.  The system includes materials on a wide range of topics covering public health, Lake Erie water quality and HABs monitoring and forecasting, land use management practices, drinking water treatment technologies, policies and regulations, economics, and general related information.  Although much of these materials are publicly available, it is the goal of this project to provide this “one stop clearing house” so users can readily access information of interest to them.

The types of information are:  published papers and reports (on PDF format that can be downloaded by the user), existing websites, and contacts for key agencies and experts.  The system also allows for key word searches to assist the user in locating materials of interest.

It is the aim of this project to provide access to the diverse and large collection of information available on the issue of Lake Erie HABs in order to engage the wide range of stakeholders with the Maumee Basin in understanding the issues and to be involved decision-making.  This will aid engagement and community based collaboration across the watershed by highlighting the many approaches that could be employed to reduce the presence and impacts of HABs in the western basin of Lake Erie which is essential to solving the problem.
