In 2011, Lake Erie experienced its largest algal bloom in history. In 2012, the International Joint Commission (IJC) established the Lake Erie Ecosystem Priority
(LEEP) in response to a growing challenge: lake-wide changes in Lake Erie related to problems of phosphorus enrichment from both rural and urban sources,
compounded by the influence of climate change and aquatic invasive species. These changes have resulted in impaired water quality, with impacts on ecosystem
health, drinking water supplies, fisheries, recreation and tourism, and property values.
A Balanced Diet for Lake Erie: Reducing Phosphorus Loadings and Harmful Algal Blooms presents the IJC’s key findings and recommendations from the
