The Lake Superior Lakewide Action and Management Plan (LAMP) is a binational ecosystem- based strategy for protecting and restoring the water quality of Lake Superior. This 2019 Annual Report highlights accomplishments and progress during the past year including outreach, monitoring, and protection and restoration actions. The LAMP is developed and implemented by the Lake Superior Partnership, which is led by the U.S. Environmental Protection Agency and Environment and Climate Change Canada and which facilitates information sharing, sets priorities, and assists in coordinating binational environmental protection and restoration activities. The next Lake Superior LAMP is scheduled to be released in 2021; in the interim, the Lake Superior Partnership will be assessing the state of the lake, measuring progress and promoting action to address identified problems.
