The Lake Michigan Lakewide Action and Management Plan (LAMP) is an ecosystem-based management strategy for protecting and restoring the water quality of Lake Michigan. This 2018 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 Michigan Partnership, which is led by the U.S. Environmental Protection Agency and which facilitates information sharing, sets priorities, and assists in coordinating environmental protection and restoration activities. The next Lake Michigan LAMP will be released in 2020; in the interim, the Lake Michigan Partnership will be assessing the state of the lake, measuring progress and promoting action to address identified problems.
