The Cooperative Science and Monitoring Initiative (CSMI) is a binational effort that coordinates monitoring and research efforts on each Great Lake over a five-year cycle to improve understanding of aquatic ecosystems. CSMI field sampling is guided by priorities identified in Lakewide Action and Management Plans (LaMPs) and the results inform the development of future management programs. This document highlights the work intended to be conducted during the 2015 CSMI field year on Lake Michigan.
