ABSTRACT: The St. Clair-Detroit River System (SCDRS) has undergone a number of anthropogenic changes, ranging from large-scale habitat and water-quality degradation in the early 1900's to the eventual restoration efforts occuring today. As a connecting channel between the upper and lower Great Lakes, this system serves as an important barometer for food-web disruptions within vital fish spawning and nursery habitat. At the turn of the century, more thorough and comprehensive biological surveys of the system revealed imporvments in biological integrity in response to habitat restoration. However, a majority of these surveys focused on fishery dynamics, with little attention paid to lower trophic dynamics, specifically zooplankton. From 2012-2015, comprehensive spring-fall surveys of crustacean zooplankton were completed by the U.S. Geological Survey – Great Lakes Science Center across the SCDRS in lower Lake Huron, the St. Clair River, Lake St. Clair, the Detroit River, and western Lake Erie. We provide an overview of zooplankton community composition, and dynamics within each sampling area, and identify possible abiotic factors that may influence taxa distributions. We also discuss the efficacy of our sampling regime. The collective works are within the restoration framework of the SCDRS as well as applicable to other systems undergoing revitalization.
