Native plants Najas guadalupensis and Elodea canadensis, and the submersed annuals, Potamogeton foliosus, P. pusillus var.pusillus, and Najas flexilis returned likely due to the water clarity brought about by the introduction of zebra and quagga mussels.

Quagga mussels (Dreissena bugensis) are filter-feeders and at high abundances remove substantial amounts of phytoplankton and suspended particulates from the water. Spring phytoplankton biomass and primary production, which can be primarily attributed to diatoms, decreased 87% and 70%, respectively, in Lake Michigan from 1995-98 to 2007-08

Conditions in Lake Michigan, especially in the critical late winter to spring season, indicate that the southern basin is transforming into a more oligotrophic condition possibily due to Dreissena bugensis, similar to that of Lake Superior in terms of levels of nutrients, chlorophyll, and primary production

Increasing amounts of pseudofeces and biodeposits could also have an impact on multiple trophic levels via changes to the physical environment. A current study in Brocton Shoal, Lake Erie, suggests that colonization of lakebed areas by dreissenid mussels (Dreissena bugensis) and the consequent filling of remaining interstitial spaces with pseudofeces and fine-grained sediments may significantly eliminate valuable habitat native habitat . Brocton Shoal, once thought to be an important area for lake trout spawning, has diminished suitability as a spawning ground.
