The presence of dreissenid mussels triggers a need for large budgets to manage water bodies that contain these mussels. Based upon dreissenid mussel behavior in the eastern US, it was assumed that mussels would be widely invasive in western US waters. After five years of monitoring, it appears that not all environments trigger invasive populations. The goal of this research is to utilize predictive modeling techniques to inform decisions regarding stewardship of natural resources.
