FishPass is an innovative project to enhance fish passage and connectivity between the Boardman (Ottaway) River and Lake Michigan, while removing invasive or non-desirable fishes through controlled sorting. FishPass will replace the deteriorating Union Street Dam in downtown Traverse City, Michigan with an improved barrier featuring a fish-sorting channel and a nature-like river channel. Once constructed, scientists will optimize various sorting technologies and techniques below the barrier to maximize efficiency of passing desirable fishes and removing invasive fishes. For example, water velocity barriers, light guidance, video shape recognition, and eel ladder style traps are just some technologies that could be integrated at the facility to sort fish and effectively pass or remove animals. The project will develop into a living laboratory with a strong education and outreach component. Once optimized for bi-directional (up and downstream) selective fish passage, FishPass will be converted to a permanent selective fishway completing the Boardman River Restoration Project. Lessons learned from the optimization phase will be applied to similar rivers to create selective fish passage at new sites. The project could have regional, national, and global implications.
