Scientists are testing technology downstream of the Boardman River’s Union Street Dam in Traverse City. This initiative, known as FishPass, aims to identify and refine technology to block undesirable species like sea lampreys while allowing the passage of desirable species like sturgeon. Technology developed at the Union Street Dam in Traverse City could be used at the new AHS structure to maximize the passage of desirable fish while blocking sea lamprey and other undesirable species.
