Kokosing River

Knox County, OH

Native mussels are protected in Ohio by law, and mussel survey protocols were released in 2013 in a joint effort by the Ohio Department of Natural Resources and the U.S. Fish and Wildlife Service. EMH&T provides the resources needed to perform such mussel surveys for public and private projects throughout Ohio. Our in-house staff is certified by the State of Ohio to perform mussel reconnaissance assessments, full mussel surveys and mussel relocations.

EMH&T conducted mussel surveys and relocations for three ODOT bridge projects on the North Branch Kokosing River and Kokosing River in Knox County. Both of these are Group 1 streams. EMH&T prepared a mussel survey and relocation study plan for each of the three sites, and coordinated with the ODNR to obtain approval. Timed search surveys were conducted in accordance with the Ohio Mussel Survey Protocol and all mussels encountered were relocated upstream. At one of these sites, a total of 441 individual mussels representing 8 species were identified and relocated. The survey findings were documented in a report for each site, which was submitted to ODNR for approval and clearance.
